Abstract: Noise is harsh, disagreeable, irritable and unwanted sound which may cause irritation and annoyance to the public as well as to the surroundings. It is a global challenge as it is consider one of the major environmental issues in the present era.In this paper studies have been made for finding variations for noise exposure level, noise descriptors and the comparative study of the noise exposure level (Lden), average day night noise levelLdn and other noise descriptor such as L10, L50, L90& Leqat four selected location in metropolitan city Lucknow viz. Aliganj, Jankipuram, Indiranagar and Krishnanagar on pre diwali and on diwali day. The sampling was done at four locations on the pre diwali day and the diwali day from 06:00 to 10:00(daytime), 18:00 to 22:00(evening time) and 23:00 to 24:00(night time). Data was taken at an interval of 15 second continuously for the 15 minutes and again for the next 15 minutes with the gap of 15 minutes in successive reading.The results indicates thatLeq was from 55.5dBA on pre diwali to 62dBA on diwali day at Aliganj while the Lden and Ldnwere 61.7 and 61.1 respectively on pre diwali to 70.5 dBA and 76.3 dBA respectively on the diwali day. At Krishnanagar location, variation was between 59.2dBA on pre diwali to 84.1 dBA on diwali day while the Lden and Ldnwere 65.8 and 65.2 respectively on pre diwali to 90.6 dBA and 91.6 dBA respectively on the diwali day. Variation at the site of Indiranagar shows Leq 72.1 dBA on pre diwali to 77.8 dBA on diwali day while the Lden and Ldn are 82 and 81.9 respectively on pre diwali to 87.5 dBA and 87.4 dBA on the diwali day. The variation of Leqat Jankipuram was 56.7 dBA on pre diwali to 76.8 dBA on diwali day while the Lden and Ldn are 64.2 and 63.5 respectively on pre diwali to 85.8 dBA and 85.4 dBA on the diwali day. It is observed that mostly all the noise parameters at the all study locations are beyond the prescribed limits.
