CLUSTERING INVERSE BEAMFORMING FOR VEHICLES NVH
24th International Conference on Sound and Vibration 2017, London CallingClustering Inverse Beamforming is an array-based acoustic imaging technique to solve inverse problems formulated by discretizing the source region into elementary equivalent sources. It is based on a statistical processing of multiple realizations of the acoustic image, related to the investigated source region, iteratively obtained solving the ...

Automotive megatrends and their impact on NVH
2019The ongoing transformation of individual mobility will decisively change future vehicles. The acronym CASE, created by Daimler in 2016, sums up four megatrends in one abbreviation: Connected, Autonomous, Shared and Electric. This paper is meant to discuss the resulting consequences regarding NVH.

SAE Technical Paper Series, 1999
<div class="htmlview paragraph">The problem of NVH CAE model correlation in light of test and product variation has been addressed. An objective metric based on statistical hypothesis testing has been proposed and evaluated. This technique has been shown to work for frequency response functions.
