Guest guest Posted May 24, 2006 Report Share Posted May 24, 2006 OAE = oto-acoustic emissions. When you send sound into the ear. The cochlea responds to the noise (and creates its own sound) and hair cells vibrate, which stimulate auditory nerves which pass the signal to the brain and it is processed. When the sound is presented into the ear and the cochlea does not respond in any way - because there are no hair cells or because part of the cochlea is damaged, The output sent back into the OAE machine is measured. This is how they can determine a SNHL from the OAE.

Our audiologist explained it this way: Sound is created by sound waves moving through the air. When sound waves enter the ear, they move into the inner ear and stimulate the hair cells (which then stimulate the nerve endings to tell the brain that sound is present). When the hair cells are stimulated, they move in response. That movement triggers sound waves of their own, which move *out* of the ear. The OAE is designed to pick up the sound generated by this action, compare it to " normal " benchmarks, and determine if the response sounds are within normal parameters. 's loss was confirmed to be SNL in nature by this test. No causes of a conductive loss were readily apparent, so we did the OAE. His right ear charted exactly as expected (I got to be there and see it as it happened - it was tracked on a laptop computer in the lab). His left ear had no response whatsoever - a complete flatline. This also played a large role in 's diagnosis of a complete loss in his left ear. I hope this helps!

Last week, I had my annual audiogram to track my very mild hearing loss (which has remained unchanged for the last 3 years - yeah!). This time they did an OAE test on me, which they never have done. Guess what? I have absent OAE's Bilaterally. So, what does that mean? I honestly haven't a clue and would have thought as you wrote. I mentioned it to my Neurologist and he didn't have a clue either. I would have asked the audiologist who did the test but she didn't mention it to me and was rushing to get through the tests so she could attend the squadron picnic - which I will have a chat with someone about. This Saturday, as chance would have it, my son graduates High School (which is a whole celebration by itself) and a good friend has asked to sit with us, and he happens to have his Ph.D. in Audiology, so I'll have a chance to chat with him and get some answers, which I'll pass along to you all. Sorry if all I've done is confused the matters. -Kay Kay kay@... The Listen-Up Web http://www.listen-up.org Quote Link to comment Share on other sites More sharing options...
Guest guest Posted May 25, 2006 Report Share Posted May 25, 2006 Thank you Kay, I would really like to hear the answer to this. Bree had her infamous ENT appt yesterday that we waited for a month to get and they said " because her OAE was 'passed' that she is fine there is no HL " . Still trying to better understand how the OAE can tell them that. She did terrible in the sound booth I have no clue how the lady got the results she got- couldn't condition her for nothing, tried sound field all she did was " where'd that dog go? " and waited for the dog to clap symbols not look up when she heard the sound. And then in the sound field testing she only did sounds from the right side of Bree only ONE from the left side. Granted a sound field is not as accurate for Right vs Left but STILL wouldn't you do both sides?!?! I don't understand how they think that ONE person can conduct a hearing test in a booth on a 3yro child. The first 2 hearing tests we had done at a different place had an audi doing the controls sometimes with a student and a student or another audi in the booth conditioning her. Even that was hard in the beginning but in the end she's just say " I hear-d it " and not have to drop blocks in the bucket. This ENT we went to yesterday had some boring foam blocks that totally suck they didn't keep her attention at all! Thanks for letting me vent.

Guest guest Posted May 27, 2006 Report Share Posted May 27, 2006 Robin, I'm only a parent that has learned a lot along the way, so keep this in mind. My understanding is if the OAE's are absent then the loss is considered to be a SNHL. But if you have the OAE's then you could have a conductive loss or it may be Auditory Neuropathy (need further testing to determine this). Of couse you could have absent OAE's in only one ear. I'm surprised that they did try to do the testing with just one individual doing the testing. Our first hearing test was done with just one audi and sat on my lap and watched for moving animals. did surprisingly well. She was 2 1/2 at the time, so that may have made a difference. I also remember sounds coming out of both sides of the booth. Our next test a month later was done with two audi's and we got the same results. We've floated between one or two audi's at our tests, but for whatever reason my normaly bouncy child sits fairly well for these tests. Now I will tell you that didn't always " finish " the complete test eveytime. So it got to the point that they would do tone testing at one session and voice testing at another. Do these audi's usually test young children? That can make a HUGE difference in the outcome. If you are not confident in the tests results than schedule another test and request the two audi's be present.
