Sorry to hear it's still ongoing.
We've had various noise problems in our neighborhood, and I don't bother going to talk to the people any more since one guy turned out to be unbalanced and kept pounding on my door screaming at me after I'd asked him to turn down the blasting music at 2 a.m.
Anyway, around here the police are very cooperative. They have the ethos that small law-breaking encourages people to think that larger law-breaking is acceptable. So the rule is that you shouldn't be able to hear disturbance noise from the neighbors (loud music, dogs barking) with your windows closed. When the folks next door had the eternally barking dog, it took only one warning visit from the police, and then one follow-up visit and $50 fine, for the dogs to be quiet.
You might want to be sure there's no equivalent in your neighborhood before you go to the trouble of moving. Apparently if it's a chronic problem we can escalate to the point of lodging some kind of injunction for causing an unlivable environment, but as I said, one fine always stops the behavior around here.
