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
Sound of a Woman a slowed down version, with a video showing her and others, slowly revealed to be without clothes, to express "raw emotions". Kiesza described "Sound of a Woman" as having grunge, rock, and folk influences in addition to her usual house or dance genre and that some songs on the album would be surprising to people.
