Noise cancelling headphones with conversation ability are the best noise reduction mechanism for noisy environment. They will cut out junk but let certain frequencies through like voice etc. There is a gizmo that will listen to ambulance etc sense em coming and start flashing to let you know as well. Tires make a heck of a lot of noise as well. All the best
RUSTIC is good.
Kudos to those who make Local, State & Federal Parks & Campgrounds possible and to those picking up the slack by Providing Private Campgrounds.
