A more practical two-sensor acoustic power measurement method is applied to the measurement of sound power of thermoacoustic refrigerator. The characteristics of the sound pressure and sound power of the refrigerator with frequency are analyzed and studied. The results obtained by using the network model and The experimental results can be well matched. This study is also validated and applied to the simulation program of thermoacoustic heat engine network and the two-sensor acoustic power measurement method developed by the author.
