SUMMARY OF BASIC PRINCIPLES OF ACOUSTIC THEORY

Abstract

Several studies are reported on noise pollution literature, with many different approaches. However, there are evident in such publications fundamentals of acoustic theory, aiming at a more appropriate characterization of sound phenomenon. This paper aims to provide an alternative source of consultation for those faced with the fragmented and too much information, sometimes an obstacle to understanding main physical aspects of noise pollution. This paper to present and discuss concepts concerning the sound properties, principles of sound propagation and related phenomena.
