摘要：
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.
