It depends what has caused the tinnitus eg. scar tissue,nerve damage or idiopathic.
Maskers can be used (look like a hearing aid) but there success rate is not very high, they can make the wearer very withdrawn.
Remedies I have used include Kali iod,thiosin,salicylic ac but none to much avail.
Constitutional treatment does not seem to have any effect either.
I would be interested in hearing others experiences.
