My neighbours play music, have friends round, cut their grass, talk, splash in a paddling pool. All of which I don't mind, I don't mind their music and means I can put mine on too.
There are usually several cats (sometimes mine) having a face off in the gardens, I can hear the other neighbours motorbike and dog barking sometimes even late at night but it's never relentless.
I also live next to a small park where all the kids from the estate play including mine and I can hear the high school bell which goes off several times a day.
Right now in my garden there are 4 children being noisy, not screaming but just being loud. I will definitely not be telling them to keep it down, they are having fun.
We sometimes have a BBQ with music, last year I did have a party with several friends and a hot tub but it was pretty much over by 9. This year I'm getting another hot tub but just for family use for a bit. I'm sure I would be the neighbour from hell because of the hot tub and the kids but the kids are in by 7/8pm and I can't see me and my husband being in the hot tub past 10pm, earlier on a weekday and it is only for a week.
I think a lot of noise is give and take, some things might be annoying but as long as it's not constant and every day and at some ridiculous hour then we just need to learn to deal with it.
