Explaining Sound To A Deaf Person from Joana Pimentel on Vimeo.
Incoherent vid and who is it aimed at? Can't be hearing to raise awareness, can it? Would born deaf be interested at all? Next video, explaining to hearing what sign is all about (Again not using captions or narrative). I'm sure they will get that too. You can understand an audio description helps a blind person but its not the same with deaf people, we have numerous alternatives to sign.
