Abstract

Introduction: Noise is considered as one of the occupational risk factors which could lead to serious problem in every workplace. Hearing loss and tinnitus prevalence of military population is higher than in public Objective: To determine the effect of noise exposure level in firing range towards noise induced hearing loss among personnel in Malaysia. Methodology: A cross sectional study were carried out which is designed to ascertain the risk factors and the outcome of interest at Bukit Jugra Firing Range. The study population for this study were 80 male military personnel from different ethnic groups which is employed in different work sector throughout the military camp. The study were using questionnaire for socio demographic assessment, sound level meter for area noise survey, dosimeter for personal noise survey measurement and audiometric threshold test. Results and discussion:. A total of 72(90%) claimed that the working environment that they work on daily basis are exposed to high level of noise exposure in which only 30(37.5) use protection devices. The worker experienced hearing problem in which 26(32.5%) claimed that they have tinnitus. The Time Weighted Average (TWA) for area noise survey was at 89.3(+-1.7) dBA. The personal noise measurement that were recorded for the time period was at 90.2(+-1.5) dBA in which the peak(Lcpeak) reading for the shooting period was at 144(+-0.2). The prevalence for hearing loss was at 18.8% in which 15 persons of them have change in threshold level >25dBA. Most of them 12(15%) have hearing loss at 4000Hz for left ear. Conclusion: This study shows that noise exposure and duration of employment in the army is one of the risk factors that results in hearing loss. This can be seen whereby most of the military personnel that have hearing threshold >25dBA are exposed to loud noise and employed for longer duration of years. It is recommended that the workers are given proper instruction and training in the usage of Hearing Protection Devices.
