Is it a hearing problem or ADHD?

It seems that my husband doesn't hear the noun in the sentence!  I know this sounds a bit crazy, but this is my life. When he does hear, his interpretation of what was said is not what is said. Yes, he has taken many hearing tests and everything is fine.  At this point he finally agrees that something is wrong, particularly when he hears me say things I've not said. I would like to know if this is all ADHD or is it signs of something else?
