I’m wondering if someone can explain to me how one would determine the accuracy of a speech discrimination test? From what I’ve experienced, it seems the person performing the test subjectively determined if I repeated the word/sentence back to them correctly, and then recorded my overall score. Is the testing, in fact, subjective? I.e., if the person performing the hearing test yawned, sneezed, or misheard my response, could they then record that I misheard the word, when it fact it was them who misheard my response?
The reason I ask is because, as some of you know, I had four hearing tests done last year prior to getting my hearing aid. The first three tests were done by people who I presume had “normal” hearing. (I say I presume they had “normal” hearing because none of them appeared to be wearing hearing aids, but I’m fully aware that any of them could potentially have been HOH.) I scored 100% in each ear on all three tests. The fourth test, which was performed by my current audiologist, who has a moderate-to-severe hearing loss bilaterally and wears hearing aids, scored me at 94% for one ear and 96% for my other. At the time, I thought it was strange that my speech discrimination had gone down that much in the space of two months, but I just assumed that was life and I’d better get on with it. Then this spring I had an appointment with an otologist who again had my hearing tested. I scored 100% in both ears at that time. So…why the dip in the fourth hearing test I had? Is it possible that my audiologist misheard me?
I know some of the audiologists and hearing instrument specialists on this forum are hearing aid users. For those of you who are, how do you know that you’re accurately hearing what a client is repeating? Please don’t take this question offensively. I’m in no way suggesting HOH people should not become audiologists or HIS. (I’m contemplating taking the HIS program myself because I’m truly finding hearing loss issues fascinating!) I’m merely asking how people who have a hearing loss, even one that is aided, are able to determine someone else’s speech discrimination? Thank you, in advance, for clarifying!
