Profoundly Deaf and Can Use the Phone Easily?

Now, this sounds like a big fish story but I was in a board discussion with one hearing mother who claimed that her profoundly deaf son, who is an adult and already college bound, wears his hearing aid and can have conversations over the phone easily. I asked for a few more details asking the dB loss, type of hearing loss (ie sensorineural, meniere, etc..) and the kind of conversation that takes place. I'm still waiting for that answer. I even offered to give him (through his mother) my email address so we can exchange cell phone numbers.

Now, I don't know what the mother's definition of what constitutes a normal phone coversation but it certainly does not entail repeating everything constantly or even loudly. Or even avoiding conversations with other strangers over the phone whose voices are not familiar to begin with. But color me skeptical on believing a person with profound hearing loss who wears a hearing aid can have normal conversations over the phone. Certainly those with moderate to severe hearing loss have a better chance on having normal phone conversations while wearing a hearing aid than those who have profound hearing loss. If one can converse normally over the phone also means he/she has a high word discrimination ability and that would generally be into the 90s percentile range.

Does anybody who knows someone who is profoundly deaf, wears a HA, coverses easily over the phone and understands clearly the other person's voice?

Anyone?

And if so, send him or her my way and I'll call that person up myself.
