Ceilings and architectural metalwork can play an important part in meeting the standards required for high quality acoustics in modern building design. An example of this is Health and Technical Memorandum 2045 published by NHS Estates, which sets out the acoustic performance criteria for sound insulation and absorption within hospitals. SAS International is an expert in acoustics, designing products and solutions that improve acoustics in new and refurbished buildings, whilst also offering additional performance benefits. Our metal ceilings, room comfort and architectural metalwork solutions, such as acoustic lighting rafts, wall panels and acoustic baffles, have been developed to help ensure optimum acoustic performance and meet the standards and procedures laid down in BS EN ISO 11654:1997, BS EN ISO 140 and BS EN ISO 117. Our interiors solutions provide improved sound absorption, to reduce the overall noise within a space, and improved sound attenuation, reducing the movement of sound between spaces such as lecture theatres, corridors, offices, classrooms and public buildings. Our suspended ceilings absorb the passage of sound waves through the perforated face of the ceiling tile which then interacts with the material within the back of the tile. Active measures such as acoustic attenuators can be designed to meet the exact requirements and specifications of an environment. A series of acoustic baffles can be suspended vertically or horizontally to reduce cross-talk attenuation and improve acoustic absorption. These are suitable for a range of environments however especially so in educational environments, which are subject to the Building Regulations. Building Bulletin 93: Acoustic Design of Schools. There are various standards that deal with acoustics including BS EN ISO 11654:1997, which provides for five categories of sound absorption ranging from Class A to Class E, as well as guidance from organisations such as The British Council for Offices. Through our solutions based approach we work with our customers technical and design project teams to consider how best to approach acoustics and to help them meet the required standards. |
