Refraction, in acoustics, comparable to the refraction of electromagnetic radiation, is the bending of sound propagation trajectories (rays) in inhomogeneous...

This refraction is due to the velocity of light through air decreasing (the refractive index increases) with increased density. Atmospheric refraction near...

During propagation, waves can be reflected, refracted, or attenuated by the medium. The behavior of sound propagation is generally affected by three things:...

increase the audibility of sounds downwind. This downwind refraction effect occurs because there is a wind gradient; the sound is not being carried along...

varying composition of the melon creates a sound velocity gradient that refracts sound directionally. Sounds also bounce off the skull and air sacs that...

the sound of thunder is refracted through the troposphere. This refraction results in spaces through which the thunder does not propagate. The sound of...

underwater acoustics was published, theoretically describing the refraction of sound waves produced by temperature and salinity gradients in the ocean...

such refraction causes multipath propagation and fading. When an inversion layer is present, if a sound or explosion occurs at ground level, the sound wave...

Earth's atmosphere. A sound speed gradient leads to refraction of sound wavefronts in the direction of lower sound speed, causing the sound rays to follow a...

Since the sound waves move from a lower velocity material to a higher one during sound production, the sound undergoes inward refraction and becomes...
