摘要

The enhancement of operating performance in the industry is directly related with the provision of proper working environment to the workers. The studies conducted about work safety and the improvement of working conditions reveals that one of the factors influencing the labour motivation of workers is the noise in the working environment. In literature, noise is defined as the jarring sound [1-3]. While the sound is described as a measurable objective term, noise is however defined as a subjective term. The qualification of sound as a noise changes from person to person. In today's rapidly growing cities, with the expansion of residence and industrial zones, the increase of traffic intensity, and with the more inclusion of electrical appliances and mechanical devices in our life, the factors causing noise rise [1]. Noise is also particularly disturbing in the working environment of workers as well as in intense traffic, and the health of people working all day in a noisy environment is endangered.
