VSAC(Vehicle Semi-Anechoic Chamber)


VSAC (Vehicle Semi-Anechoic Chamber) refers to a semi-anechoic chamber designed for vehicles.

Within the semi-anechoic chamber for vehicles, acoustical measurements and analyses are conducted on various components such as the automobile body, transmission system, and car air conditioning.

International standards tailored to measurement methods, including indoor pass-by, indoor coast-by, and proximity alert sound measurements, have been established.

In recent years, there has been a demand for high levels of sound insulation and absorption, as well as fire resistance, in conjunction with the prefabrication of anechoic chambers.

Both inside and outside the semi-anechoic chamber, there are various ancillary facilities depending on the object being measured, such as chassis dynamometers, wind tunnel testing facilities, local exhaust units, transportation equipment, and silencers for shafts.

Therefore, an anechoic chamber manufacturer needs comprehensive proposal capabilities, not only for the anechoic chamber itself.

Sonora Technology is capable of proposing semi-anechoic chambers, ancillary facilities, and acoustical measurement systems, among other offerings.
