QuietStar recently installed a bespoke double acoustic doorset at Glyntaff…
The main anechoic testing chamber was the priority for this project. Will Pryke (Digitech Centre Project Manager) at the University of Suffolk outlined some big plans for the facility – “the main usage of this fully anechoic chamber will be to further develop our creative arts and digital communications courses. We’ll teach students how to use the chambers and how they can be used for research and development. We will also look to make the facilities available externally to the business community”.
The team at QuietStar completely stripped out and disposed of the existing foam wedges and steel ‘weldmesh’ grid support frames, speaker support frames, cable floor support system and corner flood lighting. These were replaced with new fire rated foam wedges and support frames, an acoustically transparent catch net below the old cable floor, new speaker support mounts, new door seals, new electrics and diffused lighting.
The second anechoic chamber was a smaller 250hz full anechoic chamber, also in a concrete shell. The refurbishment of this chamber was less extensive to reduce costs. We replaced some of the wall and door wedges as well as the door seals and lighting.
This anechoic chamber was also independently tested, and it was shown to have a cut-off frequency of 200Hz (limited by the physical room dimensions) and a background noise level of 8dBA: suitable for sound power level measurements, free-field sound field audiometry and hearing protector testing
Before and After Photos Of The Small Anechoic Chamber:
The old foam in the Min-Anechoic Box was so degraded that it was unable to perform acoustically. We replaced the foam with high quality, durable foam to bring it back to life.
Reverberation rooms can be thought of as the opposite of anechoic chambers; instead of absorbing sound, the walls, floor and ceiling reflect sound energy. With multiple testing uses, the existing, outdated room was brought in line with the other refurbished rooms.
The main changes were to door seals and lighting, but we also repainted the ceiling, walls and floor to cosmetically bring the facility up to date with the other refurbishments.
