Active Sound and Vibration Control (ASVAC) |
-
electronic system that cancel disturbing noise in
confined environments by creating an antinoise signal
-
improves
acoustical environments
-
control
low frequency noise (less than 700 Hz) in Heating, Ventilation and Air
Conditioning (HVAC) systems, in ducts carrying corrosive or high
temperature fluids (like car engines, air compressor exhausts or hydraulic
circuits) and heavy vehicle and airplane cabins
-
often used in concert with conventional
dissipative
|
|
Features:
An active control system consist
of:
-
an input
microphone upstream to measure noise
-
a
processor to analyse the noise and generate a contrary sound wave
-
a system
composed of an amplifier and loudspeakers
-
and an
error microphone downstream from the loudspeakers to pick up residual
noise and signal the processor to adjust the antinoise signal
|
Applications:
-
attenuation of noise generated by rotating machine (roots exhauster,
vacuum pump, diesel engine…)
-
ventilation system, compressor air intake, exhaust
of generator, diesel engine, vacuum pump enclosure…
