acoustic wall panels & diffusers
After we have built a specialist acoustic environment, space-pod can fine tune the space utilising acoustic absorption or diffusion panels and bass traps to ensure the room performs correctly.
So how do we do it?
Sound within a room is a combination of direct sound emitted from the source and indirect sound reflecting off hard surfaces within the room. Sound waves travel through the air until they reach a surface or obstacle which, when it hits the surface, will be partly reflected off the wall and back into the room and partly absorbed by the surface.
Some reflected sounds are desirable in an acoustic environment, however too much reflected sound can cause echo and reverberation. The reverberation time in a room is the time it takes for the sound to decay by 60dB. If the reverberation time is too long it makes speech very difficult to understand and more difficult to communicate or record effectively. If the reverberation time is too short then the room can sound lifeless.
Most reverberation problems occur in rooms constructed with acoustically hard parallel surfaces where flutter echo can occur, significantly increasing reverberation time. The most common method of dealing with echo and reverberation problems is to absorb them by applying porous materials to the internal surfaces.
Space-pod use acoustic wall panels and diffusers to provide the correct acoustic climate in a room. The choice of surface is dependent on its acoustic efficiency, appearance and durability. By converting sound energy into heat, these surfaces can also help sound insulation as less noise will be transferred to other rooms.
Wall diffusers are used to disperse incoming sound waves and are usually constructed with a complex surface to allow the incoming sound wave to be scattered away in many different directions (diffusion) resulting in standing wave and flutter echo reduction. By utilising both absorbent panels and diffusers, an optimal acoustic performance is achieved; speech intelligibility is improved and an overall ambient sound is still present.
Bass traps are acoustic energy absorbers used to dampen low frequency sound energy in order to produce a flatter low frequency room response. There are generally two types of bass traps: resonating absorbers and porous absorbers and they are usually installed in the corners of rooms. Space-pod utilise both types of bass trap depending on the application required for the project.
So there you have it, a beginner’s guide to how acoustic tuning works and how we apply it.
