Noise Power Spectrum for Firecrackers

Abstract

Frequency of noise can affect human beings in different ways. The sound of firecrackers is a type of intensive impulsive noise, which is hazardous. In this paper, the noise produced by firecrackers during celebration festivals in Aurangabad (M.S.), India is measured. The noise is analyzed from the study of power spectra for different types of firecrackers. Noise measurements of firecrackers show that they produce high sound pressure peak levels at their characteristics frequencies. Plots of noise power versus frequency for different crackers are presented and the inferences are discussed. Typical firecracker peak noise levels are given.

Case Study from West Bengal, India: Management of Noise Levels During Festival Time in Kolkata and Howrah Municipal Corporation Areas from 2002 to 2011

“…Various statistical analyses were carried out to examine the monitored data. Results revealed a strong association between the noise levels and industrial activities. Patange, Khan, Behere, and Shaikh () measured the noise levels generated by different types of firecrackers during festivals in the city of Aurangabad. The noise level was measured from the bursting of different types of firecrackers separately and inferences were reported thereafter. Vanadeep and Krishnaiah () investigated the monthly ambient noise levels of residential areas in and around the city of Tirupati in the Indian state of Andhra Pradesh at six locations from January 2009 to December 2010.…”
