| Outline of Final Research Achievements |
We have proposed a silencer of the new principles unprecedented applying a thermoacoustic effect. With thermoacoustic effect, a mutual energy conversion of thermal energy and sound energy is enable. It has proposed to reduce the sound energy by utilizing the thermoacoustic effect from the waste heat. To prepare a prototype of thermoacoustic silencer, it was conducted principle confirmatory experiments. It was possible to confirm the reduction in the order of ten percent in certain conditions. In addition, we conducted experiments that assume the muffler of the automobile, we got valid experimental results.
