I really don’t think it is that loud, just how maybe speakers are on the shared wall. Again, I think they would be modified to know it bothers us. Until Thanksgiving when it kept my daughter from falling asleep, I really only noticed it on the weekend, and then, not at a late hour.
If there is a noise ordinance, I am not aware of it. I do know a previous neighbor 2 units down asked if the people between us kept us up at night. They were a young couple, and according to the complaining neighbor, their tv was blasting at night. I heard nothing, the TV wall was a shared wall with the other unit, not mine.
I know we need to say something, I just feel badly complaining. When we had a dog that barked more than he should, I had asked them to let me know if they could hear him, as at the time, I didn’t know if the sound carried. They were very nice and said they never heard said dog; don’t know if that is true or not!
