Cochlear implant failure
I was progressively hard-of-hear hearing for 25 years or more and by late 2001 was competely deaf. My first cochlear implant to my left ear failed miserably. I realize I was a statistical anomaly, as failure rate is low. The "sound" was nothing like normal hearing I remembered. It was more like a static-filled radio broadcast at high volume in an environment of birds and crickets.
Needless to say, I've gone back to speechreading (it's more than just reading lips) and signing for face-to-face communications.

Under "Deaf Interests," look for the heading, "Hearing Aids & Cochlear Implants." The blurb reads: "Opinions and experiences about hearing aid or cochlear inplant, and how it affects one's life."
