Abstract
A recorder with thermoacoustic sound wave generator is described. It was developed for introduction to "Thermoacousitc phenomena" and exhibition of the 99' youngster's science festival in Chiba. It is constructed of a resonance tube, which has 7 holes on its side wall for generating one octave sound waves, from C_1 of 65.4Hz to C_2 of 130.8Hz, stack and heat exchangers. It is ascertained that generated sound wave frequency is influenced by temperature inside the resonance tube and sound pressure level is affected by hole position on its side wall. It sufficient operated and is useful for the youngsters to enlighten the science interest.
