Diesel Engineによる聴器障害

HEARING DISTURBANCE DUE TO DIESEL ENGINE NOISES

　Ⅰ．緒言

　騒音職場，それは文明の発達に伴つて必然的に増してきたものであつて，これからもなおこのような職場の増加は避けることができない。著者らはこの数年にわたり，長崎海上保安部の機関部勤務職員の聴力検査を行ない，ここにおいてもすでに音響外傷受傷者が存在することを見出したので報告する。

Hearing tests were conducted among perso-ns who work in the engine room of the coast guard ships. A considerable number of exami-nees were found to be affected with deafness due to noise. By study in analysis of the recorded noise of the engine room, it was concluded that the noise from the diesel engi-ne was the causative factor in production of noise deafness.
