Abstract

Sound is simply a kind energy which sprawls to environment as waves. Sound changes pressure at air, water etc. which this detected by ears as sound. At the other hand noise is a kind of sound which is unpleasant, and undesirable for humans. In automotive industry, noise effects drivers and passengers comfort directly. Because of that, automotive manufacturers consider noise insulation in automobiles as an important factor for quality. Ethylene Propylene Diene Monomer Rubber (EPDM), Natural Rubber (NR) and Nitrile Rubber (NBR) are one of the most used insulation materials in automotive industry. In this study, EPDM, NR and NBR materials sound absorption coefficient and sound transmission loss are measured with impedance tube for investigate these materials as insulation part placed between passenger cabin and engine side on shifter mechanisms. Measurements repeated three times and results showed at graphics. Results are which obtained from tests are presented systematically in this study. In conclusion, s tudy results showed that EPDM is slightly better than NR and NBR as material of noise insulation part at shifter mechanisms.
