Abstract : Noise-induced hearing loss (NIHL) is a hearing loss that develops gradually due to prolonged exposure to excessive intensity noise and usually comes from the work environment. This study was a retrospective descriptive study using medical record data at Neurotology Clinic, Dr. Soetomo Hospital, Surabaya, Indonesia, from January 2016 to December 2020. Male patients with NIHL were more than female patients. The ratio of male to female patients was 1.92 :1. Most NIHL patients were in 41-50 years age group, as many as 12 patients (31.58%). NIHL patients as many as 18 patients (47.37%) had a chief complaint of tinnitus, while 20 patients (52.63%) had complaints of hearing loss. Most of the patients' occupations were traders of 8 patients (21.05%). The length of work of NIHL patients showed that those who worked for less than 10 years were 12 patients (31.58%). The mean notch frequency typical of NIHL patients was found in 15 patients (39.47%) with a frequency of 4000 Hz, and 23 patients (60.53%) with a frequency of 6000 Hz, with a decrease in intensity of 59.50 dB and 65.54 dB. The chief complaint was tinnitus, which was more common than hearing loss. Most of the patients' occupations was traders, with the majority of patients had been working more than 10 years. Most hearing loss was mild with a characteristic notch frequency occurring more at 6000 Hz than 4000 Hz.
