    Abstract

    Our group has produced the system whereby noise is exchanged for thermal energy, and been able to extract the heat from the noise. Noise is usually absorbed by some substance and finally exchanged for thermal energy. Therefore this system has advantage that it never produces additional heat loads in a global environment. It is also very unique that energy of noise is actively consumed by the energy exchange. Noise is an unusual type of energy because waste of noise is encouraged. It is thought that noise is applied as an alternative energy. This system, however, has disadvantage that energy transformed is very little, because energy of noise is little. Therefore, the system which extracted the energy of noise from very wide area was proposed. It consisted of many thermoacoustic tubes. It is difficult to sum the thermal energy which was transformed by the many tubes if energy after exchanging is heat. The system whereby energy of noise is exchanged to electric energy has been produced, although we understand that the efficiency of exchange is reduced. Thermal energy which was transformed by thermoacoustic tubes was transformed into electric energy by Peltier devices again. Though electric energy which was transformed by only one apparatus is very little, it is easy to sum the energy which was transformed by many apparatus. We imagine that noise barriers which consist of the numerous apparatus were placed beside the railroads or highways. The barriers absorb sound energy of the traffic noise, and transform into electric energy. Several apparatus which transform the energy of noise into electric energy have been prepared and investigated whether electric energy which was transformed by these apparatus can be summed up. It has verified that the total wattage which was transformed is approximately proportional to the number of the apparatus used.
