Young deaf kitten won't leave old hearing cat alone

I recently (within the last 4 weeks) adopted an adorable pure white deaf spayed female kitten from a friend who was unable to care for her bc his dog thought she was a fun chew toy. I already had an eleven (11) year old all-grey neutered boy kitty, who I have raised from his own kittenhood. They get along better now than their first few days together, but I am still noticing a recurring problem. My deaf girl simply will NOT leave my older hearing boy alone! I had read that female cats tend to establish dominance over males, but that does not appear to be the issue here. Deaf kitty is not in any way aggressive or even assertive, but whenever she gets too close to hearing kitty, he hisses and growls like something possessed by a demon & snaps at or bats at her (both are de-clawed, him due to the fact that I didn't know it might be considered cruel 11 years ago & her because her previous owner wished it). However, she cannot hear his hiss or growl & also seems unfazed by his physical attacks & bats back, but not aggressively; she appears to only want to play even though he's actually struck her more than one of the times he snapped at her. In fact, he will get upset & retreat under a coffee table, whereupon she will become sad that he's not "playing" with her and begin meow-ing plaintively.
My question is, of course, HOW do I:
a) get my older boy cat to like the new deaf kitten because she clearly adores him? OR
b) get my deaf kitty to leave my poor old man alone?
I have already sprayed her with water on her flanks when she pursues the older kitty & I have already shown "preference" for the older kitty when she sneaks up on him, to no avail.
Help!

I should mention that the older boy kitty never attacks the deaf girl kitten on his own; only when she gets "too close" & actually invades his personal space. He will growl if she gets close, but of course she cannot hear that. However, she will "attack" him regardless of distance from one another, but never, ever, in an aggressive or territorial way. She really seems to be fond of him, which hugely annoys him! Also, they share a litter box (their own choice; they both preferred the newer one) with no conflict & are able to eat at the same time from separate but very nearby bowls. Thank goodness no one has gotten hurt or seems likely to get hurt (again, both declawed, & he's as yet not bitten her in earnest - & any time he'd bitten ME in the past, he merely snapped & then licked it "all better;") ::crosses fingers:: ! However, the vet estimates her at about 7 months and she likes to gnaw gently on my knuckles if she's sitting on my lap while I work on the computer (like right now), & I think she may have done this to his tail once or twice recently.

Please, ANY guidance is appreciated!
