Grindstone (Canada) Portable Negative Noise Generator I'm trying to find out if anyone has invented a portable negative noise generator for in the house. I'd love a small, portable machine that analyzes a noise source and then puts out a negative wave to counter it. We could put them on/in fridges and washing machines and other noisy items in the home to get those annoying sounds out of our lives.
