Dear Nedra, This is an intriguing question, though one not at all easy to address. I guess that the type of illusions you have in mind are those of the type reported by Diana Deutsch and others (e.g., Shepard tones; McGurk effect, etc. ?). You ask how they might be related to hearing-aid design? Do you have in mind trying to reproduce some of these effects in aided hearing-impaired individuals, which they previously could not perceive unaided, as a means of assessing the efficacy of different hearing-aid algorithms? The problem in relating some or all of these illusions to hearing-aid design is that it is quite difficult to dissociate auditory perception, or rather auditory sensory processing, from auditory cognition in these effects: do the illusions arise primarily from the former or the latter? The former might be useful for directing hearing-aid design; I doubt that the latter would though, as the effects might be quite idiosyncratic, relying on such factors as cerebral dominance, linguistic experience, etc., and might make for a moving goalpost, as it were ... You might like to read the following review of Deutsch's two CDs of auditory illusions for more information: http://deutsch.ucsd.edu/pdf/ben_carson_review_AJP.pdf Best wishes in your endeavours, Jose On Aug 1 2011, Bruno Repp wrote: >Dear Nedra: > >Your spell-checker seems to have been under-active as well because it >did not catch the wrong verb form of "tells". > >Your question about auditory illusions was probably intended to be: "Are >there any auditory illusions that have potential relevance to >hearing-aid design?"
