NVH Institute Introduction      

        NVH Institute belongs to Wuxi Gissing Auto Acoustic Parts Tech. CO.,Ltd. It has an anechoic chamber with 4-wheel drive vehicle NVH dynamometer, two anechoic chambers, two reverberation chambers and a sound quality jury room. It has the ability to research and develop material, component and the whole vehicle .

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

R-cabine

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。
