Re: Sound damping in a cubicle

["Gene Kim-Eng" <techwr -at- genek -dot- com>]

Right.  Imagine what the waves are like in that cubicle
after the sound comes out of the servers and bounces
around the place.  It's one thing to read them at a point
relatively near your ears and then emit a cancellation
signal into your ears, but to generate cancellation that
would blanket the entire space and be effective at all
points within that space without earphones?  It would
be a miracle.
