Control of

Interfering Noise

here are four basic approaches to reducing noise in a listening room
Tor a recording studio:
Locating the room in a quiet place

Reducing the noise energy within the room
Reducing the noise output of the offending source
Interposing an insulating barrier between the noise and the
room

Locating a sound-sensitive area away from outside interfering
sounds is a luxury few can enjoy because of the many factors (other
than acoustical) involved in site selection. If the site is a listening
room, which is part of a residence, due consideration must be given
to serving the other needs of the family—at least if some degree of
peace is to prevail. If the room in question is a recording or broadcast
studio, it is probably a part of a multipurpose complex and the noises
originating from business machines, air conditioning equipment, or
foot traffic within the same building, or even sounds from other stu-
dios, may dominate the situation.
