Having very unequal hearing, say 90/10, or in my case, no hearing at all in my right ear, is VERY DISABLING because you can't instantly "localize", which is a Most important thing for survival. (If you have hardly any hearing in either ear, all is quiet, which isn't a bad thing, because there are devices that can give you back volume for both ears, and equalized, saying you have the doctors and money. that's where programs like ssi and others can help with the burden)
You have to hope you can turn your good ear at the sound quickly, and your head becomes a moving "radar dish", but it's impossible sometimes. You will hear a helicopter coming, but sometimes not be able to locate it, and then it's gone, and you will feel physically disabled at that moment,
and then there is another voice or sound to pay attention to. When you are in the home, all the sounds of the air conditioning, reffer, dish washer, wife yelling from the other room, dog barking, doors closing, tv on, they are amplified, and coming from 360 degrees. Some one, out of sight, can call you, and you may turn the other way at first.
The moment, my left ear lost his brother right ear, was traumatic. If people are talking and turn their heads, you lose the voices, and they are impossible to fully understand. You will hear 3 words from over there, and 2 words from over here, and by that time be totally confused, You will find that if you are not locked eyeball to eyeball with some one, you will be a step behind the conversation, even in sign. Being Deaf from birth and never hearing spoken words, must be a great advantage some times, with the millions of words coming in, and all the hype, you don't need to cypher. It's all about the corners of your eyes, and the corners of your mouth. they are the truth tellers, and your eyes will develop x-ray vision. Able without the diss.
