Relatively minor thing I know. Dp likes the tv loud, well louder than I do. Especially when watching a film. I wouldn't mind so much, but when it gets to the point where we can't hear each other or the dc's over it then surely it's too loud? Dd1 is quite loud at times and he turns the tv up when she's playing noisily because he 'can't hear it' apparently. I just find it too much to cope with sometimes. The TV, along with noisy 3yo and 6month old, and then having to shout over the tv just drives me to distraction sometimes and it stresses me out - I get tense and shouty. I really enjoy it during the week when I can have the tv on at a reasonable level (or sometimes off) and I can actually hear myself think.
Dp doesn't understand why it irritates me so much, but then again his parents are the same so I guess he's used to it. I don't mind the tv being on, obviously with kids I don't expect a quiet house but i do expect to not have to shout over the tv for people to hear what I'm saying to them.
