The aim of this research was to investigate the acoustic characteristics of clicking sound.<BR>In this article, Peak Sound Pressure Level (PSPL) and Mean Power Frequency (MPF) were studied, and the relation of both parameters was investigated. The subjects were 6 patients with unilateral reciprocal clicking caused by anterior displacement of the disc with reduction. The results were as follows.<BR>1. The mean values of PSPL ranged 78.2dB-103.2dB.<BR>2. The mean values of MPF ranged 428Hz-758Hz.<BR>3. According as PSPL increased, MPF shifted higher range in 4 of the 6 subjects.
