Abstract

Noise-Induced Hearing Loss (NIHL) is sensorineural deafness resulting from prolonged exposure to loud noise. In the military environment, personnel with NIHL are often found. One of the professions that are at risk for NIHL is an aviator. Some of the factors that influence the degree of deafness are age and length of work. This research is a descriptive quantitative observational study with a cross-sectional design. The research subjects were Squadron 11/Attack helicopter pilots at Achmad Yani Air Base, Semarang, totaling 32 pilots, which were taken from medical record data. Sampling was done by total sampling. The data obtained were processed using SPSS and grouped into tables accompanied by descriptive explanations of each characteristic. The audiogram results showed that 32 pilots were normal, across all age and length of service categories. This result is due to the appropriate use of hearing protection device (HPD), in the form of a helmet that reduces noise up to 14 dB at 250 Hz, 21 dB at 1000 Hz, 26 dB at 2000 Hz, 37 dB at 4000 Hz, and 42 dB at a frequency of 8000 Hz, which pilots use. The pilot's working time is relatively short with a flight training schedule only

2 times a week and a flight time of around 2-3 hours. The conclusions of the study showed a description of normal hearing function in all Squadron 11/Attack helicopter pilots, based on age and length of service.
