So, in what way does it produce an affect with sound?
Does it:
Amplify sound?
Distort/Alter sound?
Diminish sound?
Catch the subject's attention supernaturally?
Attract people?
Invoke a change in consciousness?
Require a certain catchphrase?
Invoke control, or some other conditioned response that would have the same effect on ALL people affected by it?
“…Judge not what a man has done, but judge what he could have done if he was a different bloke altogether. For art thou a leper? And a leper can changeth his spots…” --Rudy Wade, Misfits (Series 4, Episode 8)
