Abstract: The app licat ion of two2senso rmethod to themeasurement of acoust ic pow er of themoacoust ic refeigerato r is p resented in th is paper. The frequency characterist ics of acoust ic p ressure and acoust ic pow er of thermoacoust ic refrigerato r discussed here are invest igated and analyzed. The results calculated w ith netwo rk model are in good a2
greement w ith that of experiments. These studied results in th is paper also have p rovided verificat ions fo r the net2 wo rk p rogram developed by autho rs fo r thermoacousitc heat engines and refrigerato rs, and fo r the method of two2 senso r to measure acoust ic pow er of p resent thermoacoust ic refrigerato r.
