A low-medium frequency sound velocity measurement device and measurement result via comparison method

Abstract

Accurate calibration, of acoustic velocity in water is essential in acoustic measurement. In order to measure the acoustic velocity in water, a sound propagation delay detection device based on correlation method is designed. This paper gives a detailed introduction of this medium and low frequency sound velocity measurement device and the results of sound velocity measurement obtained by comparative method. This device can be used for sound velocity detection of other media in water.
