I was sitting in an airplane Sunday night, N800 in hand, wishing I had brought along my noise canceling headphones. Then I looked down at my wondrous little IT and thought, "Now THERE would be a great IT app!" Use the built in mic to detect noise than process it to reproduce the same on a negative frequency and they balance out to silence.

Wouldn't something like that be great running in the background behind your favorite audio player? Giving you clean sound without the interruptions of background noise?

Now all we need are some acoustic engineers to write the code. Any takers?!?
