This information goes along with what my friend with the cochlear implant has told me--before his implant he could not detect consonants. Now he can. Carol PS--I feel old. I couldn't hear the ringtones at all.

A quick google confirmed that high frequencies may indeed be important for speech perception and that the selective high frequency loss for aging contributes to the difficulties older folks have understanding spoken speech. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&lis t_uids=10990011&dopt=Abstract http://www.skinandaging.com/cg/displayArticle.cfm?articleID=cgac193 http://www.merck.com/pubs/mmanual_ha/sec3/ch37/ch37b.html Take care Jim James M.

According to Medline, "In detailed audiometry, hearing is normal if tones from 250 Hz through 8000 Hz can be heard at 25 dB or lower." (http://www.nlm.nih.gov/medlineplus/ency/article/003341.htm) > >Your hearing aid may also cut off the highest frequencies. "Sometimes a satisfactory level of hearing can be restored by a hearing aid - a combination of a microphone to sense ambient sound, an amplifier, and a tiny speaker that projects the amplified sound into the ear canal. A typical modern hearing aid would employ an electret condenser microphone - small and rugged with a high signal-to-noise ratio. The frequency range of application is typically 100-10,000 Hz." >(http://hyperphysics.phy-astr.gsu.edu/hbase/sound/hearloss.html#c2) > >-- >Sue Frantz Highline Community College >Psychology Des Moines, WA >206.878.3710 x3404 [EMAIL PROTECTED] >http://flightline.highline.edu/sfrantz/ >-- >Office of Teaching Resources in Psychology Assistant Director for >Project Syllabus http://www.lemoyne.edu/OTRP/projectsyllabus.html > >________________________________ > >From: Annette Taylor, Ph.
