Hearing testing?

[o_bunny]

I'm about to go shopping for a hearing test, and am wondering what I ought to be asking for.  I intend to call up the doctors that do that sort of thing, and ask detailed questions.

 

I know that many, maybe most, tests simply check response in octaves, and don't test above 8kHz or below 250Hz (I think that's right). I'd like to know the correct names for the sorts of tests that go beyond those ranges and test with finer gradations.

 

I'd also like to know what other specific things I should ask about, and what sorts of things to avoid.

 

FWIW, I'm in Ontario in Canada, so I'm not quite as worried about HMOs and insurance stuff as I would be if I was in the US.

 

(And no, I'm not really worried about my hearing degrading.  Well, I do worry about it, but that's not why I'm looking for the info.  I just want to make sure that I'm still hearing as well as I think I am.)
