ABSTRACT Introduction: Noise exposure is one of most common causes of hearing loss according to the World Health Organization (WHO). The use of personal music players is one of the sources of this harmful noise, which has been demonstrated to constitute a risky habit. Previous studies have found hearing loss produced by noise in users of music players compared to subjects who do not used them. Aim: The present study aimed to investigate the relationship between recreational hearing habits and hearing performance at 6000 Hz frequency in university students. Material and method: Fifty subjects (age range of 18-26 years), without history of otologic disorders were assessed. The CHAR questionnaire and an air conduction pure tone audiometry (125 Hz-8000 Hz) were administered to each participant. Results: Findings from pure tone audiometry demonstrated the presence of hearing scotoma at 6000 Hz frequency in fifty-two percent of subjects. Moreover, statistically significant differences were found when comparing subjects with normal threshold and subjects with threshold greater than 20 dB at 6000 Hz. This was related to years and intensity of noise exposure. Conclusion: Recreational noise exposure may cause hearing loss in early stages of lifespan. Prevention strategies to avoid early hearing loss in young subjects are required.
