摘要

Noise-Induced Hearing Loss (NIHL) is a growing concern among young adults, particularly medical students who frequently use personal listening devices (PLDs). Despite awareness of the risks, unsafe listening practices remain common and can have long-term consequences. This study aimed to assess the awareness, knowledge, and listening practices of medical students regarding NIHL and the use of PLDs such as headphones and earphones. A cross-sectional, questionnaire-based survey was conducted with 139 medical students. Students completed a structured questionnaire assessing their device usage habits, symptoms of hearing difficulty, awareness levels, and attitudes towards preventive measures. Data were analyzed to identify patterns and gaps in knowledge and behaviour. Among the 139 students, 68.3% preferred earphones, and 56.8% reported constant use of PLDs. Although 78.4% of students recognised the harmful effects of high-volume listening, unsafe practices remained prevalent. Approximately 60% of the students listened at volume levels between 50% and 79%, and nearly half listened for more than 2 h per day. Symptoms such as tinnitus (36% reported “sometimes” or “usually”), frequent repetition in conversations (57.6%), and the need to increase the TV or radio volume (56.1%) were frequently observed. Despite 77.7% of the students believing that NIHL is preventable, 25.2% admitted to lacking sufficient knowledge, and approximately 30% were unaware of harmful noise thresholds. Awareness of NIHL exists among medical students, but it does not consistently lead to protective listening behaviours. Educational programs and preventive strategies should be emphasised early to safeguard hearing health and promote safer device usage habits.
