本文对听力正常的主观性耳鸣患者进行单耳双音低频敏化反应的测试,以了解耳鸣患者的声反射(AR)敏化情况.1 资料与方法1.1 资料 耳鸣组30例(52耳)中,男性11例,女性19例;单侧耳鸣8例,双侧耳鸣22例;年龄15～52岁,平均年龄28.1±12.2岁;病程5月～12年不等.纯音听阈0.5～8kHz倍频程均值<25 dB HL,鼓室压图均为A型,声反射衰减阴性,临床上排除传导性聋及蜗后病变.随机抽选健康青年人20例(40耳),男女各半为对照组.
In this paper, the hearing of subjective tinnitus patients with monaural two-tone low frequency sensitization test to understand the tinnitus patients with acoustic reflex (AR) sensitization.1 Materials and Methods 1.1 Information tinnitus group of 30 patients (52 ears) , 11 males and 19 females; unilateral tinnitus in 8 cases, bilateral tinnitus in 22 cases; aged 15 to 52 years, mean age 28.1 ± 12.2 years; duration of 5 months to 12 years. Pure tone audiology 0.5 ~ 8kHz octave The mean value was <25 dB HL, tympanogram was type A, negative acoustic reflex attenuation, clinical deafness and cochlear lesions were excluded.Of healthy young people were randomly selected in 20 cases (40 ears), male and female half of the control group .
