An "isolation booth" is a standard small room in a recording studio, which is both soundproofed to keep out external sounds and keep in the internal sounds, and like all the other recording rooms in sound industry, it is designed for having a lesser amount of diffused reflections from walls to make a good sounding room. A drummer, vocalist, or guitar speaker cabinet, along with microphones, is acoustically isolated in the room. A professional recording studio has a "control room", a large "live room", and one or more small "isolation booths".
