This book is a very useful reference work for the researchers of computer science or other science streams. It specially focuses on the noise power spectrum and frequency distribution due to industries and industrial activities. It also covers the impact of noise on human beings and its surroundings as well. The Special Computer Algorithm and Programs are developed and implemented for converting time domain data into frequency domain and analyzed. The standard electronic devices are employed for the measurements of noise levels. Though the frequency spectrum of noise has adverse effects on human beings and surroundings, yet very few efforts have been taken to overcome this problem in terms of computer science and technology. This book focuses specially on it. In this book we have explored the details of noise from very basic concepts to the industrial level noise, frequency distribution of industrial noise and different types of noise such as low frequency and high frequency noise, its exposure time and effects on surroundings.
