It can be very frustrating to find a good audiologist. I looked a long time to see if I could find a list of what a "best practice" audigram would cover.
As far as I know, neither of the two professional organizations for audis has it on their web sites. (
American Academy of Audiology ,
American Speech-Language-Hearing Association | ASHA)
But I did find one here:
Demystifying Hearing Testing
Before you agree to take an audiogram, see if the audiologist will include all of the tests listed in the above article.
As far as the bone conduction test goes, at any frequency where you're hearing loss is greater than 60 dBs, the bone conduction test "doesn't work". That's because any sound at 60 dB or higher through ear inserts will vibrate your skull, so of course you will "hear" it. (40 dB is the limit of usefullness of that test when given with headphones).
Other than that, a basic audiogram should include all of those tests -- but AFAIK, not all audis give them. This can be one way to screen audiologists -- they're response to that article.
Other than that -- word of mouth is a good way to go. Do you know anyone nearby who has a similar hearing loss to yours? Do they appear to be able to hear well (or as well as can be expected) in many listening situations?
And it probably is a good idea to see if the recommended audi is a member of the American Acadmey of Audiology and American Speech Language Hearing Association.
Make sure that they carry brands that can be fitted to profound/servere losses. If you are interested in
BI-CROS hearing aids since you are deaf on one side, ask them if they carry those type of hearing aids and have experience in fitting them.
Good luck!
