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 Web of Sound listening to them is humming in a room where another dozen people are humming also, in a constant pitch, never varying, unchanging." Allmusic's Joe Viglione suggested that "A Web of Sound" also influenced such artists as Iggy Pop and The Stooges and Alice Cooper. Stewart Mason, also of Allmusic, remarked that the album blended "the snotty aggression of ["The Seeds"] a bit with some heavier psychedelic flourishes." Writer Malcolm Russell described "A Web of Sound" as being "more adventurous" than the band's debut album, and said it "brimmed with scratchy mid-60s classics." Don Jacobson of "The Beachwood Reporter" called it
