Going back inside audiometric test booth to assess adequacy of hearing aid fitting

Just wondering if there is any benefit to going back into the sound booth after having ones hearing aids programmed with the your latest audiogram to see if you can really hear better what you missed the first time?

Although it appeals a lot to us, it’s not generally done. My understanding is that it’s just not terribly useful.

To expand a bit. My understanding is that the real test to determine if hearing aids will help is the Word recognition score. Even though it’s done without hearing aids, it is done with gain. It is pretty much an upper limit on how much you’re going to “hear” with just amplified hearing alone. However, just because one has a low word recognition score doesn’t mean all is lost in that with the help of hearing aids and taking advantage of all context clues, decent communication is still possible. If one has low word recognition scores and hearing aids don’t seem to help much, people are getting remarkable results with cochlear implants.

The only time it might be deemed useful to retest, is perhaps when you have severe Tinnitus, the Audioligist or dispenser can put a warbled tone whilst testing your loss, in order to distinguish this from your Tinnitus… Cheers Kev :wink:

With cochlear implants this is how the hearing process is judged. We are tested in a sound booth with only the one processor on an ear at a time. Word understanding and then sentence understanding are tested separately. This enables the fitter to see what sounds we are not hearing well, such as certain consonants. Then the processor can be tuned accordingly. A process that could be used with hearing aids too I would think.

Test in booth without aids, for word recognition score, will give you baseline for expectations. This is done with as loud as needed signal.

Then one way of seeing if aids are fitted properly is to go back into the booth with them on, with signal of 65db - and you should get at least the same score as your baseline is.

If it’s lower - aids aren’t set up properly.

But, this has to be done with word recognition test.
Also, can be done with additional noise, that will help to see how to set them up further.

This technique is utilized by fitters who don’t have other tests on disposal (like quicksin), those who don’t have REM based fittings using live speech mapping, but also with those who have all of that but want to be really thorough.

Tonal audiogram is useless with HAs on, since it’s not that we’re interested in our real life in only beeps anyway.

So, there’s more than one test that can be done in the booth. :wink:
