Refraction (sound) Refraction (sound) Refraction, in acoustics, comparable to the refraction of electromagnetic radiation, is the bending of sound propagation trajectories (rays) in inhomogeneous elastic media (gases, liquids, and solids) in which the wave velocity is a function of spatial coordinates. Bending of acoustic rays in layered inhomogeneous media occurs towards a layer with a smaller sound velocity. This effect is responsible for guided propagation of sound waves over long distances in the ocean and in the atmosphere. In the atmosphere, vertical gradients of wind speed and temperature lead to refraction. The wind speed is usually increasing with height, which leads to
Son of a Son of a Sailor (song) melody has changed somewhat. Nadirah Shakoor sings the second half of the second verse. A couple of corners were cut, particularly the final chorus and outro. This is the version that Buffett continues to play, and is what the re-recording on "" and the sound board live albums sound like.
