This report outlines deals with the method used of estimate sound radiation levels at a distant point by using the sound propagation characteristics and the volume velocity of the sound source. Radiation sound levels far from a vibrating source are estimated using the reciprocity theorem and an experimental model of rectangular diaphragm elements as the sound source, and by summing the levels of sound radiated from all the vibrating elements. Sound propagation characteristics of the space are obtained by reciprocally radiating a sound from a speaker located at the measuring point and measuring the sound pressure levels in the proximity of the vibrating source.
