IDENTIFICATION OF RATTLE NOISE SOURCES IN THE VEHICLE CABIN USING AN ACOUSTIC CAMERA

Driving comfort in the car cabin depends on the prevailing acoustic climate. The occurrence of various types of intermittent noises is a common phenomenon observed by users of motor vehicles. In the cabins of motor vehicles, a local source of non-stationary noise due to the propagation of sound waves in the air and in the structural structure makes it practically impossible to determine its location organoleptically. The article presents the use of an acoustic camera to locate noise sources. Research was presented in the field of recognizing the location of sources intentionally introduced into the cabin and identifying spontaneous sources caused by operational wear. The obtained results confirmed the usefulness of using an acoustic camera in identifying noise sources, however, the presence of apparent sources may in some cases result in incorrect diagnoses.
