It’s remarkable technology that perform so well you think it breaks the laws of physics. There’s nothing else on the planet that comes close to the performance of this patented technology! - Bob Katz
What does AVAA stand for?
Active Velocity Acoustic Absorber
How does it work?
What does the AVAA not do?
The AVAA is a solution for room modes below 120 Hz and absorbs low frequencies only. The AVAA will not absorb frequencies above approximately 150 Hz. It is therefore not a total solution for acoustically bad rooms. For best results, it needs to be combined with passive absorption in higher frequencies.
What effect will the AVAA have in my room?
The AVAA will have the same effect, on frequencies from 15 to 120 Hz, as opening a window about 5 to 10 times the size of the AVAA. This will impact sound in the time, frequency and space dimensions.
How many AVAAs do I need?
An acoustician will be able to compute the effect of a certain number of AVAAs in a particular room.
Depending on the dimension and type of room as well as the result required, between 2 and 8 AVAAs are necessary. For very small rooms a minimum of two AVAAs is recommended to have a symmetrical effect. For most normal size rooms (between 20 and 80 m2) it is recommended to use 4 AVAAs and for larger rooms the number can be increased to 6 or 8.
Note that this technology has several international patents pending.
