Hello
We are going to build a 40m long noise barrier.
The idea is to make ready-made sections 2x2m which are then just screwed between the posts.
Has anyone built their own noise barrier? Structurally speaking? Träolit? Stenullskiva?
Yes, someone must have done this, I can't find anything!

The option I have considered is to only use overlapping horizontal battens 28x45 on the inside and outside of the fence. Will this have any noticeable effect on road noise in addition to visibility?
The fence will be directly next to a country road, 40m long, and the lawn is on the other side.

Noise barriers can be made in two ways: hollow (reflects) or with insulation, which absorbs, and absolutely not as you described as a suggestion. They must be completely sealed. So you even need a base at the bottom. Check along the roads and you'll see.
Everything else is more cosmetic and makes very little difference.

Not a super expert but no, I think the effect of the results is barely satisfactory. Imagine a forest, it doesn't protect against a highway, those won't be enough.
I think a round on Google will give better answers than I can. But I can say that it's quite expensive. Much more expensive than a regular one.

My wife works with noise investigations, among other things. Here are some tips:
- It must be completely sealed. No gaps anywhere.
- As high as possible.
- Build with a sacrificial board at the bottom, so it's easy to replace when it has rotted. It needs to be partly buried in the ground.
- Absorbers are mainly used to dampen reflections. It's not much use to incorporate these into the fence; they need to be on the outermost layer. The typical case is railway noise barriers. There, the train acts as its own noise barrier, and the sound from the wheels bounces between the noise barrier and the train. Surface absorbers can then reduce the bouncing. If you don't have a subsidy from the traffic authority, I guess it's not worth the cost of real absorbers.
