Subject: Re: Recent progress in profile analysis? From: Peter Meijer <peter.b.l.meijer(at)PHILIPS.COM> Date: Tue, 16 Nov 1999 14:42:26 +0100Dear All, Many thanks to all who responded privately to my query=20 about recent publications on auditory profile analysis! Below you will find a summary of replies, including the=20 Heinz and Formby reference that I had given as an example: H. Gockel and H. Colonius, ``Auditory profile analysis: Is there perceptual constancy for spectral shape for stimuli roved in frequency?'' J. Acoust. Soc. Am. (JASA), vol. 102, pp. 2311-2315, 19= 97. H. Gockel, ``On possible cues in profile analysis: Identification of= =20 the incremented component,'' J. Acoust. Soc. Am. (JASA), vol. 103, p= p. 542-552, 1998. M. G. Heinz and C. Formby, ``Detection of time- and bandlimited increments and decrements in a random-level noise,'' J. Acoust. Soc.= Am. (JASA), vol. 106, pp. 313-326, July 1999. N. I. Hill and P. J. Bailey, ``Profile analysis with an asynchronous= target: Evidence for auditory grouping,'' J. Acoust. Soc. Am. (JASA)= , vol. 102, pp. 477-481, 1997. J. J. Lentz and V. M. Richards, ``Sensitivity to changes in overall = level and spectral shape: An evaluation of a channel model,'' J. Acoust. Soc. Am. (JASA), vol. 101, pp. 3625-3635, 1997. J. J. Lentz and V. M. Richards, ``The effects of amplitude perturbat= ion and increasing numbers of components in profile analysis,'' J. Acous= t. Soc. Am. (JASA), vol. 103, pp. 535-541, 1998. plus two references for which I have not yet looked up the details: Neff and Dethlefs, JASA, vol. 98, pp. 124-134, 1995. Neff and Jesteadt, JASA, vol. 100, pp. 2289-2298, 1996. Earlier publications can be traced through these references. The reason for my continued interest in auditory profile=20 analysis and auditory grouping/segregation is of course the unanswered question to what extent visual information may be presented to blind people via the kind of auditory display as originally proposed in the IEEE Trans. Biom. Eng., vol. 39, pp. 112-121, Feb 1992. In other words, issues like What are the basic perceptual limits and what are the=20 limits to human auditory pattern recognition and the=20 human ability to learn and interpret visual information through a cross-modal image to sound mapping.=20 Those with a playful mind can try the latest experimental "Internet sonification browser" extension as described at http://ourworld.compuserve.com/homepages/Peter_Meijer/eyebrows.htm and informally try their own auditory profile analysis=20 capabilities on sounds synthesized from on-line images.=20 (No screen reader is needed for sighted users.) Clearly,=20 this line of work is a major gamble, going well beyond=20 what is solidly established from a scientific viewpoint.=20 Ideally, I think we can end up with a "meet-in-the-middle"=20 situation for certain parameterized classes of images that correspond closely to the spectrographic data sets like=20 those studied in the above references. Lots of things to explore... Best wishes, Peter Meijer Soundscapes from The vOICe - Seeing with your Ears! http://ourworld.compuserve.com/homepages/Peter_Meijer/winvoice.htm =
