Abstract

Micro Cellular Plastics create a sensation at polymer industrial for lowering product cost & overcoming a lowering of mechanical intensity. This research based on the experiment of sound absorption & transmission characteristics inquire into acoustical properties of Micro Cellular Plastics in low frequency range. TL difference of MCPs & Soild materials was defined as cell effect. Also, cell effect is expressed by sound reflection & sound absorption.
