Study on the effect of noise on the hearing of the SU-30 aircraft maintenance soldiers

SU-30 aircraft is a modern fighting aircraft in Vietnam. The noise of the aircraft’s engine with high frequency and intensity will have effect on the hearing of the soldiers, specially aircraft maintenance soldiers. This study was carried out to investigate the noise levels in some working areas and the effect of noise on the hearing of the Su-30 aircraft maintenance soldiers. | Journal of military pharmaco-medicine 7-2013 STUDY ON THE EFFECT OF NOISE ON THE HEARING OF THE SU-30 AIRCRAFT MAINTENAnCE SOlDIERS Nguyen Minh Phuong*; Nguyen Van Chuyen* Nguyen Van Ba: Nguyen Tung Linh* SUMMARY SU-30 aircraft is a modern fighting aircraft in Vietnam. The noise of the aircraft’s engine with high frequency and intensity will have effect on the hearing of the soldiers, specially aircraft maintenance soldiers. This study was carried out to investigate the noise levels in some working areas and the effect of noise on the hearing of the Su-30 aircraft maintenance soldiers. The results showed that the sound intensity levels in working areas of Su-30 aircraft maintenance soldiers in the airport as well as maintenance area were higher than hygienic standards. The highest sound intensity level was 120 dB. The rate of hearing loss among SU -30 aircraft maintenance soldiers was quite high (23.9%). The higher seniority, the higher rate of hearing loss and their higher level of hearing loss in SU-30 aircraft maintenance soldiers. * Key words: Noise; Hearing; Aircraft maintenance soldiers. Introduction Noise is one of the factors that cause working environmental pollution. According to accountance of the World againts noise association, there were from 1/4 to 1/3 workers have to work in working environment with high sound intensity level that can impact on the hearing of workers. In the military working condition, there are many arms in which soldiers have to work in environment with high sound intensity level such as artillery, tank, airforce, navy, corps In Air Force, the noise caused by aircraft engine with high frequency and intensity which can be harmful to the health of soldiers, specially aircraft maintenance soldiers who have to be exposed to the noise directly. SU-30 aircraft is a modern fighting aircraft in Vietnam. The investigation of the noise caused by SU-30 aircraft as well as the effect of noise on the hearing of aircraft maintenance soldiers
