Abstract:
A calibration device for calibrating a dynamic pressure sensor includes a power/control box and a portable calibration head disposed in electrical communication with the power/control box. The portable calibration head may include a calibration head housing having a housing opening and a speaker provided in the calibration head housing and communicating with the housing opening. The power/control box may be configured to induce emission of an acoustic calibration signal from the speaker of the calibration head.
