Noise-induced hearing loss (NIHL) has been found in rural children, potentially due to occupational and recreational noise exposure without consistent use of hearing protection devices (HPDs). However, questions remain regarding the specifics of rural adolescents' noise exposure and use of hearing protection around different types of noise. As such, the purpose of the current study was to provide preliminary results on rural adolescents' noise exposure and use of hearing protection for gunfire, heavy machinery, power tools, all-terrain vehicles (ATVs), and music.
A questionnaire was administered to 197 students (seventh to 12th grade) from rural schools in West Texas. Questions were related to noise exposure and use of HPDs for specific categories of noise. Testing was performed at the schools, with an investigator recording each student's responses.
Approximately 18%-44% of adolescents reported exposure 12 or more times a year to gunfire, heavy machinery, power tools, and ATVs. Only 1%-18% of the adolescents reported never being exposed to such noise sources. Almost half of rural adolescents never used hearing protection around gunfire, and 77%-91% reported never wearing hearing protection when exposed to heavy machinery, power tools, and ATVs.
The current study revealed that rural adolescents are exposed to noise sources that could damage their hearing. However, the majority of rural adolescents do not consistently wear hearing protection. Additional research is now needed to extend these findings by assessing rural adolescents' duration of exposure to different noise sources, in addition to investigating prevention of NIHL in this population.

噪声性听力损失(NIHL)已在农村儿童中发现,这可能是由于职业和娱乐性噪声暴露而没有持续使用听力保护装置(HPD)所致。然而,关于农村青少年在不同类型噪声下的噪声暴露和听力保护使用的具体情况仍存在疑问。因此,本研究的目的是初步了解农村青少年在枪声、重型机械、电动工具、全地形车(ATV)和音乐方面的噪声暴露和听力保护使用情况。
对来自德克萨斯州西部农村学校的 197 名(七至十二年级)学生进行问卷调查。问题与特定噪声类别的噪声暴露和 HPD 使用有关。在学校进行测试,由一名调查员记录每个学生的回答。
约 18%-44%的青少年报告说,每年有 12 次或更多次暴露于枪声、重型机械、电动工具和 ATV 中。只有 1%-18%的青少年报告从未接触过此类噪声源。近一半的农村青少年在枪声周围从未使用过听力保护,而 77%-91%的青少年在接触重型机械、电动工具和 ATV 时报告从未佩戴过听力保护。
目前的研究表明,农村青少年暴露于可能损害听力的噪声源中。然而,大多数农村青少年并没有持续佩戴听力保护装置。现在需要进一步研究,通过评估农村青少年接触不同噪声源的时间长度,以及调查在该人群中预防 NIHL 的方法,来扩展这些发现。补充材料:https://doi.org/10.23641/asha.17139335。
