Otoacoustic emissions, we do tympanometry, we do acoustic reflexes.
So those are objective measures of how intact the mangue is and the auditory nerve.
Beyond that, there are audiologists that will do EEGs, electroencephalograms, or do ABRs, auditory brainstem tests.
response is to see the integrity of the auditory nerve.
Often if there is a problem in processing, it could be related to an eighth nerve, which is your auditory nerve difficulty or dyssynchrony between the nerves of both ears.
So we look at the function of the auditory nerve, the eighth nerve, and that's accomplished through ABR testing, auditory brainstem response testing, and or
what we call middle and late frequency, middle and late amplitude testing, to see how the youngster will respond.
And this is objective measures because we do it by placing electrodes on various parts of the brain and the ear tip so that we can measure responses to clicks, which is speech, without the child's behavioral response.
There has been incidences where
a youngster may come in and act in a way or behaviorally to affect the results of the testing.
So there are many audiologists that would enjoy using electrophysical measures which are more objective.
So a battery can vary and we don't have any
true gold standard for any SEC battery, but there are a number of very fine tests out there that are standardized, that are non-reference tests, that give us a great deal of information.
And many times we test youngsters against their same age peers.
So if I have an eight-year-old, I know what eight-year-olds should be doing on these tasks, and I measure this particular child's performance against his same age peers.
And I derive information as to whether or not that dumpster is performing the same or less than or as good as.
And that tells me a good deal of information.
Well, I think, and I'm very glad you asked that, Debbie, because
We don't have any data to refute the myth that these children can't be tested before the age of eight or seven.
It was at one point believed to be the case because we didn't have the instruments or the tests that would norm down to those levels, but now we do.
