Noise, Vibration and Harshness is the study and manipulation of noise and vibration characteristic of vehicles. Müller HRM Engineering AB is involved in both interior and exterior NVH. In a complex system, such as a vehicle, there are various sources of noise and vibration as well as several transfer and radiation paths. Engine, driveline, tire contact patch, brakes and wind are a few examples of automotive NVH sources.
We have the expertise and the advanced tools for root cause analysis and NVH quality improvements using the principal means; source strenght reduction, isolation and absorption.
Modal Analysis, Transfer Path Analysis, Acoustic Intensity, Partial Coherence and Complete Vehicle Measurement are amongst our common investigative techniques.
