The results of the noise measurements obtained in three foundries, two of cast-iron and one of aluminium, are reported. Because of noise level variations, a level recorder and a statistical distribution analyzer have been used in addition to a sound level meter, and thus equivalent continuous sound levels (Leq) both with factor q = 3 (European Code) and with factor q = 5 (OSHA) have been calculated. The results obtained with these two different criteria of evaluation are discussed.
