<br />
<br />
<br />
<br />
The sea, together with its boundaries, forms a remarkably complex medium for the propagation of sound. It possesses an internal structure and a peculiar upper and lower surface which create many diverse effects upon the sound emmited from an underwater projector. <br />
<br />
<br />
<br />
<br />
The ocean surface varies from glossy smooth reflector to a very rough and turbulent surface that scatters sound in a random fashion. In spite of this rich variety of detailed characteristics, it is possible to recognize predictable patterns related to environmental conditions and geographic locations. Acoustic loss data for the boundaries, derived from a combination of experience and theoretical considerations, cover the expected ranges of wind speed, grazing angles, bottom characterictics, and frequencies. <br />
<br />
<br />
<br />
<br />
Because of that, in traveling through the sea, an underwater sound signal becomes delayed, distorted, and weakened. Transmission loss expresses the magnitude of one of the many phenomena associated with sound propagation in the sea. |
