Low frequency acoustic absorption

Low frequency acoustic absorption

Published:

PSI Audio describes its AVAA (Active Velocity Acoustic Absorber) as an ‘anti-wall’, as it is designed to neutralise a wall’s negative reflective effects. Its purpose is to absorb the standing waves of up to 150Hz, controlling a room’s low frequencies. Being an ‘active absorber’ means that that the system is more efficient while taking up less space, states the manufacturer.

Each AVAA unit will reportedly produce the effect of a hole in the wall between five and 20 times its size. The device is said to emit no sound and to not require any calibration or setting. It is designed for portability and can be used in any type of room, including recording facilities.
