Here’s a bit of news that we haven’t told anyone: Christopher failed his hearing screening when he was at the hospital. We talked to the pediatrician, who said that the hearing test they give is wrong about 95% of the time when it fails. He suggested that we schedule an appointment with the audiologist for a more advanced test when Christopher is 1 month old.
Well, this morning we had him tested again. The results were good, but not conclusive. The reason is that he breathes pretty loudly, and the instrument they use doesn’t work right unless the baby is quiet. That said, Cindy, the audiologist, was able to determine that his ear was responding to 3 of the 6 frequencies in one ear–there was too much noise to get good data from the other ear or the other frequencies.
Once I asked the electrician why, when something is wrong, they don’t look at the wiring in the wall. He said that 99% of the time the internal wiring is fine, and it’s the connections at the ends that are wrong. It turns out that it’s the same way with ears. 99% of the time, if the physical elements of the ear are working, then a person can hear. In other words, it’s very rare for the ear to be working right, but for something to be wrong in the brain that prevents hearing.
I guess this is good news. So far, we haven’t been able to startle Christopher with sounds. You might remember that he slept through the 4th of July–and the fireworks were practically right above us. I’ve also tried waking him up with an alarm. We asked the audiologist about this, and she said that it’s not uncommon for sleeping babies to keep on sleeping. She said it’s more likely that they would be startled when they are awake.
So, overall, I think we got some good news today. It looks like his ears are working. We’ll go back in a few months to test him again, when hopefully he has learned how to breathe quietly.
