听力障碍在自闭症谱系障碍（ASD）患者中比一般人群更为普遍，尽管ASD不是由听力障碍引起的，但听力困难可能会使症状恶化。60名ASD参与者和16名5-18岁的正常发育同伴接受了交流能力（表达性和接受性语言、言语清晰度、语音处理和声音情感识别）和听力学（纯音听力学、不舒服的响度水平、鼓室测量、声反射、失真产物耳声发射和听觉脑干反应）的全面筛查。ASD组在至少一项听力学功能测量中发现异常的比率（55%）高于正常发育的同龄人（14.9%）或一般人群的估计（6%）。与正常发育的参与者（0%）或一般人群的估计（8-15%）相比，ASD组至少一只耳朵的声音敏感性（37%）也要高得多。当ASD参与者被分为有和没有听力异常证据的组时，在沟通方面没有显著的组差异；然而，当听力阈值与沟通之间的关系被检查时，中频阈值（2000Hz）实际上与所有言语清晰度和语言测量的表现显著相关。这些结果表明，将听力分为正常与异常可能不足以了解其与ASD症状的关系，并且对轻度/亚临床听力损失的治疗研究可能对ASD儿童有价值。
Hearing impairment is more prevalent in individuals with Autism Spectrum Disorders (ASD) than the general population, and although ASD is not caused by hearing impairment, symptoms may be made worse by difficulty hearing. Sixty participants with ASD and 16 typically developing peers ages 5-18 underwent a comprehensive screening of communication abilities (expressive and receptive language, speech articulation, phonological processing, and vocal emotion recognition) and audiology (pure tone audiometry, uncomfortable loudness level, tympanometry, acoustic reflexes, distortion product otoacoustic emissions, and auditory brainstem response). The ASD group had a higher rate (55%) of abnormal findings on at least one measure of audiological functioning than typically developing peers (14.9%) or the general population estimate (6%). The presence of sound sensitivity in at least one ear was also considerably higher for the ASD group (37%) compared to the typically developing participants (0%) or general population estimates (8-15%). When participants with ASD were divided into groups with and without evidence of abnormal audiology, there were no significant group differences in communication; however, when the relationship between hearing thresholds and communication was examined, thresholds at middle range frequencies (2000Hz) were in fact significantly related to performance on all measures of speech articulation and language. These results suggest that classifying hearing as normal versus abnormal may not be sufficient to understand its association with ASD symptoms and that treatment studies for mild/subclinical hearing loss may be worthwhile for children with ASD.
