Electronic Bass Trap

Document Thumbnail

Bass traps, regardless of their effectiveness in abating bass acoustic coloration in a room have two, somewhat undesirable attributes: 1) large size and 2) lack of adaptability. An alternative to the use of bass traps, discussed in this paper, is incorporating a properly devised, feedback control scheme into a powered subwoofer making the subwoofer to exhibit the same dynamics as that of a bass trap. This patent pending, active coloration control solution which can be viewed as an' electronic bass trap 'adds acoustic damping to the low-frequency modes of a room. In addition to a powered subwoofer, the electronic bass trap uses a microphone and an op-amp circuit. Numerical and experimental results indicate the effectiveness of the electronic bass trap in adding acoustic damping to the low-frequency standing wave (s) in a room.
