UNLABELLED: According to the World Health Organization, significant hearing loss in young people exposed to recreational acoustic trauma has become a public health issue.
OBJECTIVE: To describe the clinical and audiological profile of individuals with Sudden Sensorineural Hearing Loss (SSNHL) exposed to recreational noise.
METHODS: A prospective cohort study was conducted involving outpatients with SSNHL and a history of exposure to acute recreational noise. Follow-up occurred weekly in the first month, then monthly for up to six months of follow-up. All were treated with oral corticosteroids with prednisone 1 mg/kg/day, followed by a gradual dose reduction of 20 mg every 7-days until complete withdrawal of the medication.
RESULTS: Twelve individuals were included, 8 (66.7%) males, with a mean age of 24.16-years. 58.3% of the individuals had binaural involvement. Only one patient had permanent profound hearing loss, with no sign of recovery after treatment. All had associated tinnitus. Half of the participants reported having used recreational drugs, and the type of exposure varied from New Year's Eve parties, funk and electronic music, concerts and games in stadiums. Regarding the duration of exposure and the distance from the sound source, most reported a time of 3-5 h, with a short distance from the source.
DISCUSSION: Recreational noise exposures have the potential to increase the risk of hearing loss in individuals outside of the workplace. Data such as sex, age group and the most prevalent type of noise exposure in these cases reported in this study corroborate the findings in the literature. Regarding the persistence of hearing loss after treatment, the outcome was varied, and the studies are still controversial.
CONCLUSION: There is an association between exposure to recreational noise and SSNHL, and the epidemiological profile of patients affected by this condition is marked by adolescents and young male adults with unilateral and binaural involvement, severe degree of hearing loss at onset, and commonly associated with the use of recreational drugs, risking permanent hearing damage.
LEVEL OF EVIDENCE: 3 (OCEBM Levels of Evidence Working Group*. "The Oxford 2011 Levels of Evidence").
