Hi, Try This, put a foam ear plug in your good ear , nice and tight, and listen and feel it expand in your ear, takes about 25 seconds. It blocks about 95% of sounds in the mid and lower range. Walk into your class room and see which voices that you can't hear. Now, you can't have ANY hearing in your left ear. ( you lost yours overnight, I lost mine in one second). either way, lost, for now.
With me, the lower male voices and sounds, go away first, then other voices and sounds, like fans and equipment, etc.,
go away, then what is left is the higher range of the female voice and some "higher" male voices. All of a sudden it's quiet, and you can understand the few voices that you can hear, instead of all the chatter. And then go up to them or look at them, and talk to them with your eyes and your hand movements. That was a start for me to gain my confidence back, and since we're 1/2 deaf we might as well learn from ALLDEAF.
After you get a feeling of what its like to be in a relatively sound proof booth, (for short times) with your plug in,
do what I did, and buy a "wireless bone conduction headphones" ( Aftershokz, Air), and pair them up with a Kindle Fire, position the head phone on top of your ear plug, click your Kindle to YouTube and select your favorite old time music, put it in your back pocket, (being hands free is really important to me to feel comfortable ) and as soon as you hit play you will go into another world , especially if you really enjoy "listening" to music. Then take the plug out, and position the "AIR" in front of your right ear canal and play around with being able to "hear" things from any position on your skull. higher tones, but there. When the phone is moved a little bit towards the actual ear, all the bass comes in, it's cool. I only have one ear, and as bad as that is, I actually think that I hear "better" now. I'm so old school, the music that was on my Kindle when I first got the "AIR" was "Dark Side of The Moon, and The Alan Parsons Project". my today music is YIRUMBA Piano music, and A-432 tuned music. just sounds more comfortable. It's interesting to talk to people and still have soft music behind your ear, which you can control the volume to.
I think that tuning and harmonies are the search for perfection, and good on ya for passing these on to kids. the more the better.
Try this out and see if it helps you more focus on voices...and music, that you choose to hear, and let the Tinnitus and noise go much softer.
and oh, I'm sleeping better, when I get up at the same time in the morning no matter what time I went to sleep, and have a Protein shake or some eggs first thing. and stay very hydrated. stress burns more water than you think. get back with me maybe.
