Trap Small rooms like studios, garages, home sound systems, need a very efficient surface to diffuse interfering rear wall reflections and provide a diffuse sound field. Specular reflections from flat, hard surfaces cause strong reflections that corrupt speech intelligibility and degrade sound quality. However, the corners between two walls and a wall and ceiling, usually go unused. The cavity supporting the membrane is molded into a trapezoidal shape to fit in these 90 corners. The 2' x 2' face is upholstered with Guilford fabric for a handsome appearance.
Traps function best when placed in the middle of standing waves.
When sound excites the air in a room, that air takes on standing wave patterns defined by the room's dimensions. To find this wave, play music with heavy bass content. Carry a B.A.S.S. Trap around the room to determine where the traps vibrate the most. The vibration is an indication that the trap is working. Locations that cause the most vibration of the traps are where they will be most effective.
