Wearing a aid to enhance sound, like the Walker Game Ear can help, but it does not mask sound. Tinnitus is caused by a loss of high frequency hearing, and the brain creates the sound, it thinks is missing, but screws things up doing it. Masking replaces the sound you hear with another that is less noticeable.
After decades of firearm shooting without protection my hearing was shot. There were a few incidents, shooting a short-barreled 44 mag, other guys touching one off with their barrel inches from my ear, when it physically HURT for days afterward.
My Christmas present for '08 was to visit an audiologist. First a Doctor checks you out for physical damage,for some people hearing loss is wax build-up, others can be fixed with surgery. Most of us need hearing aids.
After a long consultation, preceded by a hearing test were they put you in a soundproof booth, put headphones on you and test for your range of hearing loss, I chose a behind the ear model with a volume control. My decision was based on my hearing graph which showed that my low frequency hearing was normal for my age, but my high frequency hearing was, as the Doctor said, "Pretty crappy".
So, what they do is, they program your aids specifically for you. In my case low frequency sounds are not amplified and are allowed to enter my ear around the speaker. Only the high frequency sounds are amplified as the graph indicates. If your graph is a straight line, all frequencys being shot, then you should probably go with an in the ear aid. Some of todays aids are so high tech they can "talk" to one another, and with your bluetooth, and with your MP3 player, etc. Amazing technology!
Now, a year later. My quality of life is better. I can converse with people. I can hear the blinker on my truck, birds singing, frogs peeping, bugs chirping and best of all, deer walking in the fall leaves.
It started as MY present, but the whole family has benefited.
