Sound amplification by stimulated emission of radiation phenomenon, known as the Larsen effect, is the result of a positive feedback. In general, every oscillator consists of three main parts. These are the power source or pump, the amplifier and the positive feedback leading to the output. The corresponding parts in a SASER device are the excitation or pumping mechanism, the active (amplifying) medium, and the feedback leading to acoustic radiation. Pumping can be performed, for instance, with an alternating electric field or with some mechanical vibrations of resonators. The active medium should be a material in which sound amplification can be induced. An example of a feedback
There's a New Sound never "kid themselves properly (or) let their voices go") by making appearances on "The Ernie Kovacs Show" and recording a full-length album, "Music to Suffer By", in the same style she used for "Fish." "There's a New Sound" was later featured often on the Dr. Demento show and performed by Scooter on "The Muppet Show". There's a New Sound "There's a New Sound" was a 1953 novelty song by Tony Burrello and Tom Murray.
