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.
Make a Sound Make a Sound Make a Sound is the only album by American rock band Autopilot Off. In April and May, the group supported Rufio on their headlining US tour. "Make a Sound" was released on April 13 through Island Records and produced by then-Sum 41 producer and manager Greig Nori. The Japanese version of "Make a Sound" includes a bonus track titled "Raise Your Rifles". There is also a limited edition print of the album, that, as well as the Japanese bonus track, includes two additional exclusive songs.
