Refraction (sound) a downward bending of the sound rays towards the ground. The same holds if the temperature is decreasing with height. If the temperature is increasing with height (inversion) and the wind speed is low, sound rays are bend upwards. 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
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.
