Abstract
A receiver receives an acoustic wave in an atmospheric pressure measuring apparatus. Since a variation in the intensity of an acoustic wave reflects a variation in the atmospheric pressure, the atmospheric pressure can be measured based on the intensity of the acoustic wave received at the receiver. The atmospheric pressure can in this manner easily be measured with a simplified structure.
