PURPOSE: A correcting system and method of air sound wave observation sensor using pneumatic pressure are provided to enhance the precision of an analysis calculating a size of a signal source and a position decision of air sound wave observation data by correcting data actually observing. CONSTITUTION: A correcting system of air sound wave observation sensor using pneumatic pressure comprises a pneumatic pressure pump(100), a first electronic control valve(150), a first pneumatic pressure storage tank(200), a first pressure indicator(250), a second electronic control valve(300), a first shutoff valve(350), a second pneumatic pressure storage tank(400), a second pressure indicating control indicator(450), a second shutoff valve(500), a chamber(550), and a recorder(600). The pneumatic pressure pump generates pneumatic pressure. The first electronic control valve stores a set amount of the pneumatic pressure generated by the pneumatic pressure pump up in the first pneumatic pressure storage tank. The first pneumatic pressure storage tank stores the pneumatic pressure has passed through the first electronic control valve. The first pressure indicator indicates the pneumatic pressure stored in the first pneumatic pressure storage tank. The second electronic control valve supplies the pneumatic pressure controlled by control signals to the second pneumatic pressure storage tank or the chamber when a demanded amount of the pneumatic pressure is confirmed. The first shutoff valve shuts out or supplies the pneumatic pressure supplied to the second pneumatic pressure storage tank by the control signals. The second pneumatic pressure storage tank stores the pneumatic pressure has passed through the first shutoff valve up. The second pressure indicator indicates the pneumatic pressure stored in the second pneumatic pressure storage tank. The second shutoff valve shuts out or supplies the pneumatic pressure supplied to the chamber by the control signals. |
