Comprehensive Control of the Noise Occupational Hazard in

Jan 01, 2012 When noise level is up to 100 ~ 105dB, the detection rate of deaf induced by occupational noise is up to 52%, and hearing damage detection rate of high-frequency noise is nearly 60%. Long-term working in high-noise environments of the cement plant, influence of noise on neurasthenia syndrome is obvious, which causes insomnia, dizziness

Noise levels can be reduced through the use of some or all of the simple and practical methods discussed below. These methods focus on three basic approaches to controlling noise: noise source controls, noise path controls, and hearing protection.Noise source controls, which typically consist of engineering controls, provide the most effective means of protection, since they actually reduce
