Acoustic Ready-to-Assemble Anechoic Chamber

Ready-to-Assemble Anechoic Chamber

The Anechoic Chamber uses the “non-flammable wedge-shaped absorbers” which we newly developed.  Through conventional methods we could not realized.  But “Non-flammable”, “Non-sound reflex materials”, “High soundproof capability”, and “ low price” are now available.  Because by using our new material Metal Panel with several layers helps to relocate our Anechoic Chamber easily at any place.
No more “wood work” or “ concrete construction”.
