Having a DJ for a home party may seem like a great idea until the neighbors complain. In some cases the host may get arrested if the noise does not stop. To reduce noise for a home party for the neighbors either the host or the DJ can provide decorative quilted sound reducing blankets. They work by absorbing sound when put in between the noise and the neighbor. Of course it could be that the police officer when called may arrive and start dancing but that is less likely. Most likely they will measure the sound and ask you to turn it down.
If you hold parties often you may prefer sound fencing. Below are some items to help for DJs and hosts.
