Highlights
The analysis of acoustic phenomena inside the car with an indication of their significance and location is a complex task
A typical measurement technique for the vibroacoustics of the car interior is the measurement of sound pressure using a microphone
In the acoustics of the car interior, which are very complex [6,8,12,13,14,15,17], the information provided by the sound pressure is often insufficient
Summary
The analysis of acoustic phenomena inside the car with an indication of their significance and location is a complex task. The method enabling the verification of the theses will be based on the implementation of software for processing the collected data from one or more intensity probes and specific processing of the collected signals It will be bandpass filtering of the signal, with particular emphasis on filters with zero phase distortion. In the tests of the run-up and run-down of the passenger car radiator fan, which was a pilot of the discussed subject, the p-u type 3D intensity probes (Fig. 2), with 3 orthogonal particle acoustic velocity sensors and a microphone, were used to collect relevant data. Aerodynamic noise, ventilation outlets or exhaust streams will not be the subject of the team's work
