Automotive Research Testing Center

Description

Automotive Noise Testing Laboratory is dedicated for noise regulation test and NVH quality improvement. We have broad capabilities in noise/vibration measurements, provide technical service either in accordance with international test standards, or by customized procedures. For NVH quality improvement, we have plentily experiences in root-cause and modification study. Besides, we can develop customised instruments to help customers setup their own R&D capabilities and get over with product optimazion.
