Hmmm ... I'd raise a couple of points with that. The first is: when is a
bell rung? Is it rung when it is struck or when you hear the sound? And
related to that, I CAN actually un-ring it. Because the sound takes a
finite amount of time to travel, I can sense it between you and the source
and generate an opposite signal that cancels it out before you hear it.
There are a lot of technologies that use that method for sound deadening.
And please note that I said Method not Methodology.
Happy Christmas eve to all.
