I'm kinda the opposite or maybe not? Next door has 4 ranging from 18 to 8 and she's also a childminder and she has a pool and a trampoline and pets and yet I've only ever had two issues with noise. Eldest having a few drunken parties until 4am and counting, and when one of them kept booting a ball off the fence. Otherwise grand, don't mind the mindee toddlers chit chatting, laughing etc and the older kids having fun. All very normal.
We have quite a lot of kids in the street, regularly out playing 99% of it doesn't bother me, when about 4 of them all decide to play basketball but each have a ball and bounce bounce bounce and nothing in rhythm but overall I'm genuinely happy to have the kids all out playing, same as my own did.
But, and it's a big but, we have a family that moved into a house to the (diagonal) back of me, in the winter of 19 with a toddler and a young baby. Come spring and lock down, shouty dad and very loud toddler out from the crack of dawn anytime it's sunny or at least warm and dry. Now there are two of them that get catapulted out into the garden anytime from after 7. Shout and scream in happiness for a few minutes, then shout and greet for about 10 then get taken in. It's literally the first thing I hear every day and i'm generally a pretty good sleeper. They are just really loud and dad seems to encourage it. Doing my nut in but there is really nothing I can do that isn't petty, nasty or illegal - don't think I haven't thought about all of those things though.
