Anechoic Chambers are echo-free enclosures with a sound energy absorption level of 99% to 100%, or a reflected soundpressure level of 10% or less. The frequency at which the energy absorption drops below 99%, or the pressure reflection exceeds 10%, is known as the low-frequency cut-off.
A full Anechoic Chamber is an acoustical structure that simulate "free field" conditions, where the walls, floor or ceiling absorb 99% to 100% of the incident sound energy. These chambers are constructed with noise attenuating outer structures of masonry or modular panels and have all interior surfaces lined with anechoic wedges.
They have working floors constructed of spring tension cable mesh or grating floor sections to support heavy test specimens above the floor wedges.
Hemi-Anechoic Chambers
Hemi-Anechoic Chambers have acoustical treatment on the walls and ceiling only and feature hard floors with no acoustical treatment. The solid floor of the hemi-anechoic chamber is common for testing large and heavy equipment.
The below Hemi Anechoic Chamber was recently constructed for the Cyprus University of Technology (TEPAK). As far as we know, this is the only Anechoic Chamber available in the Eastern Mediterranean region.
