That's a tough one, I'm in a similar position at the moment, but instead of the ball, our neighbour likes to start his V8 drag car (extremely loud V8 drag car!) up at 6am, and then at 9pm, and then 2am, all the while waking my poor DS up as his window is right next to the garage! So I feel your pain, trust me
Pretty sure that's a violation of noise laws, none of those times are in the allowable period.
