Identification of vehicle interior noise sources using vibro-acoustic spectral analysis method

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Continuous exposure to sound emitted by road vehicles will have direct effect on the comfort and fitness of the drivers, especially during long distance travel. It is imperative that automotive manufacturers invest a lot of effort and money to improve and enhance the vibro-acoustics performance of their product. The enhancement effort would be very difficult and time consuming if one relies only on 'trial and error' methods without prior knowledge about the sources itself. Complex interior noise inside the vehicle cabin originated from various sources and travel through many pathways. It is vital for the automotive engineers to identify the dominant noise sources from measurement data obtained inside the vehicles such as tyre noise, engine noise, exhaust noise and noise due to turbulence. In this paper, a multi-channel analyzer is utilised to measure and record vibro-acoustic signals. Computational algorithms are also employed to identify contribution of the various sources towards the measured signals. These achievements can be utilised to detect, control and optimise interior noise performance of road transport vehicles.
