摘要 目的了解感音神经性聋患者平均听阈、不适阈和听觉动态范围。方法将2460例(4720耳)感音神经性聋患者分为男女两大组,每组分别按<30岁、30~60岁、>60岁分为三小组,分别进行纯音气导听阈、不适阈、听觉动态范围测试分析,测试结果以方差分析和LSD方法进行统计学处理。结果全部患耳0.5~4kHz平均听阈为73.00±21.07dB HL,平均不适阈为115.50±8.15dB HL,平均听觉动态范围为45.30±20.50dB。对男女性各组听阈、不适阈和听觉动态范围进行方差分析并用LSD方法进行两两比较差异无统计学意义(P>0.05)。男性在500、1000Hz的不适阈各组之间差异有显著统计学意义(P<0.05),女性左耳250、500Hz各组不适阈之间差异有显著统计学意义(P<0.05)。相关分析显示各频率听阈与不适阈、年龄与听阈、年龄与不适阈,年龄与听觉动态范围之间无相关性。结论听力门诊就诊的听障人士多为重度听力损失。不适阈一般不会超过116dB HL。听觉动态范围明显缩小。
