It is very common to find high levels of reflected sound in buildings. This makes it difficult to hear people speaking because it generates high levels of background noise when lots of other people are talking in the room. The solution is to install a specialist type of acoustic ceiling panel or wall tile to control and absorb some of the sound. This acoustic treatment can greatly reduce the level of reflected noise and considerably improve the acoustics of the room, making communication much easier. This acoustic solution can be applied wherever reflected or reverberation noise is a problem, including offices, canteens, colleges, schools, restaurants, student lounges, computer rooms, industrial offices and factory control rooms.
The type of acoustic panel, its material, size, location and area of coverage are all critical in achieving the optimum sound conditions and the best acoustic solution. We can assess all these factors and determine the optimum acoustic treatment and panel for any type of room or building.
We normally use a type of acoustic panel that provides a particularly high noise reduction. In previous projects this has proved very successful, and our acoustic solutions have achieved very high noise reductions.
We were asked to help with acoustic treatment for a control room in a flour milling machine area of a factory. The milling machines were generating high noise levels in the adjacent control room and this was causing complaints from workers. We installed high performance acoustic panels in the ceiling of the control room and also sealed some gaps in the walls. This produced a 6 - 7 dBA noise reduction inside the control room. The acoustic ceiling panels transformed the room acoustics and produced a huge improvement in the subjective impression of the noise. After installation, workers said they were very pleased at how effective the acoustic solution was and they were pleasantly surprised at how much quieter the milling machine noise was.
At Cheam independent school near Newbury, Berks (Berkshire), high levels of reflected noise made communication difficult in a dance and drama studio, resulting in complaints from the teacher about the room acoustics and the amount of echo. We determined the optimum type of acoustic panel, its thickness, location and coverage area. The result was a specialist type of acoustic absorber panel fitted to the ceiling (none were needed on the wall areas). This achieved a very large reduction in the reflected sound, greatly reducing the background noise from children talking / performing, and making it much easier for the teacher to make herself heard and to control the class. There have been no more complaints since installation of this acoustic solution.
Soundproof acoustic door seals were also fitted to the double entrance doors to reduce the noise transmitted into the drama / dance studio from the school sports hall below. The combination of this plus acoustic treatment for the studio ceiling achieved a very large noise reduction.
A college asked us to help improve acoustic conditions within a student lounge, canteen and in a large open-plan room where software apps are written / developed. In the lounge and canteen, sound levels from people talking were very high and this made it difficult to communicate and made for a very unpleasant acoustic environment. The computer room was subdivided into several smaller areas with office screens. Although sound levels in this room were low compared with the lounge and canteen, they were still loud enough to disturb concentration and impair productivity.
We calculated the existing reverberation times in the rooms - this is a measure of current acoustic conditions. We then assessed a range of different acoustic solutions, treatment and products to determine the best option in terms of sound reduction and cost. The acoustic material, coverage area and location were selected to achieve acceptable acoustic conditions (reverberation times) for the activity that occurs in each room.
For acoustic solutions to be effective, it is very important to install the optimum amount of acoustic absorbent material, and to apply it to the most appropriate surface (usually the ceiling, wall or both). It is also very important to match the acoustic solution to the type of activity that occurs in the room.
There is a delicate balancing act. If too little acoustic material is installed, or if it is not installed in the best location(s), reflected noise will still be too high. Then, the background noise will remain too high and communication will remain difficult. If too much acoustic material is installed, there can be too little reflected sound and, where the room is used for presentations, the speaker may need to shout to be heard at the back of the room. So, obtaining specialist advice from an independent expert can be invaluable in ensuring satisfactory acoustic solutions. We can provide that advice - we take great care to get the balance right.
We aim to provide optimum acoustic solutions in terms of both performance and cost. Our company prides itself in achieving highly effective sound control solutions at reasonable cost.
