I have tinnitus but it comes from shooting guns for over 30 years and using power equipment. Anyway, there is something on the market now called Quietus (
Quietus for Tinnitus Relief | Welcome! Find Tinnitus relief products, as well as other ear health products and information.) that is advertised to silence the ringing. I don't know if it works or not since I haven't tried it yet, but it might be worth a conversation with your doctor.
