Anechoic box

An anechoic box is a small acoustic box for acoustic measurements. Unlike an anechoic chamber, it is not possible to make acoustic measurements in accordance with the ISO standards, however, correlative and comparative measurements are feasible by making corrections based on the master data acquired in the anechoic chamber.
In order to make acoustic measurements, acoustic analyzers such as sound level meter and FFT analyzer are used to inspect the acoustic characteristics and abnormal noises in small drive components, speakers, telecommunications equipment…etc.

Sonora Technology has developed anechoic boxes with extremely high sound insulating value, even higher than that of anechoic chambers. That allow to set a background noise in the box to a lower level. Depending on the installation environment, a single-digit background noise can be ensured. *OA3.5dB (actual value) 

No assembly work required

Unlike an anechoic chamber, it has the advantage that there is no need to assemble it on-site.
So all you have to do is carry in and install the anechoic box exported from Japan.

Extensive customizability

According to the measurement methods, Sonora Technology will suggest how to set up objects to be measured and microphones. Various customization can be applied including sliding table, clumps for microphone, cable ports, lighting and coupling.
