Anechoic chamber designs the sound insulation layer and sound absorption layer according to the environment required for measurement (indoor sound absorption characteristics, indoor background noise).

Sonora’s Anechoic chamber is a modular type, so it is established by shipping the unit manufactured in Japan overseas and assembling the parts locally.

There are two types of anechoic chambers: fully anechoic chambers and semi-anechoic chambers. For simple measurements, you can also use an anechoic box.
