Noise issue and worried about it if i have workshop built any views or help please

[Jester]

A while back while i was working in a the depths of an RFA Vessel. We got to thinking about noise reduction or even noise cancelling. We tried a few methods and was semi successfull use a mike and a laptop output the opposite noise. In a small ish place it could work quite well. The computer would in realtime monitor the noise created and output the opposite noise to cancel it out. If i can find the software i used ill post it up.

I know its slightly ott and probably not worth the time, but for al diyers its a great little project.

The principle is that the software generates a inverted sound, essentially cancelling out the sound around you.
