Abstract

This paper reports the development of a multiple microphone system for measuring acoustic cavity resonance of a tire model. Distribution of sound pressure level is measured in the tire model by the multiple microphone system. This system is composed of 32 condenser microphones mounted concentrically on the upper side of the model. The first and second modes of acoustic resonance were observed by the system.
