Sound amplification by stimulated emission of radiation mechanism and an active medium. The pumping procedure can be induced for example by an alternating electric field or with some mechanical vibrations of resonators, followed by acoustic amplification in the active medium. The fact that a SASER operates on principles remarkably similar to a laser, can lead to an easier way of understanding the relevant operation circumstances. Instead of a feedback-built potent wave of electromagnetic radiation, a SASER delivers a potent sound wave. Some methods for sound amplification of GHz-THz have been proposed so far. Some have been explored only theoretically and others have been explored in non-coherent experiments.
Sound of a Woman Sound of a Woman Sound of a Woman is the major label debut studio album by Canadian recording artist Kiesza. It is her second album after her 2008 self-titled independent release and her first full-length international debut. It was released on 17 October 2014. In February 2014 Kiesza released the video for her new single "Hideaway" through the indie label "Lokal Legend". "Idolator" considered it unique, for having a single take through the entire video, as Kiesza walked and danced through the streets of Brooklyn. John Gentile of "Rolling Stone" called the style "impressive". Kiesza reported to "Rolling Stone" that
