Normalizing white noise to match pink noise's amplitude at a given frequency?

Normalizing white noise to match pink noise's amplitude at a given frequency?
  1. What is the frequency range of pink noise?
  2. Is pink noise equal energy per frequency?
  3. What is the difference between pink noise and white noise?

What is the frequency range of pink noise?

Pink noise is similar to white noise in that it is also a broadband noise, containing all frequencies between 20 Hz and 20,000 Hz. However, pink noise is deeper than white noise due to a reduction in power at higher frequencies and an increase in power at lower frequencies.

Is pink noise equal energy per frequency?

In pink noise, there is equal energy per octave of frequency. The energy of pink noise at each frequency level, however, falls off at roughly 1-3 dB per octave. This is in contrast to White noise which has equal energy at all frequency levels.

What is the difference between pink noise and white noise?

Pink noise is white noise, but with reduced higher frequencies. It resembles the sounds of steady rainfall or wind and is often considered to be more soothing than white noise, which some people find unpleasant.
