早在上世纪70年代,当静态鼓室图已作为检测中耳功能的常规手段时,已有学者发现,用200~2000Hz频率的探测音分别记录鼓室图时,随着探测音的不同,分别记录到不同的鼓室图。鼓室图的变化主要与频率有关。Colletti(1976)报道用这种方法检测中耳的传导系统鼓膜听骨链的微小病变比常规 As early as the 70s of last century, when the static tympanogram has been used as a conventional measure of middle ear function, some scholars have found that when the tympanometric images are recorded respectively with the probe sound at a frequency of 200-2000 Hz, as the probe sound is different, Into a different tympanum map. Tympanogram changes mainly related to frequency. Colletti (1976) reported that using this method to detect small lesions of the ossicular chain of the tympanic membrane of the middle ear,
