Hi Matias:
  White noise is a mixture of all possible frequencies together evenly,
or equal energy per cycle across the 20-20kHz range of frequencies. A
good example of what this sounds like is the FM tuner off of a station
with the muting off so you can hear the hiss.
 Pink noise, is similarly equal energy across the same range, but it is
equal energy per octave. A much more valuable source for those of us in
audio, allowing us to make meaningful measurements of energy
distribution across the hearable spectrum.
