About BRD HUSH POD™ Mufflers:
 

HUSH POD™ electronic cancellation silencers utilize the principle of destructive interference to reduce noise levels on open pipe systems such as vacuum blower outlets, pressure blower intakes and internal combustion engine exhausts.  A microphone records the noise source sending a signal back to the control box/amplifier which generates a 180° out of phase equal and opposite "anti-noise" wave amplified through speakers mounted in a single housing.  The speakers are not directly exposed to the air flow.  Cancellation takes place at the end of the open pipe.  HUSH POD™ active mufflers provide maximum noise reduction in the 50 to 500 Hz frequency range where traditional passive designs are lacking.
