耳鸣是令人极为烦恼的一种症状,也是患者经常看听力门诊的主要原因。通常认为耳鸣和各种病因造成的听力损失有关系。本文研究试图确定高频(9～20KHz)听力测试和听性脑干反应(ABR)在耳鸣诊断中的意义,以及补充、扩大现有的对听力正常者耳鸣的性质和起因的认识。作者选用17名耳鸣患者为实验组,年龄21～45岁、平均35岁,听敏度均正常(在0.25～8KHz 各频率的阈值≤20dBHL)。无耳
Tinnitus is a very troubling symptom and is the main reason that patients often see hearing clinics. Tinnitus is generally thought to be linked to hearing loss caused by various causes. This study attempts to determine the significance of high frequency (9 ~ 20KHz) audiometry and auditory brainstem response (ABR) in the diagnosis of tinnitus and to complement and expand existing understanding of the nature and causes of tinnitus in normal hearing. The authors selected 17 tinnitus patients for the experimental group, aged 21 to 45 years, mean 35 years old, normal hearing sensitivity (0.25 ~ 8KHz frequency threshold ≤ 20dBHL). No ears
