I think it's totally appropriate to let your neighbors know what you have planned in advance. You can offer for them to join the festivities and be part of the celebration. If they're not into it, at least they have fair warning.
I have neighbors that throw a huge bash every 4th of July and every New Year's Eve. They have done it for years. They let every neighbor know what they are doing well in advance. They've lived here so long, they even let the local police know what they are doing and clear it with them. The neighbors are all welcome to take part. They are also welcome to not be home if they don't want to.
My kids and I always took part because they are super nice and it was fun. They weren't crazy....it was like a block party. We stayed, ate and enjoyed and then went home because we aren't into being out super late, but we didn't mind. It only happened a couple times a year and they were very nice about letting everyone know.
No one ever complained or tried to shut them down.
I think your best bet is just letting them know up front, inviting them to be part of the fun and going from there.
I live in the country and LOTS of people get married and have shindigs on their acreage.
Just give everyone a polite heads up.
Have a wonderful time!
Oh...I was going to mention also that in my town, we have public concerts all the time and everyone in town can hear the music. Even if they are blocks away. They just get permits for it and there's never been any problems.
Best wishes.
