Resumen
This research was carried out with in growing and finishing facilities of swine housing with the objective to evaluate and compare the noise level emitted by the animals mainly during feeding and noise level from other sources, and estimate the occupational risk exposition of workers. The evaluation was made using noise level equipment and measurement as indicated in NR-15 norm located at 1.50 m of height, corresponding to the mean height of the worker's ear. Four swine housings were evaluated. The statistical analysis was done using fatorial design and mean test. The results indicated significant differences at 1% probability level among the four housings. The mean noise level was 65 dB(A) and 70 dB(A) for growing and finished housing respectively, within the limits allowed in the NR15 norm (85 dB(A)) for a daily working of 8 h. Considering the peak noise level observed during feeding and other task schedule mainly finishing swine housing ear protection is recommended. There was also a tendency for the noise level to increase as thermal conditions became more unconfortable. 11 4 436 440 Brasil. Consolidação das leis do trabalho. 23.ed.
