For the purpose of investigating to clarify the differential diagnosis and treatment of TMJ dysfunction, The TMJ sounds were analysed acoustically using accelerometers. The 101 TMJ sounds were recorded from 20 patients. Jaw movement and electromyogram (EMG) were recorded simultaneously. Comparison of the TMJ sounds to the jaw movement and EMG were made. The following conclusions were obtained: (1) TMJ sounds were classified into three clusters according to the total energy and band width. (2) It is possible to divide the changing of jaw moving velocity into three patterns. (3) It was found that the signal characteristics have relevance to the changing patterns of jaw moving velocity. (4) The acoustical study of TMJ sounds bring on the variable informations to clinical dentistry.
为了研究明确颞下颌关节紊乱病的鉴别诊断和治疗方法，使用加速度计对颞下颌关节声音进行了声学分析。从20名患者中记录了101次颞下颌关节声音。同时记录了下颌运动和肌电图（EMG）。对颞下颌关节声音与下颌运动及肌电图进行了比较。得出以下结论：（1）根据总能量和带宽，颞下颌关节声音可分为三类。（2）下颌运动速度的变化可分为三种模式。（3）发现信号特征与下颌运动速度的变化模式相关。（4）颞下颌关节声音的声学研究为临床牙科带来了多样的信息。
