AITA for watching “The Nanny”

I (43f) love the show "The Nanny" but my husband Brad (44m) doesn't. He says Fran's voice gives him a headache, which I understand since he has a condition where he's sensitive to some sounds. Usually I watch it when he's not at home so there's no arguments.

Today I decided to watch it even though he was at home. He was in another room and I began to watch. He comes out 10 minutes later and asks me to turn it off or at least turn it down (I cannot hear well so I usually have the volume at 45-60 so I can hear the tv.) I said no because he could just go into the other room and he said he could still hear it from there.

I argued with him about it but eventually he decided to lock himself in the spare room and won't let me in. AITA?
