How do you control sound?

Controlling stress and silence.





Reverberations are a problem. How do we address them?


We've talked about reverberations before.Simply put,they're reflected sound waves.

Reverberations can reduce speech intelligibility, create background noise and disturb room occupants.










When you're treating a room, you can absorb, block, cover or diffuse

That's a lot of solutions. We'll go through them all.







Absorb

Sound can be captured by absorbing materials, like these.
These materials can help you absorb sound by placing them in walls, ceilings, floors, furnishing and pretty much every place in a room.
Absorption is useful, but it doesn’t solve all your problems.
Sometimes, reverberation is useful, and absorption just gets in the way.
If you’re trying to reduce the transmission of sound to other places, what you need to do is block the sound




Block

Blocking means that you want to avoid sound transmission to a certain room or area.
Blocking the sound works by using materials with low transmission in walls, ceilings, partitions, and even high furniture.
Or you can isolate a specific sound source, like you do with an acoustic cabin.




Cover

Sound can be covered or masked by introducing additional sounds to a space
. If voices are incredibly distracting for a space, you can introduce white noise so that you can’t hear people talking.




Diffuse

Diffusion is useful for places where sound is incredibly important, like studios or cinemas.
The idea behind this is that you can create better sounding rooms if you control where and when the sound waves are present.
Diffusers allow you to do this by controlling sound directions, stopping it from being directly reflected, which causes excessive reverberation.
Sound can be diffused or scattered in different directions when you use materials with textured or uneven surfaces, like these ones.
Different depths will address different frequencies, so a diffuser with various heights is a better diffuser than one without them.
