Sound amplification by stimulated emission of radiation the axes of the mirrors, it is possible for photons to repeat multiple reflections and force more and more photons to follow them producing an avalanche effect. The number of photons of this coherent laser beam increases and competes the number of photons perished due to losses. The basic necessary condition for the generation of a laser radiation is the population inversion, which can be achieved either by exciting atoms and inducing percussion or by external radiation absorption. A SASER device mimics this procedure using a source-pump to induce a sound beam of phonons. This sound beam propagates not in
A Web of Sound listening to them is humming in a room where another dozen people are humming also, in a constant pitch, never varying, unchanging." Allmusic's Joe Viglione suggested that "A Web of Sound" also influenced such artists as Iggy Pop and The Stooges and Alice Cooper. Stewart Mason, also of Allmusic, remarked that the album blended "the snotty aggression of ["The Seeds"] a bit with some heavier psychedelic flourishes." Writer Malcolm Russell described "A Web of Sound" as being "more adventurous" than the band's debut album, and said it "brimmed with scratchy mid-60s classics." Don Jacobson of "The Beachwood Reporter" called it
