Brain Hearing

We actually hear in our brains, not in our ears. Wow. Who knew? I often remind my patients about the well known phenomenon of moving next to a railway track. At first the noise of the train drives most people “around the bend!” But after a few weeks most people do not even notice it. The ears are still picking up the sound but the ever-so-smart brain says “eh, not important…don’t notice it anymore.”

People with normal hearing process sound in the auditory cortex, at the sides of the brain. However, brain scans show that people with hearing loss process most sound in the frontal lobes. I think it’s very cool that other parts of the brain can take over. Unfortunately, the frontal lobe is where working memory is performed. This means that during a conversation, a hearing impaired person cannot just sit back and listen to the conversation. They are actively using their working memory to figure out what is being said. This takes a lot of focus and energy.

Many of my patients tell me that when they are experiencing difficulty
hearing, they are often told to “turn up their hearing aids.” Let me try
to explain why this is not helpful.

 
First, a bit of anatomy. Some people have a conductive loss which means
sound is blocked from entering their ears properly. The blockage is in
their ear canal, at the eardrum or in the middle ear space where the tiny
little bones vibrate. For them, turning up their hearing aids is often a
good option.

 
Unfortunately, the vast majority of people with hearing loss have a
sensorineural hearing loss which means they have damage in the inner ear
or auditory nerve. Inside the inner ear (cochlea) there are tiny little
haircells which are actually nerve cells. Once the haircells are damaged
there is no way to repair or restore them. Those nerve impulses are lost
forever. This damage in the cochlea distorts sound. So for many hearing
impaired people it sounds like everyone else is mumbling. Even worse,
people can sound like “Daffy Duck.” If you sound like Daffy Duck to your
significant other, a louder Daffy Duck is not going to help!
