Tire cavity noise is one of the main road noise issues that contribute significantly to noise at vehicle interior. It is very difficult to improve tyre cavity noise as cavity pressure acts as an exciting force and its low damping and high gain characteristics dominate the vibrations of both suspension and body. Precise measurement of this noise in real systems becomes more important besides theoretical calculations to understand the source and critical transmission paths that reaches the receiver.In this study, a Tyre Cavity Microphone (TCM) fitted inside the tyre on wheel rim is used to identify the tyre cavity resonant mode frequencies distinguished from close proximity noise frequencies.
