EVALUATION OF THE ENVIRONMENTAL NOISE LEVEL OF MEHSANA CITY AND THE STUDY OF SOUND ABSORPTION COEFFICIENT OF WOOD OF SELECTED TREES TO CONTROL NOISE LEVEL

P.B. VYAS AND J.N. KHATRI

Abstract

The objective of the research is to study the environmental noise pollution as well as to find out appropriate absorption coefficient of wood (trees) which minimizes the noise pollution by the plantation of such type of selected trees along the road side and provide green belt around appropriate Buildings, Schools, Collages, Hospitals, Industries, etc. The noise level measurements were made for five minutes in dB at selected places and source of the noise pollutant and compared with selected permissible values of CPCB, India. The sound absorption of coefficient of Udumbara (Ficus glomerata) is greater 0.0235 to 0.0335, thus spongy wood is more useful to reduce the noise pollution.
