Now that I have both layers of SoundScreen© acoustic insulation batts installed, time to run another room acoustics analysis, to measure the room response.

Quite a surprising but expected result, while I compare the measurements from the past two tests, first when no insulation, second with first outer wall insulation and now final inner wall insulation.

We look at the result of the graphs in detail.

Finally, a small plasterboard and vent installation comment and tip.
