Audiologists test a patient’s un-aided hearing to get a frequency curve, word recognition score, speech in noise score, etc. in order to see where they deviate from normal. Then they fit and program hearing aids to try to get hearing as close to normal as possible, within the limitations of the aid’s capability and the degree of the patient’s hearing loss.
It seems to me that a good way to check how much the aids are helping is to do another hearing test with the programmed aids in. Then compare the frequency curves etc. to see how close to normal the hearing aids get the patient’s hearing. Maybe do this in addition to REM.
But in all my years of reading about hearing aids, watching Dr. Cliff and Matthew Allsop on youtube, as well as other youtube Audi’s, I have never heard anyone suggest this. So it must not be a valid means of verification. Anyone know why it’s not done? Has your hearing care professional ever done this?
