    Default Interpreting Real Ear Measurment Terms

    On my Costco REM results, there is a graph that includes two threshold curves. One is UCL, which I'm confident is Upper Comfort Limit. The other is THR, which I think is Threshold. It's shape is very similar to my audiogram, but the numbers are a bit higher. From research, it looks like this is kind of a conversion of the audiogram using REDD (real ear to dial difference) My understanding is that REM levels that are slightly below THR might suggest an increase in gain. However ones that are way below THR suggest it's pretty much a lost cause. I know that this is necessary for me to use my hearing aids, but I find it interesting. Any comments that suggest my understanding is ballpark or point me in another direction appreciated.

    I sure don't know the answer, but maybe this page might help...

    Corona,
    Thanks! That was one of the articles (and a very good one!) that I used to help me think I've sort of got this. Mark

    Yay! I've got to set my audiology-learning aside for a bit, and write a thesis. It's sure interesting, though!

    Good luck! The forums can be a tremendous distraction.

    THR is your hearing result in dB (SPL) as opposed to dB (HL). This is shown so that it can be compared with the dB (SPL) output of your hearing device into your ear cavity. You can't express the output of the aid as a function of your loss dB (HL), so the figures are converted into the equivalent level dB (SPL).

    I know it sounds weird, but it makes sense, simply in terms of having a positive output figure for the aid vs a positive target, which you couldn't express against the your hearing level which 'has' to be a negative number.

    Thanks it makes sense. It also provides a dramatic graphic of the futility of trying to generate enough gain to "fix" a profound ski slope loss.
