超低周波音の到来方向識別の試み

－加速度センサを用いた方法－

This study proposes a new method for identifying the arrival direction of infrasound. A board in air vibrates due to infrasound. The magnitude of vibration increases when the intersecting direction of the board and the source direction of the sound are the same. Therefore, we are able to identify source direction of infrasound by measuring the vibration of boards which are placed in different directions. In this study, we attached vibration pickups to each board and measured the vibration of the different boards. The experimental results found that the source direction of infrasound can be identified in the range of ±10degrees.
