Unfortunately not a new idea.
Here in Scotland there are a few ranges with problematic, pain in the arse, anti gun neighbours. A common method of lessening the 'boom' (other than using moderators) is to get two blue, plastic barrels. Cut off the tops and bottoms, stick both together to make a long tube and line the inside with the triangular pattern , noise cancelling foam.
It surprising how much an effect it has, when you lie behind the barrel tube and shoot through it. It won't seem so to you, but the others around you will notice .
