背景:研究表明扩展高频测听可以反映耳蜗的早期病变,对监测耳毒性听力损失,老年性听力减退,噪声性听力减退等有重要价值。目的:了解无工业噪声污染地区居民的扩展高频听力状况、探讨扩展高频测听对早期发现噪声性聋的敏感性,为噪声性聋的早期防治提供参考依据。设计:以正常人群为研究对象,横断面调查,观察对比研究。单位:由南京大学医学院附属鼓楼医院耳鼻咽喉科、解放军第四军医大学附属西京医院耳鼻咽喉科与德国吉森大学医学院听觉研究中心合作进行。对象:2001-05/2002-01在青海省高原地区的无工业噪音污染区选择受试者共计300例,进行高频测听为主的听力检测。男174例,女126例。按年龄分为6～12岁的儿童组和13～30岁的青少年组,同时在南京市选择年龄、性别相匹配的健康人300例作为对照组。方法:两组经过筛选程序入选后均进行高频测听为主的全套听力检测及个人史的问卷调查。将两组的0.25～16kHz的各相对频率听阈值进行样本均数的显著性t检验,观察两组扩展高频听阈的差异性。主要观察指标:两组0.25～16kHz听阈的差异性。结果:低频及语言频率上的听阈两组之间差异无显著性意义,随着频率的递增,高频阈值升高,测得听阈的可能性减小。但在6kHz以上的扩展高频上,实验组听阈在个别频率上显著高于对照组。(P<0
Background: Studies have shown that the expansion of high frequency audiometry can reflect the early lesions of the cochlea, and is of great value in monitoring ear hearing loss, senile hearing loss and noise hearing loss. OBJECTIVE: To understand the extended HF audiometry of residents without industrial noise pollution and to explore the sensitivity of HF audiometry to the early detection of noise-induced deafness and to provide a reference for the early prevention and treatment of noise-induced deafness. Design: The normal population as the research object, cross-sectional survey to observe the comparative study. Unit: Department of Otolaryngology, Drum Tower Hospital Affiliated to Nanjing University Medical College, Xijing Hospital Affiliated to the Fourth Military Medical University of PLA, Department of Otorhinolaryngology, and Gensan University Medical Center Institute of Auditory Research in cooperation. PARTICIPANTS: A total of 300 subjects were selected in the non-industrial noise-polluted area of Qinghai Plateau in 2001-05 / 2002-01 for hearing test based on high-frequency audiometry. There were 174 males and 126 females. According to the age group of 6 to 12 years old children and 13 to 30 years old group of adolescents, while in Nanjing, 300 healthy people of the same age and gender were selected as the control group. Methods: Two sets of high frequency audiometry were selected after the selection of a full set of hearing tests and personal history of the questionnaire survey. The two groups of 0.25 ~ 16kHz relative frequency threshold for the sample mean t test, to observe the difference between the two groups to expand high-frequency hearing threshold. MAIN OUTCOME MEASURES: The difference of hearing threshold between 0.25 ~ 16 kHz in two groups. Results: There was no significant difference between the two groups in hearing threshold at low frequency and speech frequency. As the frequency increased, the threshold of high frequency increased and the probability of hearing threshold decreased. However, in the extended high frequency above 6kHz, the experimental group hearing threshold was significantly higher than the control group on individual frequencies. (P <0
