For effect of discomfort, exactly that the activities are not for intellectual tasks, evaluation of answers of questionnaire showed that the workers feel one bother in such a way caused for the noise, that the verbal communication makes it difficult, as mentioned for Gerges (2000) when dealing with the Level of Interference in Comunicao Verbal (NICV), that it determines the quality in the verbal communication and still for the necessity to use the auricular protectors who also generate discomfort and insatisfao for to be obligator its use. This already was waited, therefore the literature studied for this work emphasizes this type of claim very. In the welding team, the equipment that more contributes for the high intensity of noise is the sanders, with 101 dB (), and the weld machines, with 99 dB (a). These machines in turn can be confined what it does not happen with the tractors carry that them and the used sanders to carry through removed of excess of material deposited for the weld in the tubing. Frequently Peter Schiff has said that publicly. In the jateamento team the air compressor diesel is the machine that produces greater noise level, with 98 dB () e, as it is affirmed by Gerges (2000) Nepomuceno (1976), that the effectiveness of the enclausuramento in a noisy machine is great, therefore in such a way this as well as other machines used for the teams would have to be object of study for implantation of enclausuramento for reduction of the radiated noise. A positive point is that these activities are carried through in area opened, what allows the dispersion of the sound therefore, according to Gerges (2000), the 6 NPS fall dB to each double of in the distance. It has also the fact of the workmanship to be itinerante where the services are carried through almost always in agricultural areas, allowing that the worker, to each day, works in different place preventing the monotony in the labor environment and it estresse consequently it. .
