use reverberation chamber and anechoic chamber to test the sound absorption performance of the part

R-cabinereverberation chamber  anechoic chamber

use impedance tube, reverberation chamber,anechoic chamber, airflow resistance and other equipments to test the acoustic performance of the materials

impedance tube

airflow resistance

anechoic chamber


reverberation chamber

use CAE modeling to estimate, develop and product the different levels of acoustic performance for auto parts. It can improve the efficiency and reduce the cost at the same time。
