We design, manufacturer and installl all types of Anechoic Chambers which precise the specifications for many industries and fit to required applications. 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.

 

ANECHOIC CHAMBER DESIGN

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.


INDUSTRY APPLICATIONS

we designe anechoic chambers for the applications that require precision-level acoustic measurements need to optimize product design and performance of Loudspeakers, Microphones , Cell Phones , Information Technology Equipment , Automobile Components.
