      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
