Abstract:

In industrial society there is the problem of noise pollution. Exposure to excessive noise may produce a variety of traumas, starting with an unpleasant feeling and ending with a permanent hearing loss. Environmental acoustics deals with noise control, trying to produce quieter machines or to insulate better the buildings. In workshops for finishing gray iron castings the noise power level is very high causing many ill absences. This paper presents the noise problem in a fettling workshops for gray iron castings of S.C. "Robinete Industriale" from Bacau and the ways to prevent the effects of noise exposure.
