PSI Audio AVAA C20 Active Velocity Acoustic Absorber
The AVAA is designed to absorb the standing modes between 15 and 120 Hz in a room. It will do so just like passive absorbers but in a much more efficient way and using up much less space. Each operating AVAA will have the same effect as a hole in the wall much larger than the dimensions of the AVAA (that is 0.2 m2). The exact ratio will depend on the frequency and environment but typically range between 5 and 20.

The AVAA will affect the impedance of the air and “suck” low frequencies around it.

Therefore the best position to place an AVAA is in the most rigid corners as that is where all room modes will be most present.

How does it work?

Note that this technology has several international patents pending.
A microphone will measure the acoustic pressure in front of an acoustic resistance.
The acoustic resistance is designed to let air through but reducing significantly the pressure.
A transducer membrane is driven to absorb the volume of air going through the acoustic resistance.
This significantly reduced the acoustic pressure (between 15 and 120 Hz) around the microphone and around the AVAA.
