Sonic Window in the Ocean
The transmission of sound across a plane boudnary between sea and air is considered theoretically. An analytical expression of the sound transmission coefficient for the case of oblique sound incidence is given, and the variation of the sound transmission coefficient with the angle of incidence is shown. An idealized method for decreasing the sound transmission loss across the air-sea boundary by means of an intermediate medium whose characteristic impedance is the geometric mean of the impedances of air and sea is discussed. These concepts are applied to some current problems in the area of anti-submarine warfare.
