My original reply was to respond only to Beethoven having oto-sclerosis
being the cause of his loss.  This seems to be cleared up in your "experts"
agreeing he has nerve damage.  Tinnitus is usually tied to the condition
a person has.  If someone has sensori-neural loss and complains of noise,
the doctor assumes it to the loss type after checking out the ear for any
abnormalities.  A roaring noise is common to neural-impairment.  Again, it
is a guessing game trying out possiblites (vascular+oto-sclerosis) with
what is known today and applied to Beethoven.
