Default Homebuilt active noise control for bedroom

We currently have one of the quietest ceiling fan models in our bedroom,
but
I'm wondering if I can suppress that fan noise even further. However, we
don't want to wear earplugs or noise-cancelling headphones while we sleep.

Just an idea-- Was wondering if it could be possible to somehow make the
sensor and signal processor of one of those noise-canceling headphones
(For
example, Panasonic RP-HC500) drive a larger amplifier, which would in turn
power a pair of small cheap PC type speakers. The little speakers could
then
be spaced apart above the headboard of our bed.

Was hoping that I could obtain all components that I need (except the
RP-HC500 and the PC speakers) at Radio Shack or some other local
electronics
components retailer. However, I'm not an electronics tinkerer so I have no
clue as to what the specs would be for those components.

From school (long ago) I have a vague and very limited knowledge of
electronics (Ohm's law, impedence matching), but know nothing about
amplifiers and next to nothing about filters/tuners.

Don't want to spend more th

an a total of US$400 on this. Is the idea
feasible?


For $400.00 you might think about hiring a girl with a large feather
fan to keep you cool. :-) (ala ancient Egypt)
