My house is noisier than yours. I know this because I think OSHA would require hearing protection in this place.
Our house it has a crowd
There’s always something happening
And it’s usually quite loud

I have some wonderful noise canceling headphones but they don’t completely isolate me from the noise. That is, until I decided to pump some white noise through them! http://simplynoise.com/ has some downloadable white noise clips. You can down 30 seconds of white, pink and brown noise that you play in a continuous loop. You can also download a one hour thunderstorm! This works so well I thought I was home alone!
