The Truth About Hearing Aids

Many people have the misconception that hearing aids correct hearing the same way that glasses correct vision. This is a far, far cry from the truth. In reality hearing aids simply aid the wearer in hearing better. The key word is better.

Since hearing loss is very rarely, if ever, a straight line a hearing aid needs to amplify a high sound differently than it amplifies a low sound. Being a mechanical device it does this with varying degrees of success. The sound itself is mechanical. Though having never had “perfect” hearing I couldn’t quite tell you how different a hearing aid sound is from the actual sound.

To get an idea of how a hearing aid works think of an old VHS tape that is losing its quality. The sound is fading and in order to hear the volume needs to be turned up rather high. The higher the sound goes the more feedback and other noise becomes involved. Eventually you get to a point where understanding is virtually impossible. This is the same as a hearing aid. The worse the hearing loss is the louder the hearing aid needs to be. The louder the hearing aid is the worse the sound quality and understanding ability is decreased.

My right ear is to the point that even with my hearing aid on I don’t have good voice recognition. If someone speaks only to my right ear I will have trouble understanding what is being said. The hearing aid does help me, but it’s helping my left to understand more than it is able to understand itself.

Hearing aids also do not know what sounds I am trying to listen to. I can’t tell my hearing aid to ignore a loud person behind me so that I can hear a soft-spoken person in front of me, it doesn’t have that capability. I always find crowded places difficult. Going to a restaurant with more than one person invariably has me sitting and guessing at the conversation from time to time. There is just too much noise competition.

Likewise I’m not a fan of background music, or a TV on in the room while a conversation takes place. Anything that fights for my ears attention means communication is not going to be easy.

Very few people seem to understand the reality of having hearing aids. Unless people know me well they don’t take into consideration my hearing struggles. It’s not something that is well known. People assume that hearing aids “fix” hearing. All I have is a volume control on a lousy set of speakers.
The next time you interact with someone who has a hearing loss take the time to make sure they can understand. Don’t talk overly loud or slowly, just be aware of your surroundings. More than likely the person you are talking with will appreciate your effort.

The Accident

A year after my surgery I had just started the third grade. This particular day would change the hearing in my right ear forever.

I was running around with friends at recess. For some reason I stopped short and turned my head. Another girl was right behind me and as I turned her nose pushed into my ear. Her nose ended up pushing my hearing aid into my ear and caused it to bleed. My best friend grabbed the recess aide and brought me to the nurses office. The nurse worked on my ear and called my mom to let her know I had an accident but would be ok. My mom called my primary doctor to get my ear checked, just in case.

A little while later the nurse told me my ear had stopped bleeding and sent me back to class. As I was walking down the hall I noticed little red droplets landing by my side: my ear was bleeding again. Since I was a little goody-two-shoes I tilted my head to keep the blood in, went back to class, and asked for permission to go back to the nurses office. Once there my mother was called again and came to school to pick me up.

When she arrived she looked in my ear and saw skin sticking out of my canal. The injury was bad enough to scrap the skin. She cancelled the doctor’s appointment and took me straight to the Massachusetts Eye and Ear Infirmary to be evaluated.

For whatever reason they didn’t do a hearing test at this time. I wasn’t allowed to use my hearing aid for a while and probably had some sort of ointment to put in my ear, I honestly don’t remember. A few months after the accident I finally had my hearing tested. At this time they discovered that my hearing had gotten worse.

Throughout my entire childhood these were the terms I knew: better, worse, mild, moderate. I was given no sophisticated language to understand my hearing, I couldn’t tell you what my audiogram meant. When I was 21 I did research and gathered all my hearing tests. It was only then that I realized how much my hearing was affected by this accident.

Following the accident my hearing was tested every 6 months but it essentially stayed the same. I was born with mild/moderate hearing in my right ear, just 10 decibels lower than my left. After the accident I had moderate/profound hearing loss. The ranges that hold most sounds only lowered by a few decibels. However the highest sounds, which my right ear could hear better than my left ear at birth, plummeted to 90 decibels. This number, 90, is the “magic” number that indicates deafness. Those high sounds I could no longer hear. To be honest I am talking about 8,000 hertz, which is probably a noise that only dogs can hear. But there has to be something more to it. To this day my right ear becomes excited at the thought of a high sound. It remembers it, cause it surely is not hearing it!

After the accident my right ear was now a good 20-30 decibels lower than my left ear. Did this make a difference to me? No. I don’t remember noticing my hearing changing. I don’t remember having trouble with my right ear. I don’t remember this affecting me at all, sans more frequent trips to the ENT doctor. I assume that my hearing aid was adjusted to accommodate the decrease in hearing. And I went back to listening with my left ear as I had always done.

The day I finally realized what my hearing was and what my hearing became baffled me. I had no clue the changes that took place, I had no clue it was that severe. To me it is not negative but positive. Without this change I would not understand hearing loss the way I do. The difference between my left ear and my right ear have allowed me, in my adult years, to analyze what I hear and don’t hear. With the hearing I was born with I would not have been able to do this analyzing.

I am convinced that this surgery weakened my ear. I’ve had two incidences in recent years, after I was 21 and researched my hearing. Two blows to the head (due to fainting) that has caused even more hearing loss in my right ear. My left ear continues to stay the same, never faltering. My right ear has now passed the 90 decibel mark and is now down to 110 in the 8,000 hertz range. Now I have a 90 decibel loss in more than just one hertz range.

But don’t feel bad for my right ear, it’s special in it’s own right. I have two earrings in my right ear, poor lefty only has one. When I was 19 I felt my right ear needed something special. I often tease that righty is just for show. Today my voice discrepancy is failing in my right ear. When I first found out about the 110 decibel loss I asked my husband to whisper in my right ear. I heard a tickling popping sound. He was saying testing 1, 2, 3. I’ve learned to no longer listen with my right ear. When I was young I focused on my left ear but knew my right could comprehend as well. Now if a sound is solely geared towards my right ear I usually am not able to follow what is being said.

In righty’s standing defense to all of this, as I type, she has been yelling at me, in her high pitched, numbing, tintinitus way. Yes, dear righty, I know you are special, that is why I am writing about you. But could we please stop the tantrum and put the ringing to rest? Her answer is a higher pitch. If only my 110 decibel loss could help me against the sounds coming from my own head.

Surgery

When I was eight years old I had surgery on my right ear. The most I remember of the planning stages was the doctor asking me if I wanted to only wear one hearing aid after surgery. I got all excited that I wouldn’t have to wear my left hearing aid anymore. However this was not the case. Even though I didn’t fully understand the reason why the hearing aid they were hoping to remove was my right one.

I was born with better hearing in my left ear. This is something I have always known. I listen with my left ear, use the phone with my left ear, and turn my left ear towards a sound I am having trouble hearing. It’s instinctual, natural, a part of me. However it was my right ear that qualified for surgery. To this day the idea of my right ear hearing better is a very strange one for me.

My left ear has primarily nerve damage to it, which to the best of my knowledge is not something that can be operated on. My right ear has primarily bone damage. It was this bone damage, in the middle ear, that the doctor’s hoped to improve my hearing by fixing.

The day of the surgery I remember being in a crowded children’s room, reading a book while I was prepped for surgery. I had to have some medicine put into my rear end that I did not find very enjoyable. When it was time for surgery I wasn’t wheeled down to the room. In exchange I was given a piggy back while I held onto my two stuffed animals that accompanied me on the trip: Chip and Dale. In the operating room I watched my heart rate on the monitor before drifting off to sleep.

The surgery consisted of removing the two smallest bones in the body, the Incus and Malleus, from my head. The Malleus was reshaped and put back in, the Incus I was given in an old eye drop container filled with liquid. This was supposed to help my hearing. In order for my ear to heal properly I had to limit my physical activity for 8 weeks after surgery. Keep in mind that I was eight years old and this was August.


(1=Malleus, 2=Incus)

After the surgery my mother waited for me to wake up in recovery. She saw other people wake up very slowly and groggily. Not me, I woke up and sat straight up with a fast movement, something I wasn’t supposed to do! After being brought to my room for the night I was told that I could eat in an hour if I hadn’t thrown up. An hour passed and my mother left to get the nurse to get me some food. As soon as she left I threw up. My father called the nurses station for assistance.

The next hour passed and I was doing well. My mother left once again to get me some food. Once again I threw up before she could return and my father had to call the nurses station. This continued all afternoon. Finally at nighttime the nurses felt sorry for me and gave me a Popsicle. I remember thoroughly enjoying it.

After one night in the hospital, with my mother by my side and my Chip and Dale dolls’ right ear bandaged up just like mine, I was sent home. When we got home I walked up to the living room, twirled around, and plopped down on the couch. My parents told me I wasn’t supposed to do that! I must have been a real handful for that period as my activity was limited. Once I got back to school I had the physical fitness tests going on. Each class my teacher would ask me if I could do something, for example walk the balance beam. I didn’t know any better and would go across the balance beam. Once home I would ask my mother if I was allowed to do that. She would tell me no. I never told her that I had already done it!

A few weeks after surgery I was so tired of the bandages that I took Chip and Dale’s off.

When we finally went back to the doctor it was discovered that my hearing hadn’t changed much and the surgery was essentially a failure. It didn’t faze me much since my left ear was what I used to hear with. However a year later my hearing would plummet in my right. But that’s a story for another day.

I still have my Incus bone. As a kid I used to bring it into school for show and tell. Eventually the liquid evaporated and I was worried. At the age of 21 I brought it with me to see my ear doctor’s successor, someone who had interned during my surgery. I showed him the bone and said it needed more liquid. He was absolutely shocked that I still had the bone and told me it was now a fossil. For 14 years I would strain into the eye drop bottle to see my bone, not realizing I could take it out. On my way home I stopped by a store and bought a shadow box. Using the Internet I printed out a picture of what the middle ear is supposed to look like. I then glued my Incus to where it was supposed to be and put it in the shadow box. This is a conversation piece in my living room now.

The only thing I am certain that the surgery did for me is tintinitus. I remember thinking that the ringing in my right ear really increased after surgery. While it didn’t do anything for me at the time it did give me a tool to understand hearing loss more. But that is part of the next story.

My Absence

As I mentioned in my previous post my reason for not posting was my very sick kitty, named Callie. Here is a picture of her before she got sick:


She came down with FIP, a deadly cat disease, and died the end of March. It’s been a heartbreaking ordeal. A month ago we adopted again. We found a black and white kitten that we have named Oreo. We picked her up because she was neurotic, or so we were told. She was a stray that had obsessive-compulsive tendencies. When we played with her one on one she circled the room as she played and made us laugh. We knew she would be a good match to our family.

When I went to pick her up I learned one more piece of the puzzle: she is deaf. Instantly her circling began to make sense. She was a stray; she somehow survived out in the wild. She circled to make sure there were no predators in her area; to make sure she was safe. These so called neurotic behaviors were survival instincts.

I brought her home and put her in the second bathroom. While she was not looking I yelled and clapped. I felt funny doing the typical hearing test on a deaf child but needed to know. She didn’t respond at all. In the past month we’ve done numerous tests. She appears to be deaf but has some hearing in her left ear. She tends to circle with that ear out and will tilt her head to allow her left ear to hear. There are no real hearing tests that can be done on a cat so our assessments of her interaction are the best tests we have.

This kitty that was described as “neurotic” is not living up to the label. They called her special, she’s just deaf. She’s now a normal kitty. She still has some of her survival quirks, I’m not sure if those will ever truly leave her. She looks behind her while eating, she circles rooms. She also meows and trills to her little hearts content. She knows what sound is, since she will meow a heart-breaking meow when she can’t find us, and stop and trill happily once we appear. Her purrs are powerful but silent.

She is in the right home. My husband and I have started banging the floor to get her attention. We sign around her and she’s starting to watch us, maybe she’ll pick up a few words. I know she’s just a cat but I feel she should have the same access to communication a hearing cat.

It’s an ironic twist of fate. I know that we needed Callie to introduce us to having a pet. Oreo needed us to provide her with a good and safe home. Welcome home, Oreo. Welcome home.
