| Abstract: | Two new medium parameters related to acoustic attenuation are introduced and an acoustic propagation coefficient is defined. An aconstic wave equation for a viscous and thermo-diffusive homogeneous medium is derived. The effect of frequency and medium parameters on acoustic attenuation, phase shift and speed of acoustic wave are analyzed. The conclusions are capable of giving a satisfactory explanation to the experimental results in relevant literature. |
