The objectives of the research are t o identify the noise sources and noise level exposure inside C130H aircraft's hangar; to produce noise mapping; to identify hearing status of C130H aircraft maintenance crews (MC); and suggesting the noise control measure that can be applied. A field survey on noise level by using a digital sound level meter and producing noise mapping. A hearing testing among 63 MC was carried out in Institute of Aviation Medicine, Royal Malaysian Air Force (RMAF). Reviewing the literature and analyzing some control measures to be taken. Hearing test result shown 41.2% of the MC are having hearing impairment. The highest noise level at the central of the hangar is 92.2 dBA (day-time) and 94.2 dBA (night-time) when there is a C130H aircraft starting its engine at 50 meters from the central of the hangar, 95.3 dBA (day-time) and 97.3 dBA (night-time) when there is a C130H aircraft Engine Ground Run at 150 meters from the central of the hangar. Besides, Auxiliary Power Unit is producing the highest noise level which is 125.7 dBA (day-time) and 127.7 dBA (night-time). The application of Personal Protective Equipment (PPE) is the very likely control measure to be taken while engineering control is very costly but can be considered. Since noise is recognized as a hazard, hearing protection as PPE will not be the ultimate solution as a control measure. Hence, the Engineering Control must be identified and studied to be implemented as an ultimate solution to control the noise hazard in long term duration.
