Harrigran That sounds terrible what you have had to endure. No one should end up in hospital due to noise in their neighbourhood.
In saying that I was a terrible neighbour when I first landed in this house. I'd just divorced and partied nearly every month for at least two years. It must have driven the neighbours mad. Although no one said anything to me.
Now that I am older I get frustrated by other noise. Neighbours mowing their lawns really annoys me. Why can't they all pick a day and do it all together? it's like living in Kensington Gardens sometimes. There is other noise too so when it is noisy and I want to go out in the garden then I choose some lovely music to play, brass bands or My Fair Lady cd. Not the type of music my neighbours would choose. On the whole though, if others are out in their garden say tea time, then I choose to go out later, at dusk or in the morning, like around now time, 7am to listen to the birds and enjoy the garden without it being too hot.
If you do wear your headphones Gwoof then I think you can get both telephone (landline) and doorbell where you can see a light if they ring. Check them out.
On the subject of telling the council, they do absolutely nothing anyway. We've had a problem and nothing was done. Same with police really but it is logged I suppose for any future reference but like you said, it looks like you are the trouble maker then when that is not the case at all.
Good luck with your problem and let us know how the headphones are. We might all get some! X
