The widespread use of mobile phones and personal listening devices (PLDs) poses potential health risks, particularly noise-induced hearing loss. Among younger generations, high-volume PLD use is associated with auditory and vestibular system changes. Clinical vestibular testing, including vestibular-evoked myogenic potentials (VEMP) and the video head impulse test (vHIT), may reveal peripheral vestibular impacts from prolonged PLD exposure at volumes over 60%. This study examines VEMP and vHIT results in individuals with normal hearing who have had extended high-volume PLD exposure. Subjects and.
A cross-sectional comparative study was conducted on individuals aged 15-24 years. All the participants had normal pure tone thresholds with "A" type tympanogram, present acoustic reflexes, and history of PLD usage. Participants were divided into groups according to PLD exposure of <1 year (group A), 1.1-2 years (group B), 2.1-3 years (group C), and 3.1-4 years (group D). The output sound pressure level (dB SPL) near the tympanic membrane was measured. Furthermore, cervical VEMP, ocular VEMP, and vHIT were assessed.
The VEMP and vHIT findings were statistically analyzed and compared across groups. The peak-to-peak amplitudes of VEMP showed a statistically significant difference between groups A and D.
Potential subclinical damage to the otolith organs can be associated with increased PLD exposure. No damage to the semi-circular canals was observed as the participants used lower dBA values by the PLDs.
手机和个人收听设备（PLD）的广泛使用带来了潜在的健康风险，尤其是噪声性听力损失。在年轻一代中，高音量使用PLD与听觉和前庭系统变化有关。临床前庭测试，包括前庭诱发肌源性电位（VEMP）和视频头脉冲试验（vHIT），可能揭示长时间以超过60%的音量使用PLD对周围前庭的影响。本研究调查了听力正常但长时间高音量使用PLD的个体的VEMP和vHIT结果。研究对象与方法：对15至24岁的个体进行了一项横断面比较研究。所有参与者纯音阈值正常，鼓室图为“A”型，声反射存在，且有PLD使用史。参与者根据PLD使用时间分为<1年组（A组）、1.1至2年组（B组）、2.1至3年组（C组）和3.1至4年组（D组）。测量鼓膜附近的输出声压级（dB SPL）。此外，评估了颈肌VEMP、眼肌VEMP和vHIT。结果：对VEMP和vHIT结果进行了统计分析并在各组间进行了比较。VEMP的峰峰值在A组和D组之间存在统计学显著差异。结论：耳石器官的潜在亚临床损伤可能与PLD使用时间增加有关。由于参与者使用PLD时的dBA值较低，未观察到半规管受损。
