Sound amplification by stimulated emission of radiation of a coherent amplification of THz sound. The THz stimulated phonon induced transitions between the electron superlattice states lead to this coherent amplification while processing a population inversion. An essential step towards coherent generation ("sasing") of THz sound and other active hypersound devices has been provided by this achievement of THz sound amplification. Generally, in a device where the threshold for "sasing" is achieved, the technique described by this proposed scheme could be used to measure the coherence time of the emitted hypersound. Sound amplification by stimulated emission of radiation Sound amplification by stimulated emission of radiation (SASER) refers to

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
