Pink noise refs?
I am doing an study using naturally-occurring sounds, and one issue is the
best masker to use. Up until now, we have been using white noise, but now
we are wondering whether a pink noise masker would have more 'ecological
validity' (for those of you who can stomach that term). I would be
grateful for a references to comparisons of white noise and pink noise
maskers for any type of signal, and to any studies which might indicate
whether background noise is indeed 'pinkish' or not.
