Awareness of Noise-Induced Hearing Loss Related to Exposure to High-Noise Environments—Case Study: Young Adults 18 to 30 in Greece

<b>Background:</b> Noise-induced hearing loss (NIHL) is one of the most common types of hearing impairment, even though it is preventable. However, awareness and protective behaviors among young adults remain limited. This study explored the knowledge, attitudes, and behaviors of young adults in Greece regarding exposure to high-noise environments and the risk of NIHL. <b>Methods:</b> A cross-sectional survey was conducted with 104 participants aged 18-30 years in Patras, Greece. A 27-item questionnaire was used to collect data on demographics, patterns of noise exposure, use of personal listening devices, auditory symptoms, and preventive behaviors. Descriptive statistics and chi-square tests were used to examine relationships between demographic variables and participants' responses. <b>Results:</b> Most participants (93.3%) recognized that prolonged exposure to high noise levels can harm hearing. However, only 6.7% reported having regular hearing checks, and almost half (45.2%) had never been tested. Remarkably, 19.2% of participants experienced tinnitus, while more than half (54.8%) reported fatigue after exposure to loud sounds. Younger participants (aged 18-22 years) were significantly more likely to listen at high volumes compared to older groups (<i>p</i> < 0.05). Males reported higher rates of tinnitus and ear discomfort, whereas females more often experienced headaches. Although general awareness of NIHL was high, preventive behaviors such as using hearing protection were rarely practiced. <b>Conclusions:</b> These findings highlight the need for targeted educational campaigns and preventive screening programs to promote safe listening practices and reduce the overall prevalence of NIHL.
