Re: correction to post

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:


Best wishes in your endeavours,

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?" I'll leave this question to others to answer, as I don't know much about hearing aids.

My apologies for an over-active spell checker that changed "people" to "proletariat" in my recent posting. Below is the message I intended to send:

I'm a science writer/audiologist researching an article on auditory illusions. What value do they have "on the ground" for people with hearing deficits? Do what they tells us about the brain and hearing have application to hearing aid design?

Thank you,
