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 Like Someone Trying Not to Make a Sound confront their fears." Liz Rosenburg, reviewing for the "Boston Globe" concluded, "It may not be for everyone, certainly not for the most timid, but it has a satisfying and haunted originality that will win its own fans." A Sound Like Someone Trying Not to Make a Sound A Sound Like Someone Trying Not to Make a Sound (Doubleday Books for Young Readers, September 28, 2004, ) is a children's picture book written by John Irving and illustrated by Tatjana Hauptmann. The title was originally used for a children's book written by a fictional character (Ted Cole) in Irving's 1998 novel
