“…When the temperature is 20 ο C the properties of the air are ρ 0 = 1.21kg/m 3 and c = 343m/ s. The frequencies adopted in the computation are only the frequencies in the audible frequency range. The damping coefficients adopted in the computation can be expressed as c d = ρhω/100π which are obtained from experiments (1,12,15). According to the method described in equation (26), these rectangular plates were discretized into 60 elements for calculating and the area of each element is equal.…”

The influence of boundary conditions on the sound radiation characteristic from rectangular plates is studied in this paper. Using an analytical method, the transverse displacement response of vibrating rectangular plates is presented. Some numerical experiments are also done. Five different types of boundary conditions are analyzed and calculated as examples for comparing the influence of different boundary conditions. Rectangular plates under different force points and different thicknesses are also studied for further verifying the influence of boundary conditions.

This paper describes the effect of boundary conditions on sound loudness radiated from rectangular plates. Based on the Rayleigh integral, the Zwicker's loudness model and the dynamic response of the plates, the sound loudness radiated from vibrating plates and the effects of simple support, clamped support and free support on sound loudness are separately studied. The effects of boundary conditions on sound intensity level, sound intensity density and critical-band level are also studied, taking the frequency selectivity of human hearing into account. The transformation from sound intensity level to sound loudness radiated from rectangular plates, due to the frequency-selectivity characteristics of human hearing, is also illustrated.
