Hi There
Can you be a bit more specific as to what drugs your husband has been on?
Tinnitus is a side effect of certain anti-cancer drugs, but also a whole range of other drugs including some quite common agents. So often it is a combination of some of these, that results in hearing loss. The tinnitus was explained to me as the brain manufacturing noise to make up for the higher frequency hearing loss as a result of toxicity to the hearing mechanisms by the drugs. So not only do you have the ringing in the ears but you no longer hear the high frequency sounds, making it hard to distinguish between certain sounds and others.
In my case the tinnitus was a side effect of blood pressure medication. Most of the time I no longer notice it, that is I just tune it out. But there are times I am amazed that other people can't hear it it is so loud. Having background noise, e.g. radio on, helps you not to notice it.

Lord help ’em, how I pities them
Unhappy folks on shore now!
