This paper is the result of investigations made on aluminium panel to understand the effect of varying thickness on sound transmission loss and noise level. Aluminium panel modeled using CATIA V5 and simulated in COMSOL to investigate the acoustic pressurized frequency –amplitude response for 8mm and 12mm aluminium panel and corresponding sound transmission loss is calculated using engineering noise control simulator (ENC).Theoretical values of sound transmission loss is matched with ENC simulator values. The observation has made that,if amplitude is more; noise is more, eventually corresponding sound transmission loss is less at given frequency and thickness.12mm aluminium panel is found to be better noise attenuation than 8mm aluminium panel which can be viewed in the result section.
