Abstract

Abstract: Noise absorption and transmission property of materials is of great importance in order to determine the amount of noise transmitted from source to receiver. Unwanted noise can cause various biological and psychological effects to humans and other organisms in nature. This paper deals with the experimental study on noise absorbing and deflecting ability of various available materials. These materials could be utilized in industrial complexes and building construction applications for noise level reduction purposes. The materials such as glass, plywood, thermocol (scientifically known as polystyrene), fiber plastic sheet and coconut fiber sheet have been used in the experiment as a noise barrier. Through experimental analysis, the reduction noise level was obtained in terms of decibel (dB), sound power level and loss of sound energy using hand held noise analyzer. The finding suggests that thermocol has the best sound absorbing capacity at medium to low sound pressure levels, whereas glass has the best sound absorbing capacity at high sound pressure levels.
