Acoustic Radiation by Set of L-Jointed Vibrating Plates

Sound radiation from a L-jointed plates is investigated. Of particular interest is the acoustic pressure level at the control point at the distance of 1 m from the two plate surfaces. Two approaches were utilised, the FEM method was applied in the analysis of structural vibrations and the radiation efficiency in the analysis of acoustic phenomena. The other approach was the statistical energy analysis, referred to as SEA.
