Definitely not. There's the usually tonal hum of the motor, the whine

i like the no load blade whine but could live without

the motor hum is not so loud

the work load is the noise that needs to be eliminated


exist), there would be problems with phase and delay. Your head isn't
stationary. If you're imagining an "anti-noise" generator somewhere
in you're shop it would somehow have to compute the exact signal to
produce that would cancel out the tool sound *where your ears are*,
which is not only a moving target, but *two* moving targets. This is
not to mention the thousands of paths the sound would take as it
reflects off the various surfaces in your shop.

interesting
seems that the best place to create the anti noise is close
to the noise

each noise maker would need an anti noise generator

I find the garden variety 3M ear protectors to be more than
sufficient.

also interesting but not practical
would have to buy multiple sets and disperse to all those in shop
ear shot

then there would be timing issues

maybe i could push out txt msgs to them when i am about to make noise

but what if my wood muse cannot sleep and wants some late night work
or early morn
