|Title:||Vehicle Pass-by Noise Source Localization Using Generalized Inverse Beamforming|
|Abstract:||Pass-by noise level is an important design criterion for vehicle engineering development, and tools for better understanding the subsystems contributions on the recorded levels during passages are of most interest. One of the recent techniques applied for this purpose is beamforming, which uses an array of microphones to generate mappings of sound radiation sources. In this work, the generalized inverse beamforming is used to investigate the advantages on this approach in a passenger vehicle pass-by noise assessment. A simplified moving source modeling is adopted. The localization performance is investigated using a known source and the influence of block size and averaging is also discussed. In the end, vehicle noise analysis is presented with order and spectrum peak mappings. Copyright © (2011) by the International Institute of Acoustics & Vibration.|
