I started losing my hearing at 50 years old. I think it was due to all the 'rock and roll' loud music I listened to as a teen and the fact that I shoot shotguns for clay pigeons and birds for sport. Unfortunately, many times I did not wear my hearing protection. I also worked in a manufacturing plant for 17 years and sometimes was exposed to noises that may have hurt my hearing. I have no doubt that I did this to myself.
When I started having problems, my boss actually asked me to get my hearing checked, as I was misunderstanding some comments and not hearing all that was being said, especially in teleconferences. I actually did not realize this was noticeable to anyone. I was in management, so it was not a good situation. I got checked and ended up getting a set of hearing aids, I paid over $3,000 for the pair, and they were not the most expensive ones available, they were middle of the line...
The first time I put them on, I suddenly started hearing a bunch of sounds that I did not recognize. One example I remember is when I started driving home, I heard a loud noise, seemed to be coming from my side of the car. I thought something had gone wrong with the car. I pulled over and checked all around and in the engine for the noise, found nothing! When I got home, I asked my wife to ride with me to help figure out what that noise was. She heard nothing and thought I was losing it! Finally, I figured out the sound was the normal sound of wind whistling on the window of my side of the car. This is a normal sound that most of us just ignore or don't notice. My mind had forgotten what sound that was, and since it was amplified, my brain could not recognize it. As time went on, I found I had to 'relearn' a lot of sounds. Within a few days of wearing my new hearing aids this all went away. They actually helped me a lot at work and home. I could not hear as well as I used to but much better than I could before getting them. I am now 20+ years older and I still use these old hearing aids, they still help me enough for me to do all I have to do.
If you get real hearing aids, and not the plain amplifiers, they will help you if you are willing to go through the adjustment phase. It is hard to get used to them, but they do work, once you get used to them. Prices on these hearing aids have dropped dramatically since Congress changed a law that now allows makers of all hearing assist aids to advertise and compete with the original manufactures. But, beware, the hearing assist devices will not give you the help you may need, although they sure are better than nothing. Shop and be sure to get a hearing aid that has to be set up for your specific hearing problems, but you do not have to pay $3k anymore...
