When a train enters a tunnel, a pressure wave is generated. This pressure wave propagates in the tunnel and emits as micro pressure wave at the opposite tunnel exit. This pressure wave could appear as a sound pulse in a particular environment and cause hazardous effects on the environment near the tunnel exit. When planning tunnels, it is necessary to take appropriate measures to reduce the magnitude of the micro pressure wave. In this study, we investigated the existing micro pressure wave management standards and studied the signal processing method and the sound evaluation method which were used in setting the appropriate management standard for the evaluation of the micro pressure wave.
