The invention converts non audio systems into distributed audio sources
for active noise control solutions. The system transforms non acoustic
structures into soundboards using inertial type acoustic transducers.
Acoustic parameters unique for each application due to the variation in
properties of the sound board are compensated by equalizers. The
invention also uses damping means to limit the reflection of bending
waves from the edges. The inertial type acoustic transducer is driven by
an amplifier. The acoustic signal to the amplifier is modified by a
signal conditioner to compensate for the non optimal response of the
acoustic system. An external controller communicates with the amplifier
to control its operating parameters. A series of distributed audio
sources in a variety of positions may each be addressable as a node on a
network wherein noise detected at that source is analyzed and the system
generates sound at that source to mask the noise.
