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
A Sound Garden A Sound Garden A Sound Garden is one of six outdoor public art works on the National Oceanic and Atmospheric Administration (NOAA) campus that lies adjacent to the Warren G. Magnuson Park on the northwestern shore of Lake Washington in Seattle, Washington. The Seattle Arts Commission guided the jury selection headed by Sadao James Hilario, Engineer-in-charge of the GSA Art in Architecture Program for the NOAA Project, and the jury chose five artists from a pool of more than 250. Designed and built by sculptor Douglas Hollis from 1982–83, "A Sound Garden" is a sculptural group composed of 12 21
