PSI Audio | AVAA C20 - Active Velocity Acoustic Absorber (bass-trap)

Active Velocity Acoustic Absorber

The AVAA is designed to absorb the standing modes between 15 and 150 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.

100% ANALOG, no DSP, no latency  Effective as perfect absorber up to 25 times its size  No calibration or settings are required  No sound emitted and no alteration of the sound source  2 AVAAs will make a significant difference in normal sized studios  Works in any type of room: recording, mixing, mastering, listening…

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. It is important to work on the positioning of loudspeakers and listening, as the AVAA will have little effect on inevitable first reflections.

The AVAA will have the same effect, on frequencies from 15 to 150 Hz, as opening a window about 5 to 20 times the size of the AVAA. This will impact sound in the time, frequency and space dimensions.

  • Time: it will significantly reduce reverberation time in these frequencies especially on room modes.
  • Frequency: with more precise and tighter bass, the masking effect of higher frequencies is reduced. Details in higher frequencies also become clearer.
  • Space: with less indirect sound in the room, the location of the sound is more accurate making the sound image more precise.

Different Types of Applications :

  • Recording, mixing and mastering studios
  • Home studios
  • Home cinemas
  • Small clubs
  • Bars
  • Boiler / machine rooms
  • Industrial facilities
