Abstract

The spatial and temporal distribution of acoustic pressure in an ultrasonic field in a liquid medium is commonly determined using miniature ultrasonic hydrophones. These devices are not absolute measurement instruments and require calibration. The purpose of this part is to specify those calibration methods to be used in determining the response of a hydrophone in the ultrasonic range, i.e. above 20 kHz up to a frequency of 40 MHz.
