What to do about noisy garden parties after asking nicely (twice)?

I live in a terraced house on a quiet street with small back gardens. My newish neighbours, once removed, like to have garden parties with a huge outdoor speaker playing some very lively Eastern European folk music. They also like to leave their young children out in the garden early in the morning and they literally scream repeatedly (before 7 AM today). It’s several kids and many adults in a small house, with even more people at the parties. In fairness they wrap things up by 9 or 10 usually, but they start around midday and it’s loud enough to come through closed double glazed windows (which is annoying in the summer).

On two occasions I knocked on their door after several hours of music when I could hear it on the other side of my house and they turned it down, but I did get screamed at by one of the women in a mixture of languages.

This happens a couple of times per month. It’s not late or regular enough for the council to get involved. I work nights sometimes (paramedic) and the bass means I can hear it even with earplugs, especially if the window is open, so can’t always just go out. They’re not next door, so I can’t just make noise to get them back. Ant suggestions?
