FULL ANECHOIC CHAMBER
Full Anechoic Chamber is a specific type of room which is completely free from sound reverberation. And any sound projected into the room, at any frequency, is fully absorbed.
Full Anechoic Chambers are engineered acoustical structures 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.
Full anechoic chambers have working floors constructed of spring tension cable mesh or grating floor sections to support heavy test specimens above the floor wedges.This is basically designed to suppress the internal sound reflections and used for acoustical measurements.
The effectiveness of an anechoic chamber is measured in dB of rejection, which is the ratio of direct sound to reflected sound inside the room. Our designed Engine test anechoic chamber provides better than 80dB rejection from 20 kHz down to 80Hz, which is excellent in term of performance for a medium-sized chamber.
