Im not a physcian but I have done lots of study on tinitis and it is not  
related to too much CW altho IT MAY have developed from too loud a volume  
especially with headsets.  However, it's kind if moot (not mute!) since  once you 
get it you can't reverse it.
 
Tinitis may affect your abilty to copy CW however. Medical hearing tests  
prove this.  If the "ringing" from your tinitis is 800 hz then that will  "cover" 
an 800hz note - and interfere with closeby notes.  Tinitis pitch  can vary 
from low to high, however, and some tinitis is buzzing, not clean  tones.
 
One interesting treatment for severe tinitis by the way using the out of  
phase nulling technique similar to an MFJ 1025. It feeds back the tone of the  
tinitis ringing out of phase but this device is fairly cumbersome and not  
practical for routine use with common tinitis.
