Keeping the elderly comfortable

Keeping the elderly comfortable

Troldtekt A/S

Controlling noise and acoustics is a key element in design and particularly when designing for the elderly. The need for more assisted-living and retirement accommodation continues to rise to match the ever-growing ageing population whether it’s to combat the cost of living independently, downsizing, increased care needs or just a sense of community and freedom.Care Homes and Day Centres play an important role in our society and can improve the quality of life for its users through an increased sense of security and to combat isolation. New accommodation is frequently designed to replicate the comforts of a home and to minimise transitional stress but all too frequently ambient levels of noise add to the challenges faced by the elderly. The impact of noise pollution on the elderly is far worse than in younger years. Presbycusis, (hearing loss that occurs gradually for many of us as we grow older) along with cumulative lifetime noise exposure, decline in physiological resilience and dementia all have an impact. The McManus and McClenaghan (2010) study recommended that “having a good acoustic environment can support inclusion and reduce confusion in people with dementia”. Today’s trends of designing with hard surfaces means that all too often the problem is exacerbated with residents, staff and visitors suffering from noise pollution adding to increased levels of stress and anxiety.Danish acoustic panel manufacturer Troldtekt is a world leader in designing and developing acoustic panels to create calm, healthy, comfortable environments with their long-lasting solutions for effective sound control combined with colour to create characterful design. Troldtekt acoustic panels are available in a variety of different structures and colours combining superior sound absorption with award-winning design. The Troldtekt range has a minimum expected life cycle of 50 years coupled with excellent resistance to humidity and tested to meet ball impact standards. The range is available in various sizes and structures, from extreme fine to coarse. They can be supplied as natural wood or finished in almost any RAL or NCS colour. Depending on the panel specified, reaction to fire is classed in accordance with EN 13501 as B-s1,d0 or A2-s1,d0 respectively.

Addressing reverberation within St Bronaghs Primary School, Ireland

Addressing reverberation within St Bronaghs Primary School, Ireland

Hush Acoustics

St Bronagh’s Primary School in Rostrevor, County Down was a newly built school designed by Donnelly O Neill Architects Ltd and constructed by Ganson Building & Civil engineering contractors Ltd.The £3.9 million school was crowned with the Sustainability award in May 2018, replacing the former Convent of Mercy Primary School. This was demolished to make way for this new 7x classroom building, along with the construction of a new youth club building, sports hall, community and games room, and additional accommodation.Upon handover and occupancy, it became apparent that there was scope for improving the acoustic conditions within the new building.The school design itself, was made up of 7x ‘pods’ all of varying heights and reverberation within these areas was an acoustic concern. Working with the Project Architect Paul McMahon of Donnelly O Neill Architects Ltd, we identified that significant improvements could be delivered with the installation of 425 m2 of our Hush Absorber 50 panels to classrooms and resource areas.For practical and aesthetic reasons as well as meeting the required reverberation times, we supplied 286x Hush Absorbing Notice Boards in a neutral colour with a bespoke frame colour to ensure that they blended in with the existing décor.In certain areas we were asked to create a feature wall with the panels and so we used our Hush Absorber 50 panels which were provided in 4 vibrant colours to create both a statement to the chosen rooms as well meeting the required reverberation time.We also provided 3x large printed 50mm panels at high level within the staffroom. These panels were printed with an image of the Cloughmore Stone as requested by the school. The Cloughmore stone is significant to the area and is a giant 50 tonnes granite boulder that sits high above the village of Rostrevor.As well as creating a tailored interior design, the sound absorbing panels provide a practical and efficient way of dampening sound reverberation and eliminating echoes within the rooms.We worked closely with our stockists Commercial Connections in Crossgar, County Down to ensure both site presence and swift responses to technical and installation queries were met. Ganson UK and Hush were able to ensure that all material was supplied over an 8-week period to meet the time frames on site.A multitude of sustainable elements has made this school a successful build and getting the acoustics right has significantly contributed to the school’s success.

Noise Free Housing for Happy Living

Noise Free Housing for Happy Living

Troldtekt A/S

Good acoustics, like high quality thermal insulation, is one of the most important considerations for house builders and architects. This is because of high density living and, in particular, the popularity of sold floors. For example, one of the latest trends are concrete floors. The problem is further exacerbated by the desire for large areas of glass and the absence of soft furnishings, such as curtains and carpets. The result of all this is that absorption of sound is difficult creating an unpleasant environment. One solution is to line the ceilings with cost effective and high performance Troldtekt acoustic panels.

Soundproofing internal walls and floors in apartment conversion, Hertfordshire

Soundproofing internal walls and floors in apartment conversion, Hertfordshire

Hush Acoustics

Tudor House was opened as the offices for Hatfield Rural District Council by the Marquess of Salisbury in 1930. A grand old building, it was built in a Georgian style with a host of period features.When its purpose as a public administration building was over, a proposal for a conversion (material change of use) into apartments was put forward by Lioncrest. Whilst not a listed building, they proposed to retain all of the period features and, where time had taken its toll on the building fabric, restore and renovate the brickwork and stonework back to its former glory.Permission has been given to convert the offices into seven new luxury apartments comprising of four two bedroom apartments and three one bed apartments. The largest apartment was constructed in the roof space which entailed reconstructing the existing roof incorporating two large dormer windows and five roof lights. The building includes a large basement which was converted into stores for the occupants and for each of the apartments to have an allocated car parking space.Lioncrest consulted with Hush Acoustics at the design stage of this development for soundproofing advice and assistance with the design, specification and supply of the materials needed.There were a number of design issues to take into account due to the history of the building and the period features. Our soundproofing experts worked closely with Lioncrest to develop the most economical and convenient acoustic system to achieve the high results sought. The detailed and careful installation of the Hush materials allowed some fantastic sound reducing results giving the owners of the apartments a very good standard of living.A variety of products were combined to achieve the necessary sound reduction throughout the building’s separating floors, ceilings and walls. These included Hush Panel Cem 28, Hush Slab 100 Sound Absorber, Hush Seal 20 perimeter strip, Hush Bond Panel Adhesive, Hush MF Ceiling System and Hush Acoustic Hangers.Through detailed planning from Lioncrest with regard to the schedule, Hush Acoustics were able to deliver all acoustic materials to site ensuring that the deadline for completion was met.

Soundproofing a multi-use residential and commercial building, Ellesmere Port

Soundproofing a multi-use residential and commercial building, Ellesmere Port

Hush Acoustics

Hush Acoustics provided the acoustic floor and wall solutions for a development in Ellesmere Port, Cheshire involving the conversion of a former Woolworths store turned snooker hall, which was being transformed into a ground floor sports shop with nine first floor apartments above. In addition to meeting the acoustic performance requirements, the client was also keen to ensure the design would meet the fire regulations required.Following a site visit, the Hush HD1030 system was specified for the separating floors. This is compliant with UK Building Regulations Approved Document E and is suitable for refurbishment projects with timber structures that incorporate lath and plaster ceilings – all with the benefit of a 1-hour fire resistance at ceiling level.We worked closely with EH Building Contractors to ensure the HD1030 acoustic floor system was installed to the required standard. For the separating walls, Hush Twin Frame Metal Stud Party Walls were installed onto the plywood structural floor and isolated using Heavy-Duty Isolation Tape. The stud walls were insulated using the Hush Slab 100 Sound Absorber, ensuring the cavity between the two stud frames were kept clear.The client had initially discussed keeping the original existing lay in grid ceiling within the shop, however, in order to achieve outstanding acoustic performance, the majority of the perforated metal panels from within the lay in grid ceiling had to be removed. Some of the original ceiling could be retained, however, with higher performing ceiling tiles used to replace it in other areas, maintaining the original features as per the client’s request.Once completed, acoustic testing was carried out on site to determine the success of the acoustic design and installation. First of all, the twin metal stud wall was tested, which achieved an airborne performance of 56db (DnTw+Ctr). An airborne sound test was then conducted between the sports shop and one of the first floor apartments which showed a performance of 47 dB (DnTw+Ctr).All of the acoustic performance goals were achieved without any significant ceiling treatment and our client was happy with the results.

Restoration and Reverberation at Liverpool Central Library

Restoration and Reverberation at Liverpool Central Library

CMS Danskin Acoustics

When American architect, Louis Sullivan, in 1896, said, “Form ever follows function” he probably hadn’t foreseen the creation of the Statutory List of Buildings of Special Architectural or Historic Interest that would have its origins in the devastation left in the wake of the Second World War.The ChallengeThe preservation of old buildings is challenging enough but additional issues arise when it comes to refurbishments and renovations, particularly if there is a material change of use. Suddenly, a building that was created for one purpose is given another, sometimes radically different, purpose. The form can’t follow the function if the function is allocated post-construction. Significant modifications can help align an old building with its new function but, in the case of Grade II listed buildings, for example, the interior can’t be fundamentally changed and function is forced to compromise.Even when there is no significant change of use, modern building regulations demand performance standards that didn’t even exist at the time that buildings currently being renovated were originally envisioned and created. The requirements of Part E of the Building Regulations, governing soundproofing between floors of a building, are relatively easy to shoehorn into a renovation project as these tend to be concealed beneath floor finishes and screeds. Problems with reverberation are far more difficult to tackle and even though there is very little regulation surrounding this issue, BB93 of the Building Regulations, governing reverberation levels in schools, tends to be employed as an effective benchmark.When reverberation levels reach a certain point, they can become more than just an irritation, with the overlap between what is currently being said and what was said a couple of seconds ago becoming genuinely disruptive. In schools, this can make it extremely difficult for children to follow what their teacher is saying. For this reason, BB93 demands a reverberation time of 0.8 seconds or less, with 0.4 seconds being seen as ideal. Reverberation time is described as the time taken for the sound pressure to fall by 60 decibels after the original sound has ceased abruptly. So, in the case of BB93, 0.8 seconds or less after a sound has been made, that sound should have decreased by 60dB. 60dB is a significant drop, the difference between a construction site with pneumatics drills and a busy department store.It is in situations like this, when form and function appear determined to have nothing to do with one another, that architects and the designers of construction materials are driven towards increasingly innovative and paradigm-shifting solutions. The stereotype of the architect who is concerned only with form and is completely disinterested in function is, thankfully, a thing of the past (if these individuals ever really existed at all). Modern architects don’t create buildings so much as living and working spaces, where physical aesthetics are neatly balanced with a host of other concerns, such as the quality of an environment’s acoustics.Although regulation sets crucial, legally-enforceable parameters, few architects need to be incentivised to aim high when it comes to a building’s acoustics.This drive towards innovation has resulted in widely differing solutions. Reflector panels and diffusers redirect sound waves or disburse them more evenly through the listening environment, reducing nuisance noise. These solutions tend to be employed in lecture halls or auditoria, where a certain amount of volume is desirable, but the quality of the sound is crucial. The most commonly employed anti-reverberation product is the sound absorption panel. These fabric covered panels are mounted on the walls of a room or suspended from the ceiling. When the sound wave enters the open cell structure or fibrous composition of the panel, it bounces around like a pinball. The friction resulting from each instance of impact is converted into low-level heat which is absorbed into the material. When the sound wave re-emerges, its energy, and consequently its ‘loudness’, is significantly diminished. This tends to be the solution of choice for classrooms and is generally considered to be the quickest and most cost-effective route to BB93 compliance.Some acoustic challenges are more demanding than others. The renovation of the Picton Reading Room, part of the £50 million redevelopment of Liverpool Central Library, being a case in point. Not only is the reading room contained within a Grade II listed building, it also boasts an elaborate coffered saucer dome. Domes are something of an acoustician’s nightmare, as they focus rather than distribute sound, exacerbating reverberation problems. All of which means a dropped pencil in the Picton Reading Room sounds like a Keith Moon drum solo. Why Cornelius Sherlock, the reading room’s architect, decided to incorporate a dome – one 100 feet in diameter and 56 feet high – into his design for a space that was intended for quiet study is a little bewildering, even if his work does predate Sullivan’s remarks by a couple of decades.Thousands of hours of work have gone into restoring the ceiling of the Picton Reading Room, with plaster, paint and gold leaf being matched as closely as possible to the original 1875 design. Given the need to be true to the form of the original, certain anti-reverberation solutions were unworkable. Reflectors, diffusers and baffles couldn’t be suspended from the ceiling, as all those thousands of hours of work would be hidden from view and the Nineteenth Century aesthetics undermined. Wall-mounted sound absorption panels were not a viable option, as there was very little wall to speak of, with three levels of solid wood bookshelves encircling the room, almost up to the beginning of the dome.Recent innovations in the area of acoustic plaster held the solution. Sound absorbent plaster has been around for some years, offering a smooth appearance which conceals a porous, granular structure similar to that found in sound absorption panels. However, until recently, the amount of sound absorption offered has always been limited to Class ‘B’ and Class ‘C’. Now, however, Class ‘A’ acoustic plaster systems are available. It was just such an acoustic plaster that CMS Danskin used for the Liverpool Central Library project.Because of the limited surface area in the Picton Reading Room, Ellie Morris, CMS Danskin’s Technical Support Coordinator, hit upon the idea of applying the acoustic plaster into the soffits beneath the balconies of the upper shelving areas. The results were a resounding (or un-resounding) success. A relatively small amount of an innovative product, cleverly applied brought a 138-year old listed building’s acoustics in line with contemporary standards and not a hint of compromise in sight.

London Zoo is one of the UK’s best-known tourist attractions and the world’s oldest scientific zoo. Opened in 1838, it now houses nearly 20,000 animals. The new Terrace Restaurant by SHH architects has tripled the dining space to 700 covers. Troldtekt ceilings play a major part in helping to create an acoustically pleasant environment for the high visitor numbers. With an abundance of hard surfaces, coupled with echoes and ambient noise, it was important to find a solution which would complement the design. This has been achieved by installing Troldtekt ultrafine acoustic panels on the ceilings below the mezzanine floor.

Stunning new projects with elegant acoustic design

Stunning new projects with elegant acoustic design

Troldtekt A/S

Danish manufactured Troldtekt panels are commonly specified throughout the UK and Europe to improve the interior acoustic environment. Two recent Danish projects are the transformation of an old building into a car dealer’s offices for Karvil Biler, while the other is an extension of Randers Architects’ own headquarters into a mix of offices and exclusive residential units. Both projects use Troldtekt® line with its perfectly symmetrical vertical lines to balance walls and ceilings with great aesthetics, conveying warmth and providing a modern look coupled with high performance sound absorption.For the Architects’ washrooms, Troldtekt® line was chosen to add visual vibrancy to the rooms. It also exhibits different appearances depending on the angle from which the wall surfaces are viewed. The edges have been milled where the panels meet the ceiling, around electrical sockets and switches and also at floor level where bamboo skirting has been integrated. All have been elegantly cut to ensure a neat finish and fine detailing.In the car dealers, Troldtekt® line was selected in order to enhance and benefit the whole indoor climate. “We wanted to create a coherent look. The milled grooves have a visually calming effect and contrast well with the new raw concrete floor,” the project manager explained. Troldtekt® line forms nine acoustic solutions that make up the “design solutions” range which combines the best ideals of form and function. Founded on the Cradle to Cradle design concept, 100% Troldtekt’s natural wood wool panels are manufactured in a new state-of-the-art production facility. With a variety of different surfaces and colours, they can be supplied in the FSC® 100% category (FSC®C115450) contributing to a building’s BREEAM, DGNB and LEED rating. In addition to their high sound absorption and tactile surface, the panels offer high durability and low cost life cycle performance, as well as inherent sustainability. They are also a natural, breathable material which can absorb and release moisture, which is why they have been awarded an Allergy Friendly Product Award by Allergy UK.

Architectural Beauty combines Form, Function and Aesthetics

Architectural Beauty combines Form, Function and Aesthetics

Troldtekt A/S

There has always been a relationship between design and the marrying up of form, function and aesthetics. While popularity of materials and styles comes and go over the years, how products look, feel and perform is constant. This interesting interplay is explored in the latest online theme from Troldtekt A/S, the Danish manufacturer of acoustic panels. Comprising expert articles, white papers and interviews, the ‘Architectural Beauty’ theme looks at the concept of architectural beauty and the importance of aesthetics in leading certification schemes for sustainable building. It acknowledges that it is not always possible to harmonise the aesthetic with the practical but that there are some ways in which they can be combined to provide value to a building while enhancing its beauty. Australian artist and designer Jay Dee Dearness sums it up well - “Beauty is the melding of functionality and aesthetics in just the right proportions to achieve the desired result.’ Acoustic product manufacturers, such as Troldtekt, embrace this relationship and are at the forefront of practical, aesthetic and high performance products and design. Troldtekt’s wood wool panelling is a perfect canvas allowing architects and designers to realise their most creative schemes, safe in the knowledge that acoustical performance will not be compromised.Since 1903, Copenhagen has presented annual awards for beautiful buildings, landscaping and urban spaces within the city. The Copenhagen Building Award comprises four categories - new buildings, restoration, refurbishment and urban environments. “We present the awards to honour the architects, engineers and developers behind the projects. Also, we’re keen to support projects and urban spaces that are of particular benefit to the city and its citizens”, comments Camilla van Deurs, City Architect of the City of Copenhagen and chair of the building award jury.Copenhagen’s Grøndalsvængets School (pictured), is one of the winning projects chosen by the Copenhagen Building Awards 2020. The school has undergone thorough renovation and expansion, all designed by JJW Arkitekter. It now has a fully modern learning environment where the original qualities have been preserved – and where the indoor climate is exemplary. Like most schools, it used to be noisy by nature from the exuberance of children. Now, this stunning example of architectural beauty shows how large bright spaces, natural daylight and interesting design works well with aesthetic high performance products. It also shows how wood wool acoustic panels make such designs possible while dampening ambient and reverberated noise which would otherwise be unbearable for users.  Many buildings have unique challenges relating to acoustic issues but all can benefit from acoustic panelling to help contribute towards improving the interior environment. Specified throughout the UK and Europe, the benefits of 100% Troldtekt natural wood wool panels include high sound absorption, high durability, natural breathability, low cost life cycle performance and sustainability. Available in various sizes and in four grades from extreme to coarse, the panels can be left untreated or painted in virtually any RAL colour. Samples, case studies and technical information are easily sourced from www.troldtekt.co.uk (tel 01978 664255).

Project: Jodrell BankMain Contractor: Sir Robert McAlpine LtdSubcontractor/installer: Sound Interiors LtdArchitect: HassellProduct: SuperPhonOverall Project Value: £16 millionQuantity: 56 triangular and 26 circular acoustic raftsHassel Architects and Robert McAlpine contractors collaborate on The First Light Pavillion, nestled in the Cheshire countryside at Jodrell Bank. The educational centre with a focus on not only the future of our planet, but of our universe.Jodrell Bank and the First Light PavilionJodrell Bank is the northern heart of British space research thanks to the Lovell telescope, which at 3200 tonnes is one of the world’s largest radio telescopes. The site hosts the yearly science and music festival ‘BlueDot,’ named after one astronomer’s description of planet earth from space as a ‘pale blue dot.’ As the name suggests, the event aims to change the way we think about our planet, with huge mechanical sculptures made of recycled items created each year. It attracts scientists and speakers from around the world, including Brian Cox and Richard Dawkins, award-winning author of ‘The Selfish Gene.’Drawing on the history of Jodrell bank, Manchester University are now embarking on a long term project to introduce a younger generation to science. The team believe ‘A passion for science, sparked in childhood, can be the catalyst that leads to bold new discoveries and a better understanding of the world around us.’ In order to spark this passion, The First Light Pavilion will use immersive installations to tell the history of Jodrell bank and it’s place in science history. The space will accommodate speakers, school trips and conferences, and will bring visitors from all over the UK.Robert McAlpineLead contractor on this project, Robert McAlpine have an equally future facing outlook. They are best known for the internationally recognised Eden Project, an indoor tropical paradise made of a series of interlocking biomes designed to emulate rainforest conditions. Unseen on this scale anywhere else in the world, Robert McAlpine constructed the world largest scaffolding, using 230 miles of poles. As well as looking the part, the offices are also built from entirely recycled materials, and the centre aims to promote caring for our environment. In a similar vein to The First Light Pavilion, the site was specially built to accommodate learning, as well as large scale festivals and events.Hassell ArchitectsHassell Architect’s ethos is focused on science education, winning them two AIA awards for their work with James Cook’s University’s science department. They were highly praised for “making science visible, accessible and attractive,” to both students and the general public. The firm is also known for recognising the changing needs of educational spaces in the digital age. Many of their projects focus on multi-use spaces that can be used for socialising, group learning and conferences. They are based both the UK and Australia, and have led projects everywhere from Brighton to Brisbane, bringing an international flair to the idyllic Jodrell Bank site.CMS Danskin AcousticsCMS Danskin Acoustics describe themselves as experts in soundproofing solutions, and have a huge amount of well known projects to back this up. Many of their most inventive projects have been in partnership with SuperPhon, and showcase CMS Danskin Acoustics ability to create distraction-proof educational environments. Most recently they were involved in a reinvention of Teesside University Library. Tasked with breathing new life into the study space, CMS Danskin Accoustics suspended foam plates from the ceiling to emulate a rainforest retreat. The foam plates were specially designed with study in mind and dispersed sound, keeping interference at a minimum for the students below.The ProblemReverberation is consistently a problem in large educational spaces, affecting sound quality and causing distractions. With 20,000 schoolchildren expected through it’s doors each year, and countless speeches and workshops happening year round, reducing reverberation is of high priority for The First Light Pavilion. A useful measure for the effectiveness of any sound absorption solution is BB93: acoustic design of schools – performance standards. This details the level of sound absorption acceptable for a classroom environment. BB93 recommends reverberation time to be as little as 0.4 seconds, which should be used as the benchmark for this project.The SolutionIn a similar technique used at Teesside University, SuperPhon’s sound absorption rafts will be suspended from the ceiling of the pavilion. They will integrate into the design of the pavilion, as they can be cut to bespoke sizes, mirroring the night sky above. The panels are sound absorbent, made of a composite construction and covered in acoustically transparent woven textile fabric..The ResultReverberation should decrease to 60 decibels in less than half a second, as recommended by the BB93, making The First Light Pavilion the calming educational space it was designed to be. The building will be able to comfortably accommodate thousands of visitors each year with minimal noise disturbances, allowing guests to focus on the majesty of space and the world around us.

A brand new sports complex embodies the functionality and aesthetics of Riga Wood birch plywood

A brand new sports complex embodies the functionality and aesthetics of Riga Wood birch plywood

Riga Wood

Shortly before the new school year started, the municipality of Ogre in Latvia opened a brand new sports complex at Ogre’s gymnasium. In the contest “Sustainability in Architecture Construction Design in the Baltics 2023”, organised by the Building Design and Construction Council, the sports complex was awarded 1st place in the category “Most Sustainable Project”. It was constructed by MONUM construction company.The multifunctional and energy-efficient sports hall has stationary and mobile tribunes, therefore providing space for up to 1700 spectators. The sports complex meets the requirements of the International Athletic Federation with four circular (200 meters) and six sprint tracks, a sector for the long jump, high jump, pole vault, and shot put. Also, in the centre of the hall, there are team sports courts suitable for basketball, floorball, tennis, volleyball and other games. On the second floor, the project's developers have built halls for a gym, gym classes and choreography. The building is complex and multifunctional, and four different Riga Wood birch plywood products have been applied here. Perforated Riga Decor and Riga Lacquer panels ensure excellent acoustics during sports activities, while Riga Paint gives an elegant touch to the lobby. Riga Ply has been used for various construction elements.“Riga Wood birch plywood products were chosen due to two main factors: it is a sustainable, renewable material with excellent technical properties and durable, with high wear resistance. Furthermore, in sports halls it is important to ensure good acoustics and perforated acoustic panels made of Riga Wood birch plywood panels serve their duty perfectly,” comments Maksims Žaguļins, project manager at MONUM.Riga Wood birch plywood has a long lifespan, and what is no less important, the maintenance is easy too. “In recent years, birch plywood has been used in many sports halls, especially for acoustic panels. The technologies that we use allow us to adjust the panels to the specific needs of each project with great results”, comments Intars Metums, head of the Wholesale Department of Riga Wood Baltics. “Furthermore, the versatility in our Riga Wood birch plywood products allows us to find the best solution, whether it’s for wall lining, floors or tribunes,” adds Intars.

Hush Acoustics

This project involved providing a soundproofing solution for a Grade ll listed period building located in the south west of Sheffield, close to the botanical gardens, where the former NHS building was undergoing conversion into residential wellings.Hush were involved in the very early design stages of this conversion/new build project and under direction of our client Jonathan Frith of Bamford Homes. We also worked alongside acoustic consultants HRS Services Ltd (now Stroma Specialist Access) and architect Richard Keighley from DKMY Architects.A variety of Hush Systems were specified to deliver excellent acoustic performance.HD1030: Hush System LP was applied to the ground and first floors. This is a floating floor system, compliant with Building Regulations Approved Document E, used in refurbishment of timber floors. It also holds 1-hour fire resistance at ceiling level.HD1032: Hush System LP/MF was used from the second to first floor and from the third to second floor. This economical sound insulation system for use between separating floors is made up of Hush Panel 28, Hush Seal 20 and Hush absorber slabs. It is used within refurbishment projects using timber joists and also provides 1-hour fire resistance at ceiling level.Along with using these systems, we also upgraded the existing walls using our HD1040: Wall System which provides high standards of airborne sound reduction and can be used to reduce both flanking and direct sound transmission. It again is compliant with UK Building Regulations and provides a minimum loss of space within rooms.Within the new build residential space, we recommended our HD1054: Double Timber Stud Wall System which is our extremely effective system comprising of Hush Slab absorber slabs and Acoustic Plasterboard.Although design stages through to completion of this project were around 3 years, the conversion and new build project itself, once begun took around 18 months. All acoustic testing carried out on site was passed.The flats are in a sought-after area, close to the University of Sheffield and Hallamshire Hospital, within easy access to facilities in Broomshill and Eccleshall road and have been finished to a high acoustic standard.

Solving reverberation issues in classroom at Bird in Bush Primary School

Solving reverberation issues in classroom at Bird in Bush Primary School

Hush Acoustics

The merger of two primary schools in south London meant one of the school buildings would be retaining and upgraded to facilitate the combined 380+ students in the 3-11 age range.The newly formed Bird in Bush Primary School is Southwark’s newest school, which has been adapted to accommodate an increased number of children to ensure their needs are met, and that the learning environment is inclusive for all.One of the ways the school was adapted prior to opening for the autumn term was to create the right acoustic conditions inside one of the classrooms for a student with special educational needs (SEN), who was moving from Coburg School. The child’s condition meant that they were more susceptible to the adverse effects of noise resulting from reverberation and echo, which could potentially have an impact on their learning outcomes.The child’s parents felt this was a particularly important issue to address given that their child was entering Year 6, which they believed would be more significant than previous school years and more stressful. The acoustic treatment deployed involved the installation of Hush Absorber 50 sound absorber panels. These products were previously installed in the school's large dining hall to reduce high levels of background noise and echo.The aim was to calculate the current reverberation time (RT), the time taken for the sound pressure level from the original sound to drop by 60dB after it stops, and work out how much absorption would be needed to bring this in line with the requirements of BB93.The solution provided by Hush involved the manufacture and installation of 40x Hush Absorber 50 panels, which were sized 1200 x 600 x 50mm and covered in a fabric coloured in a neutral tone to blend seamlessly with the classroom’s main colour. These were fitted onto the soffit of the classroom’s sloping ceiling which was important to ensure the walls could continue to be used for notice boards and other displays.Prior to their installation, the RT was measured at 3.8s and following the upgrade the reduction in reverberation is evident in the fact that this figure is now 0.8s. This was the lowest figure possible given the available space for the sound absorber panels on the soffit.Disruption to teaching was completely avoided because the Hush Absorber 50 panels were fitted in just one day during the summer holiday closure of the school.

The product selected for the project was the Soundis Absorb-R GypLine αw (also commonly known as a Seamless Monolithic Acoustic Spray Plaster System) which is an extremely flexible seamless sound absorption system. It is a non-perforated, monolithic system consisting of a mineral fibre panel with a layer of micro-porous plaster. Excellent Sound Absorption was required at this project and therefore our task was to ensure class A sound absorption within the large atrium. The Absorb-R GypLine αw was used as a seamless high performing sound-absorbing system, a system with excellent eco-credentials. The GypLine αw insulation board also benefits the energy performance of any building by enhancing the insulation of the building envelope.We were challenged with working almost 20 meters above the floor which adds difficulties to any installation but nothing we haven’t overcome before in previous projects. Absorb-R GypLine αw was selected as the finish offers unrivalled levels of sound absorption but also ensures walls and ceilings are clear of panels and visible acoustic solutions, providing a virtually seamless monolithic surface for walls and ceilings in a choice of RAL colours. This seamless and complete solution can be adapted to a wide range of rooms, from home use, office space to conference halls, auditoria, theatres, recreational sports and educational areas. The Absorb-R GypLine αw acoustic system is environment-friendly, fully recyclable and has natural components that offer optimal sound absorption with extensive resistance to fire.

World-class concert acoustics

World-class concert acoustics

GKD - GEBR. KUFFERATH AG

The Koningin Elisabethzaal in the northern Belgian seaport of Antwerp is unusual in every respect. Located at the heart of an architecturally charming city, structurally merged with a world-famous zoo, and boasting an immensely varied history as a concert hall, it transformed from an acoustic ugly duckling into a gleaming swan of aural experience. At the core of this metamorphosis is the design by the renowned American acoustician Larry Kirkegaard, who completely remodeled the hall acoustically. Golden metal fabric by GKD – GEBR. KUFFERATH AG (GKD) plays a key role in his concept. The woven texture really underlines the one-of-a-kind spatial experience in its use as large-scale cladding for ceiling, walls, and balustrades.One of 65 participants in an international competition to redesign and remodel the Koningin Elisabethzaal, the consortium comprised of SimpsonHaugh Architects (London) and Kirkegaard Associates (Chicago) produced the winning design. Kirkegaard’s ambitious concept, which employed structural and technical agility to aim for nothing less than a world-class standard for the new concert hall, played no small part in this success. The original hall was opened in 1897, served as a hospital ward during the First World War, morphed into a venue for boxing and wrestling matches during the Olympic Games a few years later, and was reopened in 1960 following major destruction in the Second World War. The fan-shaped design of this building, which was not intended to be used purely as a concert hall, contributed greatly to its poor acoustics, which achieved only six out of ten points on the rating scale. Plus, although it provided a stage, there were no rehearsal rooms for the orchestra and soloists. One aim of the new building was therefore to finally offer a home to the Antwerp Symphony Orchestra. The new Koningin Elisabethzaal is the centerpiece of the Elisabeth Center, which was also newly built as an ultramodern 25,000-square-meter conference center. When redesigning the concert hall, the planners decided to reduce its size in order to optimize the acoustics. This resulted in an enormous light-flooded foyer with atrium in the Elisabeth Center. Architect Ian Simpson embedded the new building into the historical complex in such a way that the art nouveau façades that had previously been hidden by the building were revealed once more and the old halls remained largely untouched. One of these halls, the Loos Hall, connects the new 2,000-square-meter concert hall with the historical part and also serves as the foyer of the Elisabeth Center. With its high stuccoed ceilings and rich marble decor, it provides a representative space for exhibitions and receptions. The new four-story building comprises various conference and meeting rooms for up to 1,900 participants, the concert hall with a capacity of 2,000 guests, extensive logistics facilities, VIP and catering areas, administrative offices, and soundproofed rehearsal rooms.An acoustic embrace in a shoe boxThe designers selected a shoe box shape for the concert hall, which classical music lovers deem to be a guarantee of optimum acoustics. This is aided by a perfectly balanced distance between the stage and the wall and an unusual seating arrangement in the parterre and the two galleries. Doing without a permanent apron also prevents a loss of sound. A curved wall means that the largest distance between the stage and audience seats is 30 meters, so that every guest feels part of what is happening on stage and can see and hear equally well from all seats. Movable reflectors clad in metal fabric and suspended from the ceiling as well as frames covered in the same fabric ensure that the sound is able to unfold throughout the entire hall. At the same time, the semitransparent membranes conceal the bare ceiling and the technical installations above. In designing the walls, Kirkegaard Associates chose a wave-shaped oak wainscoting. The cavities were filled with lava sand to prevent vibrations. With this construction, the acousticians drew on the sound experience of earlier concert halls, which employed arm-thick stone walls to reflect low-frequency sound back into the hall. As such, the walls and the rear wall of the stage in the Koningin Elisabethzaal form an acoustic embrace which ensures that the echo is not absorbed but is fully reflected to the stage.Metal fabric for good soundThe same fabric that was used for the ceiling elements also covers the movable reflectors on the back wall of the stage: gold-colored powder-coated Alu 6010. For the ceiling and stage wall, GKD fitted a total of 204 frames, some of them wave-shaped, with 1,600 square meters of this fabric type. Four-meter-long and 2.50-meter-wide panels were fastened to the frames provided by the customer with thin stainless steel wires at intervals of ten centimeters. GKD also incorporated the cutouts for the lights exactly according to the specifications. A first for the weave specialists was that the entire construction consisting of frames and fabric was then coated in the desired shade of gold. This required special pretreatment in order to ensure homogeneous coloring of the components made from different materials – steel and aluminum. Prior to selecting the material, Kirkegaard Associates had carried out extensive tests on the GKD fabrics in order to achieve the best possible sound and space experience. As such, GKD was involved in the planning process with architects and acousticians from a very early stage. The decisive factor in opting for metal fabric was the acoustic neutrality. In addition, the exclusive look, flexibility, and robustness of the GKD fabrics corresponded to the ambitious design concept. That is why the fabric from GKD – Omega 1520 with gold-colored coated weft – was also chosen for the balustrades of the galleries. It fits flexibly to the bidirectionally curved corners of the balustrade and is also resistant to impact thanks to tensioning in the direction of the cable. When fitting the front and rear of the balustrade elements with 400 square meters of this fabric type, the curve needed to be followed exactly. GKD selected a slightly conical panel cut for this purpose in order to realize the radius by tracing a polygon.The clever interaction between the design of the hall shape, ceiling, wall, and balustrade is what gives the new Koningin Elisabethzaal its excellent acoustics: with 9.3 out of 10 points on the rating scale, it is considered almost perfect. At the opening concert, Belgium’s Queen Mathilde personally handed over the hall, which offers a world-class space and sound experience, to the public.
