Noise source separation in diesel engines: application to acoustic listening tests

Résumé

This article discusses the extraction of combustion noise from diesel engines using a Wiener filter. Using the ESPRIT method, the filter is set to a limited number of modes, in order to reduce the amount of information it contains. It is estimated for various engine settings (load and engine speed). For this reason, real filters and their estimations are used to synthesise the noises. A perceptive experiment is conducted on these sounds in order to ensure that certain parameter filters enable the extraction of sounds similar to the combustion noises obtained by the measured filters. The aim of this work is therefore to evaluate the influence of the filter estimation conditions on the perception of the combustion noises that they help to synthesise.
