Quiet neighbours now making noise.

I think the noise caused by your son and the noise caused by your neighbours both fall within in the realms of normal, acceptable noise. If it was 2am every night then this would be unreasonable.

Please could some one tell me what "this is a reverse" means??

To be honest, I'd probably do the same if I were them.
The high-pitched thud thud of a basketball is a really irritating sound. I'm not surprised they decided to reduce their own attempts to live quietly.

Petition the council/local park authority to add a basketball hoop to a existing court.

Three or four times a day of the basketball bouncing for half an hour at a time and you're getting pissed off about their radio playing for a few hours a day? Are you serious?

Do you realise that they can probably hear the bounce of the basketball above their tv?

You are definitely being unreasonable and antisocial too. Why can't your son go and play basketball at the park?

Yes, because you say it's a noise that is very common, expected and accepted in the states.

And one that people probably make themselves if most homes with kids will have a basketball hoop.

Over here it's not nearly as common, so is a lot more grating and intrusive for people to have to listen to.

Suspect the difference in proximity of houses to one another makes the difference.
That and the average size of houses which makes it harder to escape a noise which is starting to irritate.

Brits are really precious about basketball noise. Almost every driveway in the US with kids has a hoop. Or they drag it into the street. Honestly, it's fine.

So he plays pretty much all year and all they've done is sit out in the garden for a couple of hours listening to the radio while the weather's been good. Is this a wind up ..

I’m with you on this. The repetition is like Chinese water torture. I have a neighbour who constantly smashes a ball against a fence and it really gets to me.

Totally agree.

Four lots of half an hour is two hours, so you’re equal!

He plays basketball 2 hours a day, they play the radio for 2 hours a day. It'll be winter soon , does he still play.

Three or four half hour sessions per DAY is horrific.
I would tolerate three or four per weekend.

Two hours of basketball noise is a terrible thing to inflict on your neighbour.
Hearing music a few times per week is nothing unless it is extremely loud or played too late or early in the day.

An idea. Bargain with neighbour about times to play basketball matching their music playing times. Can you all agree on a session per day when music and basketball is played at same time? And no other playing apart from that.

Oh god the sound of basketball bouncing is so annoying , I wouldn't put up with it a few times a day. Sounds like your neighbour has reached the end of their tether.

this might help

Im sorry but the fact you are still wanting him to do this every single day when its not even a training thing but just for fun, you still seem completely unaware of how annoying this is for most people.

I would have had a little bit of understanding if this was his team sport but this is just for fun, a couple times a week is more than enough, any more and you need to find a park. There are areas that basketball in gardens is banned for good reason, the thudding is relentless and such antisocial in terms of noise.

How can you not see that after all these posts?

Could you put the basket above the garage and your son bounce the ball on your drive?

I reckon the genie is out and the neighbours have established a new norm. I don’t think you’ll be able to coerce/convince the neighbours to change their liberating practice.

The thing is, while you have kids, the garden should really be designed around family needs not what looks pretty. You get your garden back when they're grown up.

And I say that as someone who loves to garden, with a 2 year old who just loves to pull the heads off all my flowers to make potions.

You accept that you make the space work for the family at whatever stage you're at.

That sounds like a positive start.

It's actually credit to you that you have taken what's been said on board.

That doesn't happen a lot on here.

I'm sorry but I can't believe this, no-one can be this far up their own arse that they think this is acceptable right next to someone else's home. Basketball hoops and trampolines are the two things that should never be anywhere near other people's houses.

Grass and flowers can be regrown.
They aren't as important as consideration for your neighbours.

I'm glad you've decided to apologise. Our garden is an odd layout so has borders with a few houses, we've got noisy young children in one, student let who has parties in another but without a doubt the only house who's noise bothers me is the lovely family whose kids play basketball. We haven't said anything because they are fantastic neighbours in every other way and I know they'd be mortified amd stop the kids playing, but the incessant thud thud thud is horrific. I've been known to "forget" to throw the balls back for a few days for a break at times. I'm resigned to having to keep my windows shut wfh every time they are out in the garden, I think like you they also limit the amount of time playing but it's so fucking annoying. We've joked about wishing they'd take up something less antisocial - like bagpipes or saxophone.
