Abstract

Objective: To investigate the effects of personal listening device use on hearing in young listeners.

Methods: Conventional frequency audiometry (0.5-8 kHz) and extended high-frequency audiometry (10-20 kHz) were performed on 120 personal listening device users and 30 normal-hearing young adults.

Results: The hearing thresholds in the 3 to 8 kHz frequency range were significantly increased in the personal listening device listeners. The frequency range of the increased thresholds became broad as the exposure duration was increased. Impaired hearing was detected in 14.1% (34 of 240 ears) of ears (> 25 dB HL in one or more frequencies in 0.5-8 kHz). The hearing thresholds of extended high-frequency audiometry in personal listening device users could also be increased even if their hearing thresholds in conventional frequency audiometry were normal.

Conclusion: Our results suggest that long-term use of personal listening devices can impair hearing function The data also indicate that extended high-frequency audiometry is a sensitive method for early detection of noise-induced hearing loss.

青少年个人听力设备对听力损害的风险。

目的:探讨个人助听器使用对青少年听者听力的影响。方法:采用常规频率测听(0.5 ~ 8khz)和扩展高频测听(10 ~ 20khz)对120名个人助听器使用者和30名听力正常的青年进行测听。结果:听力听者在3 ~ 8 kHz频率范围内的听力阈值明显升高。随着暴露时间的增加，阈值增加的频率范围变宽。在0.5-8 kHz范围内一个或多个频率> 25 dB HL的耳朵中，有14.1%(34 / 240耳)检测到听力受损。个人听力设备使用者在常规频率听力阈值正常的情况下，扩展高频听力阈值也可能升高。结论:长期使用个人助听设备会损害听力功能，扩展高频测听是早期发现噪声性听力损失的灵敏方法。
