Is it normal to feel annoyed by my uncle visiting here or am I overreacting?

So my uncle and aunt came to our city Bangalore in India for medical checkup but its so annoying. Like this same uncle and aunt comes yearly once almost every year for medical checkup. Thats because he and my aunt lives in Falakata(yeah don't make fun of me as this is a serious post) which is 110 km from my hometown Siliguri in West Bengal in India so not there isn't many good medical facilities there. He can come to Siliguri tho which is a bigger tier 2 city or maybe Kolkata but he comes to Bangalore as he like most feels the hospitals and facilities are much better here. I don't have problem with that tho. The problem is his lack of civic sense. In home, he speaks really loud on the phone. Yeah its irritating because in Bangalore most people speak softly in phone as its polite and sophisticated but damn he speaks so loud both on phone and even while speaking. In Falakata and other towns of India, this is normal as many men do speak loud and he works in a bakery there so I guess he is used to it. He is also like those typical small town patriarchal male who believes loudness is dominance and he also tries to act controlling to my aunt there and is often paranoid about her in general. So yeah plus he is obese now too with a big tummy. He got fatty liver before too and doctors say him to walk and eat healthy but he never follows the advice and he is too lazy and still comes to Bangalore for checkups. But honestly this time I am feeling his loud speaking a lot.

I was watching a show on TV and still he walks around the TV and either speaks loudly on the phone or speaks loudly while talking with my parents and honestly its so hard for me to concentrate in the show. He is always in the hall room where the TV is which makes it irritating and on top of that he speaks loudly on phone. He doesn't even go outside to talk on the phone instead either. He doesn't care that I am watching a show and that he should go out a bit to attend a phone call. Especially after talking foreign expats in Central Bangalore, my tolerance level to this behavior has decreased. Also there isn't much privacy at times as my dad is usually working from home too with only once in a week office visit. He is usually in hall room working but as my uncle and aunt is here, he is working in the room where I am in which reduces the privacy as my uncle is always in the hall room too and thats very irritating now at the age of 25. At night too have to sleep in the small bed in the hall room as our flat is 2 bedrooms hall kitchen so in bedroom my aunt and uncle sleeps, in another one my parents so only the small bed in the hall room which is uncomfortable. Whats worse is they haven't even bought their return tickets yet so I don't even know when they will return. Is it normal to feel this annoyed?
