Sound Abatement in Arizona

Sentinel Range Service was called into action to solve a problem for a government building in Arizona where the range was in the basement and the offices above were having problems with noise coming from the range during training sessions. The existing abatement wasn't helping so they asked us to fix it.

We suggested installing PePP. PePP has an NRC of .70 (Noise Reduction Coefficient). That is the second highest in the industry and for the money is the best option. Sentinel Range Service is one of the top providers for PePP in the industry.

We decided to remove all existing "egg crate" foam from the range and some of the damaged rubber ballistic tile from the range wall and replace everything with fresh updated sound abatement material.

The flat baffle and every wall behind the firing line was removed and hauled away. Under the flat baffle was a layer of plywood, however, under each wall was painted cinder block where the original install was glued with construction adhesive. We had to remove as much adhesive as possible to get a nice flat surface to adhere the new tiles to. Will this task accomplished, we moved to the baffling. Each baffle had the foam product glued to the plywood mounting surface where acoustic would normally go. We removed that and scraped for a clean surface.

Now, it was time for install. For the cinder block, we also used construction adhesive but added a layer of spray adhesive to keep it in place so it would not shift giving us perfect seams. There were also stall walls, doors, windows and target components to worry about. For those places we cut the PePP to the perfect dimension to cover each odd shape perfectly. Next, on the first flat baffle, we used some spray adhesive and some fasteners to install the horizontal pieces.

Once all those tiles were installed, we moved to the rest of the baffles using a similar method as the flat, first baffle. Spray adhesive and fasteners.

Once all the baffles were covered we started installing the ballistic rubber tiles on the wall. They come in two types of rubber and multiple thicknesses. We used 2" non-self healing rubber.

Finally, we got everything finished and looking fantastic! We had a little time left over so we decided to check all the targets and the trap and make sure that we left everything cleaner than when we found it. The courthouse has not had a complaint since and the Marshalls couldn't be happier with the outcome. They have asked us to come back and fix their trap later but that's a different story for a later time!

Range Mastery, Mission Assurance indeed
