Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for evaluating sound insulation performance between adjacent chambers and a selected side wall capable of calculating and evaluating quantitatively the sound insulation performance of the side wall by calculating a side wall solid propagation sound between the adjacent chambers as a vibration acceleration level propagating inside the side wall. SOLUTION: When evaluating the sound insulation performance between adjacent chambers enclosed by the side wall 4 intersected with a door boundary wall 3, the sound pressure level of a propagated side wall solid propagation sound (a symbol of a trancated chevron shape) is calculated as a sound pressure level determined from the sound pressure of a sound source chamber 1 after entering the side wall 4 on the sound source chamber side, being propagated inside the side wall 4 with internal damping, and being radiated from the side wall 4 on the sound receiving chamber 2 side, and synthesized quantitatively with a direct transmission sound through the door boundary wall, to thereby calculate the sound pressure level in the sound receiving chamber. Hereby, the sound insulation performance between the adjacent chambers is calculated and evaluated quantitatively.
