Online Masterclass on EV / HEV NVH Engineering - EV Road Noise & Wind Noise
Critically important to you may need to find the noise root cause and act on it. Depending on the origin of the noise source, different NVH analysis techniques are required.
Importantly, you may need to find the noise root cause and act on it. Depending on the origin of the noise source, different NVH analysis techniques are required. Reducing wind noise, for instance, happens most effectively in wind tunnels.
These allow to effectively isolate the wind noise from other noise sources and find the most effective measures to reduce this annoying source.
However, as these tests are extremely costly, it is crucial to test with extremely efficient measurement techniques. The use of industrialized testing processes based on large beamforming arrays that allow identification of the exterior noise sources and use this data to decide what to test next becomes more and more a reference.
