system and fluid buildup.
And when these children walk around with fluid in the ear or negative pressure because of your station tube dysfunction, they don't hear clearly.
You know, if you have a 20 to 40 decibel loss of hearing, you don't hear clearly.
So that's number one.
We have to be sure that hearing is normal.
And if hearing is normal, it doesn't mean they perceive
Speech as well.
I mean, they have normal hearing acuity for pure tones that we test.
But when it comes to speech and the clarity of speech or the figure ground skill, the ability to listen in background noise or competing conditions, that becomes deteriorated.
And that's where we start to see the perceptual difficulty, the hearing imperception, which is what is a hallmark of auditory processing disorder.
the inability to hear the clarity or be able to listen in competing conditions.
So we do tests, and we provide difficult listening conditions.
And one of the reasons we make it difficult is that we try to bring forth upper auditory pathways.
We make it more difficult, and therefore we're taxing upper pathways that lead to the auditory cortex.
So a child will hear words that are coming in
in each year different words in each year at the same time that's called dichotic listening
We can do sentences in each ear at the same time, but now the child has to listen to only one ear and not pay attention to the other ear, and that's a binaural summation effect.
It means the upper auditory pathways are being stimulated, and we need to now see how they integrate, how one could suppress the other pathway.
We also give the youngster words that are muffled, and we ask the youngster to figure out what the word is that's a closure skill.
And we use internal resources in order to do that.
