Thanks Cancuckian Chick. Price is something else
I've been looking into it, but seems like my aid is not compatiable with the one I want the most which requires a euro input or something of the sort, or portability becomes an issue(especially since we carry walkers, forms, kits).
To the Topic Creator; I stumbled across this website that's designed for people with hearing loss in the medical field. Granted, the number of posters there are small, but looks very resourceful. It might be a great place to get some basic info. Here's the link:
http://http://www.amphl.org/forums/index.php You can also check out what others say in other fields as well (as it includes fields such as audio, assistants, nurses, therapy, etc..). There's also a mention of the mask & surgery concerns in their forum.
The link provided: (AMPHL)The Association of Medical Professionals With Hearing Losses which is designed for individuals with hearing loss interested in or working in health care fields. Hope that helps.
