Our skin, say on forearm can usually feel
vibrations of a speaker when it touches it ; We can
replace earphone part of hearing aid by
flat
speakers which can make good contact with skin. Thus,
to "hear" or feel a sound, deaf person puts the speaker
on any part of his/her body and feels vibrations
instead
of putting earphone in ear; (earphne of a hearing aid is
replaced by a speaker.)
From those vibrations, a deaf person can tell if there is
a
sound
present or not, or how loud it is. This could be better
than
nothing. And this could be used to "hear" morse code.

Cochlear implants tend to work well in cases of profound deafness (i.e. bad enough that conventional hearing aids are ineffective), they are very expensive though. |

Agreed. I think cost is the major advantage here;
plus simplicity of "installation". |

Jo Brand on Van Goch: It was a bit more than that. I mean he was, like, seriously mentally ill, rather than, "not a happy bunny." |
