I've been thinking of building a one person box to help reduce overall noise while target shooting. While suppressors for every weapon I own would be cool, it's not financially or physically practical. I love loading up the family along with friends and their kids to go out on our land to do some shooting. We usually have food, grill out, etc.. however, some of the rifles and even some pistols can be quite loud, even from 100 feet away. So I had thought of building a box with three sides and acoustic tiles to try and direct sounds away from the food/recreational area. Anyone done anything like that? If so, did it help at all or was it just a waste of material? I've even wondered if a simple freestanding wall between the firing line and the recreational area would make a difference.
