Subject: History of cochlear implant slides From: "Ward R. Drennan" <wdrennan(at)MAIL.KHRI.MED.UMICH.EDU> Date: Wed, 24 Mar 2004 11:42:48 -0500I've heard that there's a slide (power point image) from Cochlear Corp. that showed changes in the cochlear implant performance over its history. It shows the improvements in speech recognition over the last 40 years based mostly on improvements in the speech processor design, but also on increases in the number of electrodes used. If I recall correctly avergage word recognition performance improved from 10-15% in the late 70s to 70-80% in the mid 90s for post-lingually deafened adults. This is great progress and the slide shows it well. Does anyone have this slide or know where I could get a copy?
