ᐅ Acoustic ceiling for reducing echo and reverberation

Topic: Acoustic Ceiling:
Many people are familiar with those wood/felt panels from hardware stores and similar places.
It is clearly noticeable that the felt reduces the reverberation in the room.
However, I prefer the look of the "Ligno" system.
From the room side, I don't see any surface that could absorb sound, only wood.
Does anyone have more expertise on this and can tell me to what extent this can reduce reverberation in a room (in my case, a living room with hard walls and very large windows)?
Would adding additional insulation wool behind the panels result in greater sound absorption?

New Construction – Please consider the residual moisture in the concrete ceiling, risk of mold.

How long should one wait before installing the ceiling framework beneath the concrete slab?

It’s best to monitor the moisture with a moisture meter.
Basically, wait at least one winter; after that, it’s usually safe to proceed. Of course, don’t forget heating and daily short ventilation (shock ventilation).

If you want to do it properly, it needs to be calculated. There are acousticians for that (I can gladly connect you).

Just throwing out the idea of placing a subwoofer here and there and some speakers somewhere is unlikely to achieve the desired result. Sound is ultimately a fairly balanced combination of room acoustics and the right technology. The world of absorbers, diffusers, and other acoustic aids goes far beyond the narrow scope of acoustic panels.

There is a solution for almost every acoustic problem; you just need to decide how important the topic is to you.

After you’ve now received four pages of useless furnishing tips, I can say something about Lignotrend. An acquaintance uses their products for his wooden houses, partly also in kindergartens and training rooms. Very good quality, made in Germany, with certifications and professional advice, clearly better than any DIY solution, but expensive.
