Personal listening device (PLD) use with headphones is increasing in young adults and in most listening environments occur in background noise. Headphone choice can be important because certain headphones are more effective in limiting background noise than stock earbuds. Binge drinking, marijuana, and hard drug use have also been associated with high-volume PLD use. The purpose of this study was to explore the relationship between preferred headphone type, listening level, and other health risk behaviors.
Two-hundred and twenty undergraduates were recruited and completed a PLD use and risk behavior survey. Survey data included self-reported alcohol and marijuana use. Bilateral otoscopy, tympanometry, and pure-tone threshold testing (0.25-8 kHz) were completed. Participants listened to one hour of music using preferred headphone type with a probe microphone in the ear canal to measure equivalent continuous sound level (LAeq).
Mean LAeq was similar for the three types of headphones used. Participants who reported higher amounts of drinks per month and smoking marijuana within the last month had significantly higher LAeq levels than those who reported lower amounts of drinks per month and not smoking marijuana in the last month. There was no significant interaction between headphone type and reported drinks per month or marijuana use.
Young adults with normal hearing who have higher preferred listening levels also reported more alcohol and marijuana use, although headphone type was not associated with any of these variables.
在年轻人中，使用头戴式个人收听设备（PLD）的情况日益增多，并且在大多数收听环境中都存在背景噪音。耳机的选择可能很重要，因为某些耳机在限制背景噪音方面比原装耳塞更有效。狂饮、吸食大麻和使用硬性毒品也与高音量使用PLD有关。本研究的目的是探讨首选耳机类型、收听音量与其他健康风险行为之间的关系。
招募了220名本科生，他们完成了一项关于PLD使用和风险行为的调查。调查数据包括自我报告的酒精和大麻使用情况。完成了双侧耳镜检查、鼓室导抗图检查和纯音阈值测试（0.25 - 8kHz）。参与者使用首选的耳机类型听一小时音乐，同时在耳道内放置一个探头麦克风以测量等效连续声级（LAeq）。
所使用的三种类型耳机的平均LAeq相似。报告每月饮酒量较高且在过去一个月内吸食大麻的参与者的LAeq水平显著高于报告每月饮酒量较低且在过去一个月内未吸食大麻的参与者。耳机类型与报告的每月饮酒量或大麻使用之间没有显著的交互作用。
听力正常的年轻人中，偏好收听音量较高的人也报告了更多的酒精和大麻使用情况，尽管耳机类型与这些变量中的任何一个均无关联。
