Some counties have strict standards about traffic noise level limits in condo courtyards or backyards.
We recommend a 6-foot noise wall that'll fix thier noise problem (for 5 foot ear location) and make it meet county standards.
Them: Can we move the wall so it does not completely cut off visibility of the road?
I think an earplug dispenser at the edge of the building will fix everyone's problems.
Or a plexiglass wall.
