Profile: Eckel Industries of Europe Ltd. designs and manufactures noise control products. We supply, design and install hemi (semi) and anechoic chambers. Our chambers can be fitted with metallic, fiberglass, foam, and e-element, or compact anechoic wedges/absorbers. Another area we support is double acting and shock absorbing traffic doors. Anechoic chambers are echo-free enclosures with a sound energy absorption level of 99% to 100%, or a reflected sound pressure level of 10% or less. The frequency at which the energy absorption drops below 99%, or the pressure reflection exceeds 10%, is known as the low-frequency cut-off. Sound absorption is obtained by lining the walls, ceilings, and floor with wedges or other sound absorbing elements or supersoft panels, depending on performance level required and cut-off desired.
