Investigate hearing function and headphone listening habits in nine-year-old Swedish children.
A cross-sectional study was conducted and included otoscopy, tympanometry, pure-tone audiometry, and spontaneous otoacoustic emissions (SOAE). A questionnaire was used to evaluate headphone listening habits, tinnitus, and hyperacusis.
A total of 415 children aged nine years.
The prevalence of a hearing threshold ≥20 dB HL at one or several frequencies was 53%, and the hearing thresholds at 6 and 8 kHz were higher than those at the low and mid frequencies. SOAEs were observed in 35% of the children, and the prevalence of tinnitus was 5.3%. No significant relationship between SOAE and tinnitus was found. Pure-tone audiometry showed poorer hearing thresholds in children with tinnitus and in children who regularly listened with headphones.
The present study of hearing, listening habits, and tinnitus in nine-year old children is, to our knowledge, the largest study so far. The main findings were that hearing thresholds in the right ear were poorer in children who used headphones than in children not using them, which could be interpreted as headphone listening may have negative consequences to children's hearing. Children with tinnitus showed poorer hearing thresholds compared to children without tinnitus.
调查瑞典9岁儿童的听力功能及耳机使用习惯。
开展一项横断面研究,包括耳镜检查、鼓室声导抗测量、纯音听力测定和自发性耳声发射(SOAE)。使用一份问卷来评估耳机使用习惯、耳鸣和听觉过敏情况。
共415名9岁儿童。
在一个或多个频率上听力阈值≥20 dB HL的患病率为53%,6 kHz和8 kHz处的听力阈值高于低频和中频处的阈值。35%的儿童观察到有自发性耳声发射,耳鸣患病率为5.3%。未发现自发性耳声发射与耳鸣之间存在显著关系。纯音听力测定显示,有耳鸣的儿童以及经常使用耳机聆听的儿童听力阈值较差。
据我们所知,目前这项针对9岁儿童听力、聆听习惯和耳鸣的研究是迄今为止规模最大的。主要研究结果是,使用耳机的儿童右耳听力阈值比不使用耳机的儿童差,这可以解释为使用耳机聆听可能会对儿童听力产生负面影响。与无耳鸣的儿童相比,有耳鸣的儿童听力阈值较差。
