After a week of continuous ringing I theorized that the wild frequencies during the phone call screwed up my ears' micro-hairs, and that perhaps coaxing them back to harmony would take the opposite kind of sound frequency - a single balanced continuous tone (along with self-healing affirmations and a belief that my ear was healing). On youtube I found a 528 hz solfeggio frequency tone (just a single continuous tone) and played it over and over via good Bose headphones. After two days my tinnitus abated considerably. I have to mention at the same time I started listening to the tones, my devout grandmother prayed for my hearing, so whether it was the 528 hz tone, the prayers or some other factor (additional vitamins, garlic oil in the ear a few times, and CoQ10 supplements), I do not know. My ear is still sensitive to high pitched squeaky sounds and I wear an earplug to give my ear a rest, but the ringing is probably only 5-10% of what it was two weeks ago and I can live with it, whereas I could not before. I think the first step is believing you can be cured, rather than listening to doctors who say it cannot be cured. If a cut or broken bone heals, so can your ears.
