Key factors to consider in the implementation of acoustic control in recording studios include:
Room size and shape
Need for sound isolation
Dual purpose rooms requiring variable acoustics
Live Room. This is the room that has all the sound happening in it, from acoustical instruments, to vocalists. Ideally you want to have this room as isolated from outside sound invasion.
Treating the acoustics within the room primarily rests on the shape of the room itself. If you are building this from scratch, a great thing to do is to make sure none of the walls are offset 90 degrees from each other. We want to minimize the ability for sound to bounce back and forth between opposing surfaces giving a flutter echo.
Walls should be offset as much as possible. Another aspect is to make sure the length, width, and the height of the room are not all multiples of each other – that’s a great way to mess up the modes of the room. If you are retrofitting a room, then you don’t need to re-engineer your walls, but you are either going to want to deaden them out completely, or make them diffusive.
Making the Live Room diffusive. Diffusers require a higher investment than absorptive panels. But, absorptive panels make the room sound deader, where diffusers make the room sound better. Large diffusers like Pyramid and Barrel diffusers aren’t that great for small rooms, they are more for large band rooms The more of them you get, the better the room sounds.
Production / Recording room. This is the room you will be listening to the music in, and you need to hear what it’s going to sound like in any given room and through a real set of speakers. Diffusion is critical in these applications.
