Hi, I've had experience being put in-charged of soundproofing an event. I thought it was impossible to soundproof the area of a backyard, but I did it with these noise barrier walls. They are easy to use and aesthetically pleasing, you must try it out if you are trying to soundproof your event. It is easy to setup and their site even has support and a blog incase you need assistance.
Soundproofing your even makes a better event, and improves your reputation. In your case, a party, you can prevent complaints of loud noises. It is also waterproof and weatherproof so you can also leave it in the rain like I did.
