IAC made single-walled booths with 8" thick walls for a while (as opposed to the 4" used in both single-walled rooms and double-up in double-walled rooms). Since they were custom, they don't have a model number I can use to search for their sound-attenuating characteristics. Does anyone know the attenuation properties of these rooms?
Thanks, David Smith
