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 fun this sound was -- and is." Julia Leconte of "NOW Magazine" noticed that "at first, [...] Kiesza's debut album seems overwrought [...] but eventually, subtleties and variety emerge" and felt that "Kiesza's so much better when she reels back her impressively ranging vocals to buttery." Chris Chiu of "The Silhouette" wrote that the album "offers the same intensity and sound that made her an instant hit and proved her overwhelming potential," but also that it "suffers from a bit of an identity crisis." Larry Fitzmaurice of Pitchfork Media noted that "Sound of a Woman" "fails to spark, as its
