Hello

I'm after someone who can make an "Active Noise Cancellation Device".

If you're that someone and would like some extra cash please contact
me at [email protected].

Thanks

Seimens is supposed to have these. The good ones are fairly expensive,
and they are all very limited in performance. Noise is very complex, and
all the situations are very random.

We would not even dare to take on such a project at our company, because
of the wide parameters, and customer satisfaction factor.

Wouldn't it be cheaper to buy a pair of off-the-shelf noise canceling
headphones?

I heard it's next to impossible to get it to work well anywhere other than
in a headphone set up. Even then I heard there are problem if the acoustics
of the headphones aren't just right.

I had such high hopes when I saw ANC demonstrated with a wood chipper
several years ago. I thought this technology was "right around the corner."

My fondest dream -- I want one inside my PC case. The fan noise is making
me crazy, hour-after-hour, day-after-day.

To solve that 'problem' you don't need ANC.
Buy yourself a remote KVM unit and put your PC in a place where
you cannot hear it.

Replace the fan. There are some which can vary the speed by temperature. And
watch for the fan on the processor (if you have one). Some of those can
sound like a locomotive wreck.

Power consumption, the associated heat, and hence the associated fan
noise are three aspects of the same problem which is the bane of PCs.

I've switched much of my computing to Sun Rays to cope.

It's an advertisement, can't you see?! It's a spam!
It's a trick with this noise cancellation...

Hmmmm, check out the Fenton Silencer, you'll find it in Arthur C. Clark's
"Tales From The White Hart"
Ol' Fenton still had some glitches in it, but the story dates back to the
forties!

Try the Bose noise-cancellation headphones. They are fantastic. I
tried them on a USA to Frankfurt flight a couple of years ago, and
there was absolutely no plane noise when they were turned on, only the
music I was listening to. If you turned the music volume all the way
down, there was amazing silence until you took the headphones off.
Expensive, but an engineering marvel.
