Carpenter buying a house on a busy road

Hi,

I'm purchasing an old uninsulated stone masonry house directly on a very busy road. The house has 2 stories.

There is a dirt mound about 3-4 meters high between the main road and the narrow street that leads to the house, followed by 6 meters of garden, and finally, the house. The mound is covered in bushes and several young trees, and stretches the length of that side of the property, which is a bit longer than the house itself. This means that there is a lot of noise coming in from either end.

I'm grateful for the mound, but it's still very loud when standing in front of the house, where I imagine my kids will be playing quite often, which has got me thinking.. the house must be reflecting a lot of sound.

I will be adding exterior insulation to the house, and originally planned on doing some sort of stucco which is what it currently has, but after looking into acoustic absorption walls made of wood, I have the idea to turn my facade into one large absorption body by playing with the thickness, spacing, layers and orientation of the wooden slats.

Does anyone have info or experience with this sort of thing?

Cheers!
