Sound insulation in 3D

Sound insulation in 3D

One of the most challenging aspects of building acoustics is that sound insulation and sound transmission paths are present in all three dimensions, when flanking transmission is included. If you have two rooms next to each other that requires a certain sound reduction index R´w in dB between them, the first thing that comes to mind is the directly separating construction, i.e. the wall between them or the floor structure. Most of the time, you will be correct, as this is often the most important transmission path. Hence, it is easy to miss that sound transmission occurs in many other places in a real building, which are not obvious at all when looking at a 2D drawing.

Why an acoustician should use VR

If you are an acoustician, you might recognize the following scenario. You have been involved with the design of a building, perhaps for years, and think you have a pretty solid understanding of the building. Yet, the first time you do a site visit you will probably think ”Aha, so THIS is what it looks like in real life!” Personally, I know I have had that feeling every single time. With acoustics, this can be a proper challenge. We obviously need a tool that can help us bring out that crucial ”gut feeling” in the design phase. If we have to wait for the site visit to the finished building until we can consult our gut, it is often too late because the critical decisions have already been made. So how can we solve this?
