When setting up or optimizing a studio, it makes sense to measure the room with a measuring microphone and software such as the free Room EQ Wizard. This gives you an overview of the problems, both by looking at the frequency response and the decay times, for example, in a waterfall diagram. Of course, we can also calculate modes, but the reality is often different due to thin walls, windows, doors or other factors.
The calculation is only correct for walls that are 100% soundproof. Besides, it is not always the case that every fashion that is theoretically there is a problem. In many cases, where the first axial mode (explanation see below) is quite low, it is excited so weakly depending on the speaker, that it has little or…
