I can tell you for sure, 100%, landscaping WILL not
block the noise....it will only affect what you see (or not).
We had originally put in very dense and I mean DENSE fast growing shrubs which did in fact create a "wall". It was great to not have to see the traffic. The noise was unaffected. Eventually TV constructed a 7 foot wall......even better, now that we have a back drop to put plants against. Noise reduction....I'll be generous and speculate a 20% reduction.
There are very few home locations in TV where one can escape, totally, road noise.
What you will find happens is you adjust. You will soon not even hear it except for some red neck truck with blasting duals or a nut case moto cycle trying to break the sound barrier.
If you can see the traffic, you will hear it....you can block the sight, but not the sound.
