Good Explanation of Masking, and Different Types of Noise (Pink, Brown, etc.)

This isn't really Research News, but I can't see a better place for something on-topic like this. Feel free to move, admins.

This is a post on Reddit that explains the different types of noise and how they interact with other sounds.

thanks dezdog interesting link

heres a summary of what i know about sound spectrum and power output for frequency

white noise has equal power output over the entire sound spectrum

pink noise is a sound spectrum with decreasing power output as the frequency goes up

brown is like pink only more so

blue noise has greater power output as frequency increases kinda the opposite of pink noise

and violet noise is like blue noise but more so,,,kinda the opposite of brown noise

i even have heard about something called grey noise...it has a U shaped power output over the sound spectrum (higher power output at higher and lower frequencies and low output in the middle

for me white noise works best for helping me to stop thinking about by tinnitus

best wishes
