He added: "The course was great, the acoustic theory
in the first year opened my mind to the way hearing works, and the synthesis and electro acoustic composition modules were a good basis for electronic creativity.
I don't think you'll find many archaeologists who know about Stonehenge giving this particular acoustic theory
a lot of time," he added.
Henderson developed a hypothesis that one solution could be the designing of "filters" into the piping systems based on acoustic theory
Within the past several decades, however, a revolution of method and understanding has taken place in this field, embodied particularly in four books: Andrew Barker's two volumes of translations with extensive commentary, Greek Musical Writings I: The Musician and His Art (Cambridge: Cambridge University Press, 1984) and Greek Musical Writings II: Harmonic and Acoustic Theory
(Cambridge: Cambridge University Press, 1989); Martin L.
Vibration Technologies, headquartered in Shreveport, Louisiana, has developed proprietary equipment which utilizes acoustic theory
to transmit standing wave resonant energy over long intervals of pipe in oil and gas wells.
