(S6)Active Noise Control Based on Song of Insects

In order to change noises from machinery to comfortable sound, we have investigated song of singing insects such as cricket or bell-ring cricket as a reference of the comfortable sound. By measuring human brain wave when listening artificial insect song synthesized with an electronic circuit, we have been trying to reveal the influence of components of insect's song on the human feeling. In the near future, those results will be applied to the active noise control.
