Abstract
Noise is broadly defined as unwanted sound that generally prevents people from performing at maximum ability and efficiency. Following air and water pollution, noise pollution is the third most critical environmental subject. Noise can be industrial noise, military noise, traffic noise, other kinds of environmental sourced noises, etc. Exposing noise by such ways can result in increased nervous tension with associated psychological effects, some impairments to the audio-sensory mechanism, and lead to premature and/or permanent loss of hearing. Statistics show that among worldwide, exposing the high doses of noise, hearing loss and tinnitus are significant public health issues and the prevalence of these conditions among employees in industry is significantly greater than the general public. This study is a compilation of literature which presents noisy workplaces, negative effects of noise on workers' health and the prevention plan of negative effects. In this research, the current situation about noise exposure in workplaces and its negative effects on workers are presented according to the statics and literature in Turkey and around world. After drawing the present frame of the picture, some recommendations will be given in order to prevent noise exposure and its negative side effects in industry.
Highlights
One of the most widespread workplace hazards is noise
During the 18th century, the occupational hygienist Ramazzini pointed out the ears of copper workers are suffered from noise dangerously
The employees who expose these types of noise generally do not aware of the risk
Summary
Due to the exposure of this hazard, hearing loss is the main occupational disease. Some employees in some special occupations expose to noise 24h or even more. Noise can be grouped into four types These are: ambient, impulsive, non-steady and steady ones. Non-steady noise has level shifts significantly during the period of observation. Steady type of noise has negligibly small fluctuations of level within the period of observation. The industrial noise exposure can be counted as impulsive or non-steady types of noise especially in heavy industry. The employees who expose these types of noise generally do not aware of the risk. This situation makes the condition even more risky
