The first test she did was a tympanometry test. This is where she inserted an ear probe into his ears individually. This test tells the audiologist how well the eardrum and the other structures in the middle ear are working. The ear canal volume tests whether there is fluid in the ears or whether there is obstruction in the ears. The first attempt in both ears showed no reading which she thought was strange. She changed the probe size to a smaller size and the reading was perfect. She advised that Jason obviously has very small ear canals and the probe was probably sitting against the cartilage of the ear instead of in the canal. By changing to the smaller size the reading was perfect. This test tests the mobility of the eardrum and detects fluid in the ears.
The second test she did was an audiometer test where Jason wore headphones over his ears and had to listen to a sound and when he hears the sound he must clap. The audiologist explained to Jason how the test worked and he didn't understand the concept of the test and didn't clap when needed. This was more an understanding thing rather than a hearing thing.
The third test done was an acoustic reflex test. This test measures the contractions of the stapedius muscle which is important as it protects the ear from loud noises. The test measures the loudness levels or the absence of the acoustic reflex.
Jason therefore hears fine and there is no fluid in his ears. To me this indicates that he hears fine but his response to hearing is more and understanding thing rather than a hearing problem. I guess a bit of "selective hearing" as well.
Mommy is very happy that all is well.
