Hi Folks,

Have you ever experienced or seen Active Noise Cancellation or Control in HVAC ducts? I have read articles about the system but have never seen this system being used in HVAC ducts. It is effective to diminish sound with low frequencies up to 500Hz. By this way, this is very effective for absorbing unwanted noise sourced from fan (having high sound power level in low frequencies)

Regards,
Emre
