I wrote a couple line bash script wrapper around a brown noise generator using sox + coreaudio. It works well for me, especially with overhear headphones.

Before that I used SimplyNoise (https://simplynoise.com) which is good, but still uses Flash and so is resource hungry if you're running on battery.

I also work from my home office as much as possible which has a very consistent AC fan that blocks most outside noise.

Wow, that is awesome! Using it now. Thanks a lot.
