Automotive Noise Testing

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