It doesn’t sound like he’s respecting your wishes, and this is likely what you’re angry about, understandably.
He doesn’t have to understand exactly how what he does affects you, to understand that he should try and meet you in the middle and find workable compromises. You spoke up, and seem to have been ignored.
I mean, in theory he can take a call anywhere in the house, but!! he should take them elsewhere. If I were in business, I wouldn’t take calls in front of people I lived with. It’s rude, at best, and what if some of it is meant to be confidential? I don’t know what his business is, but he should still consider that.
Agree it could be you’re more sensitive to noise, but there again, your husband should be meeting you halfway. If these appliances have to run while you’re up, try and find a different time to put them on, perhaps.
