Abstract

In India the concept of categorization of different areas is still in the premature stage in most of the cities. Only few metro cities like New Delhi, Mumbai, and Bangalore etc. are in process to adopt the idea. The noise regulations and standards in India were introduced around a decade back and the standards were given as per the four different areas like residential, commercial, industrial and sensitive areas. The problem of noise pollution is not very clear to all because of the peculiar nature of it of being without weight and unlike other pollutants you cannot see it. The impact is also slow in most of the cases. In this paper an attempt has been made to give a picture of noise level of a city which was supposed to be a dream destination of retired people for their rest of life, a suitable location for a writer to write a poetry or story. The noise level is recorded for day and night to compare it with the national noise level standard. The value of noise levels in recorded 20 locations of the city varies from 45dB to 86 dB whereas Leq values ranges from 50dB to 79 dB and SEL values are on the higher side at all locations.
