Acoustic management is something very few people aware of. The properties of sound differ substantially depending on the frequency range. Sound can be divided into infrasound, audible sound and ultrasound. The science of acoustic management begins with reverberation times, which are the parameters used to objectively describe the echoic quality of a room. Long reverberation times will cause sound waves to be prolonged and echoes are created.
The more reverberant a room, the more people will raise their voices to compensate for the increased noise level to make themselves heard over the background noise. This only compounds the problem and makes for a very unpleasant environment.
Most people accept noise as normal without being aware there are reasonable acoustic solutions and sound control strategies to manage the problem. To correct these problems consideration needs to be given to the shape, size and volume of the area, the surfaces finishes, the type of activities, the sound system and the budget. Acoustic materials are used for reducing the noise. Let’s take a look at them-
- Diffusors
Diffusors are used in areas with flat ceilings or parallel walls to stop or reduce sound echoes that can occur.
- Absorbers
Midrange and high frequency absorbers are acoustic materials that absorb any frequency above 500 hertz. Absorbers, like diffusers, reduce ringing and echoing but they also reduce the reverberation time of a room.
- Bass Traps
These acoustic materials reduce the reverb time in larger spaces like churches, auditoriums and large recording studios.
Property developers are now getting requests from their clients for the properties with proper acoustic management. Property acoustic systems are readily available which can be incorporated as wall or ceiling linings into any project design. Used correctly, these will assist in bringing down reverberation times to the recommended levels for a range of project types. Proper sound control acoustics need to be introduced to reduce the noise level.
