Applications for Your Test Chambers
Noise Reduction and sound design for vehicles and household appliances require appropriate testing conditions. FAIST provides testing facilities, such as engine and power train test cells, as well as vehicle test cells for interior and exterior noise measurements. The test cells are equipped with our innovative broadband compact absorbers (BCA) conforming to ISO 3745.

In order to provide a serious alternative to conventional absorbers with a minimum size of a quarter wavelength of the cutoff frequency, FAIST and the Fraunhofer Institute for Building Physics (IBP) have developed a space-saving special broadband resonant absorber. This absorber achieves high absorption efficiency down to 30 Hz with a lining thickness of only 250 mm and an even surface. The BCA allows class 1 free field rooms for measurements according to ISO 3745.
