Which masonry is suitable for noise level range III

These bricks are ALWAYS to be discouraged. They are truly acoustic hazardous waste.

Then does sand-lime brick probably make more sense?

When it comes to noise, they are the ultimate. And summer heat protection is also the best thanks to a lot of mass, if you provide proper shading. You just have to accept the ETICS. For noise on the outside, it would be my first choice. By far.

Certainly, but there are people who do not want ETICS. Then the filled brick with mineral wool or perlite is a very usable alternative.

WDVS??

What exactly is [WDVS]?

Thank you :)

What exactly is WDSV?

Thermal insulation composite system. So, insulation applied to the bricks – it can be "plastic" (i.e. classic EPS), but also mineral wool boards, resol boards, vacuum insulation panels, etc.

Sand-lime brick + MW + clinker, if we're already talking about the ultimate.
