These chambers are constructed with noise attenuating outer structures of modular panels and have all interior surfaces lined with PU wedges Foam.This has working floors constructed with 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 anechoic chamber provides better than 80dB rejection from 20 kHz down to 80H.
