To assess the prevalence of hyperacusis and severe hyperacusis among children and adolescents seen at an audiology outpatient tinnitus and hyperacusis service.
This was a retrospective study. Hyperacusis was considered as present if the average uncomfortable loudness level (ULL) at 0.25, 0.5, 1, 2, 4 and 8 kHz for the ear with the lower average ULL, which is denoted as ULLmin, was ≤77 dB HL. Severe hyperacusis was considered as present if the ULL was 30 dB HL or less for at least one of the measured frequencies for at least one ear.
There were 62 young patients with an average age of 12 years (SD = 4.1 years, range 4-18 years).
Eighty-five percent of patients had hyperacusis and 17% had severe hyperacusis. On average, ULLs at 8 kHz were 9.3 dB lower than ULLs at 0.25 kHz. For 33% of patients, ULLs were at least 20 dB lower at 8 than at 0.25 kHz.
Among children and adolescents seen at an audiology outpatient clinic for tinnitus and hyperacusis, hyperacusis diagnosed on the basis of ULLs is very prevalent and it is often characterised by lower ULLs at 8 than at 0.25 kHz.
评估在听力门诊耳鸣与听觉过敏服务中心就诊的儿童及青少年中听觉过敏和重度听觉过敏的患病率。
这是一项回顾性研究。如果双耳中平均不舒适响度水平（ULL）较低的那只耳朵（记为ULLmin）在0.25、0.5、1、2、4和8千赫时的平均不舒适响度水平≤77分贝听力级，则认为存在听觉过敏。如果至少一只耳朵在至少一个测量频率下的ULL为30分贝听力级或更低，则认为存在重度听觉过敏。
有62名年轻患者，平均年龄12岁（标准差=4.1岁，范围4至18岁）。
85%的患者有听觉过敏，17%的患者有重度听觉过敏。平均而言，8千赫时的ULL比0.25千赫时的ULL低9.3分贝。对于33%的患者，8千赫时的ULL比0.25千赫时至少低20分贝。
在听力门诊耳鸣与听觉过敏诊所就诊的儿童及青少年中，基于ULL诊断的听觉过敏非常普遍，其特征通常是8千赫时的ULL低于0.25千赫时的ULL。
