||Noise aboard ships: its effects on the hearing of merchant seamen
||Bruit Ó bord des navires: son retentissement sur la fonction auditive des marins de commerce [in French]|
||1984, Vol.45, No.5, p.345-349. Illus. 6 ref.
||This study involved 222 seamen (132 of whom were engine-room workers), who spend several months every year at sea. A noise evaluation of ships has shown that important differences exist between engine rooms and other areas aboard. Audiometric examinations showed that engine-room workers, exposed throughout the day to noise levels above 90dB(A), suffered hearing impairment (with peak impairment at 4000Hz), while the other seamen, whose exposure was in the 60-85dB(A) range, suffered from premature presbycusis. The periodic nature of work aboard (3 months work/2 months vacation) and the retirement age (55 years) account for the fact that the hearing damage suffered by engine-room workers is limited, despite the very high levels of noise they are exposed to. Emphasis is on noise control aboard ships, on medical surveillance of workers at risk and on audiometric examinations of engine-workers every two years.
