通过访谈、听诊和电子记录，记录了 98 名正畸固位患者的颞下颌关节 (TMJ) 声音，平均年龄 19 +/- 8.6 (s.d.) 岁。 41% 的受试者通过听诊发现声音，32% 的受试者通过访谈发现声音，女性多于男性（P < 0.05）。使用一种新的时频分析方法，即减少干扰分布 (RID)，根据能量峰值的位置和数量，将电子录音分为五个子类，即 RID 类型 1-5。 RID 类型 1-3 有几个时间接近的能量峰值。 RID 类型 4-5 是典型的捻发音受试者，在 20-300 毫秒的时间内出现多个能量峰值。 RID 1 型存在于 45% 的受试者中，是典型的咔嗒声患者，其主要能量峰值位于 < 600 Hz 的频率范围内，并且在女性受试者中明显比男性受试者更常见 (P < 0.01)。 68% 的受试者中发现 RID 2 型，主峰在 600-1200 Hz 范围内；RID 3 型在 38% 的受试者中发现，峰值在 > 1200 Hz 频率范围内，发现具有相似的性别分布。 49% 的受试者存在 RID 类型 4，其能量峰值分布在 < 600 Hz 的频率范围内。 RID 5 型存在于 43% 的受试者中，女性比男性更常见 (P < 0.05)，其峰值分布在从约 30 Hz 到约 3000 Hz 的整个频率范围内。总之，通过显示 RID 比听诊可以对 TMJ 声音进行更详细的分类。这表明 RID 分类方法可能提供一种区分指示不同类型病理的声音的方法。
Temporomandibular joint (TMJ) sounds were recorded in 98 orthodontic retention patients, mean age 19 +/- 8.6 (s.d.) years, by interview, auscultation and electronic recording. Sounds were found by auscultation in 41% and by interview in 32% of the subjects, more often in females than in males (P < 0.05). A new method for time-frequency analysis, the reduced interference distribution (RID), was used to classify the electronic sound recordings into five subclasses, RID types 1-5, based upon location and number of their energy peaks. RID types 1-3 had a few energy peaks close in time. RID types 4-5, typical of subjects with crepitation, had multiple energy peaks occurring close in time for a period of 20-300 ms. RID type 1, found in 45% of the subjects, typical of patients with clicking, had its dominant energy peak located in a frequency range < 600 Hz and was significantly more common in the female than in the male subjects (P < 0.01). RID type 2, found in 68% of the subjects, with the dominant peak in the range 600-1200 Hz, and RID type 3, found in 38% of the subjects, with the peak in the frequency range > 1200 Hz, were found to have a similar gender distribution. RID type 4, found in 49% of the subjects, had the energy peaks distributed in the frequency range < 600 Hz. RID type 5, found in 43% of the subjects, more often in females than in males (P < 0.05), had the peaks distributed over the whole frequency range from about 30 Hz up to about 3000 Hz. In conclusion, a more detailed classification could be made of the TMJ sounds by displaying the RIDs than by auscultation. This suggests that RID classification methods may provide a means for differentiating sounds indicating different types of pathology.
