"Distant" highway noise mitigation - any success stories?
Has anyone ever had success with mitigating highway noise coming from farther away, esp. when carried by the wind towards your rural property?
I am primarily concerned with outdoor enjoyment.
I have hundreds of meteres forest between our property and the highway (they do something but it still sounds like a racetrack next door when the wind blows towards us). I have planted additional dense forest hedges (they do nothing).
I have explored berms and fences (they apparently do nothing unless right next to the highway), which is not allowed.
I am now thinking that acoustic half domes as micropockets of calm, literally where we can sit under a covered roof with the only open air side facing away from the highway, may be the only feasible solution available.
Even a giant berm near our property line will supposedly only drop DB by 3 according to one acoustic consultant.
I am desperate and looked into selling but that would be a disaster for many reasons.
Would be interested to hear any success stories before I get driven off property from sheer annoyance. #home
