Article Preview

The acousic comfort of woodworking wide belt sander has been evaluation by impacts of on-the-spot noise and the main single frequency noise of woodworking machine-sander on workers’ physiological and psychological load from the aspect of the noise influencing heart rate.Experimental noises are abstracted from the noise of the woodworking sander under the usual processing, as the noise source.The heart rate experiments are done under two states, namely the noise and the quiet in the laboratory.Finally, the change of human load is analyzed on the basis of the heart rate.The method of heart rate instead of traditional noise level puts more emphasis on the workers’ psychological load than traditional methods.The noise influence on human body is discussed from the aspects of both psychology and physiology. The results show that the influence of the 67 Hz noise on human body’s load is the greater than the other noises in the noise-exposed period and that of the 1422 Hz noise is the greatest and most difficult to recover in the experimental recovery course.
