There's a bit of work on how the auditory system might have adapted to such filters given the structure of sound. It doesn't have an obvious connection to 1/f spectra, but it comes up with a pretty good reason as to why auditory filters are the way they are. My work is more CS oriented: Lewicki's work has more neuro-credibility, mentions 1/f in passing: Paris
