Sound amplification by stimulated emission of radiation Sound amplification by stimulated emission of radiation Sound amplification by stimulated emission of radiation (SASER) refers to a device that emits acoustic radiation. It focuses sound waves in a way that they can serve as accurate and high-speed carriers of information in many kinds of applications—similar to uses of laser light. Acoustic radiation (sound waves) can be emitted by using the process of sound amplification based on stimulated emission of phonons. Sound (or lattice vibration) can be described by a phonon just as light can be considered as photons, and therefore one can state that SASER is the acoustic analogue
I Changed a Lot of HipHopDX said, ""I Changed A Lot" lacks a “We Taking Over”-style smash single to show for the incredible hit-making power of the performers present. Something just feels off in Khaled's traditional manner of creating ubiquitous pop cultural touchstones.
