Dear List, I have heard it said on a number of occasions that 1/f spectra are very commonly encountered among natural signals, and one might perhaps expect the auditory system to reflect this fact in its design (perhaps the fact that auditory filters get wider at higher CF and are approximately logarithmically spaced is a simple relfection of the 1/f nature of many sounds?) However, I don't know ANY literature that discusses this 1/f phenomenon. I seem to remember somebody mentioning at a conference that there is a "classic" Science paper that marks the "discovery of the 1/f phenomenon". If that is the case, I'd love to know the citation for it. Any other references for other (particularly recent!) work relating to 1/f and it's role in audition would of course also be very welcome. (Even better would be pdf files of relevant papers, if anyone has any). Thank you very much in advance for your help, Jan Schnupp Dr. Jan Schnupp University Laboratory of Physiology Parks Road, Oxford OX1 3PT, UK Tel: +44-1865-272513 Fax: +44-1865-272469 E-mail: jan.schnupp(at)physiol.ox.ac.uk
