New construction extremely noise-prone or sensitive to sound

Yes, do you have a few tips then?

He does: he has already praised his Lignotrend ceiling several times, and also the Helmholtz resonator twice.

the room is simply square

In this thread?

I can imagine ligno Trend in an open roof structure but not in a completely normal 20sqm room.

The gym probably doesn't need to look so clean, right? You can do something with some heavy fabric.

That means curtains, I can't think of anything else, carpets are already laid... I'll take a look at how to build such a resonator, do you need special equipment to measure it or can a layperson do it too?

We also have it in the fitness room and also in the 20m2 pool pavilion. Looks great. So no problem with the size
