The noise and vibration generated by vehicles can be categorized into BSR(buzz, squeak, rattle) and NVH(noise, vibration, harshness). In real-world maintenance environments, approximately 70 % of issues are related to BSR, while the remaining 30 % are NVH problems. To address this, Hyundai Motor Company and SM Instruments jointly developed diagnostic equipment called the ‘Noise Observer.’ For BSR issues, it calculates time delays by zooming in on waveforms and provides objective analysis through trigger functions such as simple and picking. For NVH problems, it measures vibrations and noises in scenarios corresponding to customer complaints, then compares frequency analysis results and RPM measurements to assess rotor order. ‘Noise Observer’ has been adopted as standard equipment at Hyundai Motor Company’s High-tech Center to resolve customer complaints related to NVH and BSR issues. This tool enables mechanics, even those with limited NVH knowledge, to easily identify faulty components through measurement and analysis data. This paper explains the composition and software algorithms of the ‘Noise Observer’ and presents actual case studies where this diagnostic equipment successfully resolved customer complaints.
