近期,Nature子刊《Scientific Reports》期刊发表了一篇学术文章,揭示了当下青少年沉迷喧嚣音乐,易引发耳鸣等问题的现状。现在的年轻人喜欢戴耳机沉浸在高分贝音乐的世界里,研究人员对此表示担忧,因为这种习惯容易导致过早失聪。

当内耳的耳蜗毛细胞受损会引发耳鸣。长时间聆听噪音或者高分贝声音会使得这些细胞“不堪重负”,从而引发暂时性或者永久性损害。而且,这种伤害会迫使耳朵其他部件“加倍工作”,导致耳鸣并最终引发听力受损。

通常耳鸣的症状多出现于老年人群体,但是越来越多的青年人出现耳鸣困扰,这主要与他们常见用耳机听音乐有关联。耳鸣是听力丧失的典型症状。

来自于圣保罗大学医学院的研究团选取了170名年龄在11至17岁青少年作为调查对象,对他们的耳朵进行健康检查。对于患有耳鸣的学生,研究人员记录了他们耳鸣的时间、频率。

结果显示,超半数的青少年(54.7%)有过耳鸣的症状,大多数都曾定期听过吵闹的音乐。文章作者、耳鼻喉科副教授Tanit Ganz Sanchez表示,患病率让人吃惊。如果青少年持续暴露在高分贝环境下,他们可能会在40岁、甚至于30岁的时候就出现失聪。

Sanchez博士强调,如果青少年长时间沉迷于爆破性音乐,一直到20岁或者25岁,这种举措将可能永久性伤害耳蜗毛细胞突触。

更令人担忧的是,很多青少年并不关心这一问题,自然也不会告诉父母或者老师。这常常会延误他们就诊的最佳时机,导致听力问题加重。

  • Tinnitus is associated with reduced sound level tolerance in adolescents with normal audiograms and otoacoustic emissions

    Recent neuroscience research suggests that tinnitus may reflect synaptic loss in the cochlea that does not express in the audiogram but leads to neural changes in auditory pathways that reduce sound level tolerance (SLT). Adolescents (N = 170) completed a questionnaire addressing their prior experience with tinnitus, potentially risky listening habits, and sensitivity to ordinary sounds, followed by psychoacoustic measurements in a sound booth. Among all adolescents 54.7% reported by questionnaire that they had previously experienced tinnitus, while 28.8% heard tinnitus in the booth. Psychoacoustic properties of tinnitus measured in the sound booth corresponded with those of chronic adult tinnitus sufferers. Neither hearing thresholds (≤15 dB HL to 16 kHz) nor otoacoustic emissions discriminated between adolescents reporting or not reporting tinnitus in the sound booth, but loudness discomfort levels (a psychoacoustic measure of SLT) did so, averaging 11.3 dB lower in adolescents experiencing tinnitus in the acoustic chamber. Although risky listening habits were near universal, the teenagers experiencing tinnitus and reduced SLT tended to be more protective of their hearing. Tinnitus and reduced SLT could be early indications of a vulnerability to hidden synaptic injury that is prevalent among adolescents and expressed following exposure to high level environmental sounds.
