This study aims at the theoretical and experimental investigation into the dependence of sound velocities and elastic moduli on intercellular space gas in fruits and vegetables.<br>It was proposed that longitudinal wave velocity of gas-dispersed medium could be determined by gas volume fraction and elastic moduli of medium. In this paper, the validity of this theorem was experimentally investigated by gas-dispersed agar gel. Although the experimental results showed that bulk modules was a dominant factor of wave velocity, Young's modulus had little influence on wave velocity. It was also clarified that dispersed gas reduced bulk modulus and thus wave velocity was decreased.
