They can’t enjoy their own garden on a summer evening. I hate people who inflict their noise on others. Try to think of someone else and not yourself OP
Unreasonable noise levels need to be addressed. But everyone is allowed to enjoy their garden how they want to and some noise is a given.
We have constant problems with one next door neighbour in her 60s about our noise. Before us, a retired couple lived here for decades, she'd been used to absolute quiet. We've now lived here for several years with 3 dc and no, we're not silent.
I've had complaints about the children laughing too loudly, about the trampoline (which is as far away from the fence as it could be) about the noise from a Sunday BBQ (ie talking and laughing of 9 people, wrapped up at 5pm). About DH pressure washing the drive (2 hours Saturday afternoon) about a ball bouncing, about sounds of the dog 'running around' (zoomies, panting, NO barking), about the noise of the garage door opening and closing.
Basically everything. We're just a normal family making normal noise. Not 'chavs' or party animals or with feral kids that scream. Just talking, laughing, doing garden chores, socialising with fairly quiet friends very occasionally.
We ended up in a blazing row a couple of years ago after she gave me a mouthful of abuse as she'd 'cracked' apparently. I told her if she wanted permanent silence in her garden she shouldn't be living in a 4 bed house alone in a family area and needed to get herself to a bungalow in the retirement complex down the road.
After that we had the community police turn up 3 times in a fortnight due to her complaints until they told her she was wasting police resources and to stop calling them 😂
If you're going to live near people, you're going to hear people. Shocker.
