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 fun this sound was -- and is." Julia Leconte of "NOW Magazine" noticed that "at first, [...] Kiesza's debut album seems overwrought [...] but eventually, subtleties and variety emerge" and felt that "Kiesza's so much better when she reels back her impressively ranging vocals to buttery." Chris Chiu of "The Silhouette" wrote that the album "offers the same intensity and sound that made her an instant hit and proved her overwhelming potential," but also that it "suffers from a bit of an identity crisis." Larry Fitzmaurice of Pitchfork Media noted that "Sound of a Woman" "fails to spark, as its
