A New Method of Calculating Radiation Impedance for Vibrating Surface with Finite Baffle

Moojoon Kim, Chun-Duck Kim, Kanglyeol Ha

Abstract

In this paper, by defining a vibrating surface to be a set of small point sources, a new calculation method for the rectangular vibrating surface with a finite baffle is suggested by considering the effect of the finite baffle on the source strength of each point source. As an example, the variation in self-radiation impedance for a rectangular vibrating surface is calculated based on the size of the baffle.
