Noise is defined as any unwanted sound that you do not need or want to hear. Loud noise can also create physical and psychological stress, reduce productivity, interfere with communication and concentration, and contribute to workplace accidents and injuries by making it difficult to hear warning signals. There are number of locations in every old Thermal Power Plant who is responsible to create noise. Different Coal based Thermal Power Plants were selected from the decade 1980 to 2011. In thermal power plant, most of the section can create high decibel noise i.e. 90 dB to 95 dB and it is hazardous to human health. Sound becomes undesirable when it disturbs the normal activities such as working, sleeping, and during conversations it can also cause memory loss, severe depression, and panic attacks. ISO 1999 standard describes a model for the prediction of the distribution of the hearing loss at a given frequency, in a population of a given age, after a certain number of years of exposure to a LEX, 8h level. Use of a three Level risk scale provides guidance for the assessment of the Level of risk. Level 1- Daily noise exposure level definitely below 80 dB (A), which has a minimal risk of noise induced hearing loss. Level 2- Intermediate risk, lying between 80-85 dB (A) having some risk of noise induced hearing losses Level 3- Daily noise exposure level definitely over 85 dB (A), the value for which it is recommended that Technical measures should be taken to reduce noise exposure. The Risk evaluation due to Noise generation and the estimation of unaccepted level has been computed. The potential hazard shall be controlled to eliminate the occupational health effects to the exposed persons either in acute or chronic sense.
