Sound transmission through a flat plate and a cylindrical shell was studied both theoretically and experimentally. The theory consisted of using statistical energy analysis (SEA) to predict the transmission loss of each structure. The experimental part included the use of sound pressure levels obtained using microphones and of sound intensity using a sound intensity probe to calculate sound transmission loss. Results, both theoretical and experimental, were then compared to draw conclusions concerning the best way to measure sound transmission through structures and how reliable the theory is, the behavior of structures made of the same material but of different shapes was also of concern in this study.
