Abstract
The transmission of sound from air to water is the subject of a study which is reported here. The general problem is one which has been reported in the literature primarily as a theoretical and mathematical analysis. The transmission across a plane interface of sound waves with a curved wavefront has, as a consequence, been understood for some years. However, it appears that an experimental confirmation of the findings, particularly in relation to the effects which occur at and close to the critical angle, has not been presented previously. The report supplies experimental information which appears to support the established theory except at large angles of incidence. The data which is presented was obtained from experiments in tank of water, with a semi-anechoic lining, using a St. Clair generator operating at approximately 37 kHz as a source.
