ThesisItem Open Access Study of noise pollution in localities of Hisar and its impact on human health(CCSHAU, Hisar, 2021-07) Gaurav; Sridevi TallapragadaNoise is regarded as a crucial environmental issue and there are various adverse health effects associated with it such as anxiety, depression, sleep disturbance, etc. The present study was carried out to perform zone-wise analysis of noise pollution in Hisar and study its impact on the residents residing in the selected zones through a questionnaire. Noise monitoring was done for day peak & off-peak hours and night hours in four major zones of Hisar i.e., Industrial, Commercial, Residential and Silent zone and the noise levels obtained were compared with the permissible values for ambient noise levels prescribed by CPCB. Noise pollution indices i.e., Noise Climate (NC) and Noise Pollution Level (Lnp) were also computed for all four zones. The noise levels of industrial zone were found within the permissible limits during both peak, off-peak and night hours i.e., 71.1, 69.9 & 68.5 dB respectively, whereas the noise levels of commercial, residential and silent zones were found exceeding the permissible limits. The change in the apparent loudness with the change in the noise level and vehicular count was also monitored in each zone. Evaluation of personal protective equipment that was being used in the industries in Hisar for protection against noise was also carried out. Results clearly indicated the alarming situation of noise pollution in Hisar and manifest the importance of reviewing the policies over environmental noise.
