Standard product for Soundproof
/ Acoustic Ready-to-Assemble Anechoic Chamber

@


+The Anechoic Chamber uses the gnon-flammable wedge-shaped absorbersh which we newly developed.
Through conventional methods we could not realized.
But gNon-flammableh, gNon-sound reflex materialsh, gHigh soundproof capabilityh, and g low priceh 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 gwood workh or g concrete constructionh.

< Object >Precision instruments, auto-parts, electronic products, nanotechnology-related products,and environmental-related products.
