Bigpops or Redmanfixit, or anyone I am working with a nearby gun range to see if we can reduce the sound from the range that is impacting our RV community. There was a post here about 2x6 frames with thick insulation posted by Redmanfixit. I would like to get the pictures of these frames that were offered and also see if anyone has seen or heard of effective infrastructure that actually helped in this regard. I would like to create a win/win scenario with the range and would even provide the sound dampening walls if I could find something that was proven to work and get some guidance how to configure it to be effective. Thanks Much for any advice!
