Comparison of Two Measurement Methods for Exterior Noise Radiation Characterization of a Loaded Rotating Tyre 2015-01-2197
In the context of the reduction of traffic-related noise the research reported in this paper provides tools that could be used to develop low noise tyres.
Two measurement techniques have been analyzed for exterior noise radiation characterization of a loaded rotating slick tyre on a rough road surface.
On one hand sound pressure measurements at low spatial resolution with strategically placed microphones on a half-hemisphere around the tyre/road contact point have been performed. This technique provides a robust solution to compute the (overall) sound power level.
On the other hand sound intensity measurements at high spatial resolution by means of a scanning intensity probe have been performed. This technique allows a more detailed spatial visualization of the noise radiation and helps in getting more insight and better understanding of the acoustical phenomena.
