whereas the sound attenuates underwater at 100 Hz at about 0.001 dB per
kiloyard.
2.6 Sound Propagation with Obstacles
2.6.1 Refraction
Refraction is the bending of sound waves. The transmission of sound
through the water with various temperature layers and the application of
Snell’s law have been treated in this chapter. Transmission of sound through
water is probably the most extensive practical application of refraction in
acoustics.
2.6.2 Reflection and Transmission
There are many practical problems related to reection and transmission ...
