Abstract
The paper considers the heat transfer and liquid motion influence on the propagation of acoustic disturbances in gas-liquid foam. It has been shown that the attenuation decrement consists of two parts: Thermal and viscous, which relative intensity is defined by foam dispersion a0 (size of foam cell). When a0 < a *0 , the signal dissipation, to a great degree is caused by liquid motion, it is possible to neglect the heat transfer. When a0 > a *0 the thermal processes define attenuation and one can ignore the liquid motion.
