Sounds you don't want on your noise generator

We sleep with a noise generator... you know, one of those things you pick up at the Sharper Image. It comes with various soothing sounds, like "babbling brook" and "ocean waves."

Here are some sounds you would not want to find on your noise generator:

1. Burly construction workers drilling your foundation walls
2. Needy cats meowing
3. Flatulence
4. running toilet
