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?

Nevertheless, I would prefer to address the problem directly rather than solve it through software.
Does anyone have experience with the products from "ligno"?

As far as I know, @hampshire (last seen around Christmas 2021) https://www.hausbau-forum.de/threads/gesund-bauen-was-ist-wichtig.41236/page-4#post-527295 and @rick2018

From the interior side, however, I don’t see any surface that might absorb sound—just wood.
The acoustic elements are more designed as "resonators" for sound, so the effect should not rely much on the "casing" itself ;-)

Not personally. Only through my clients. It works well but is very expensive – however, a normally furnished living room serves the purpose at a fraction of the cost, and with clever use of sound absorbers on the walls (decorative items or as artwork), the living room performs better than ligno.

Unfortunately, most of my windows don’t allow for hanging pictures, and on the wall in front of the TV, I don’t want to hang too many items.

The lignownad won't do anything for the bass range. It can only help with treble and slightly with midrange frequencies. However, those frequencies carry less energy anyway.

You should look up Helmholtz resonators; in my opinion, that would be the best solution.

However, using the onboard options to tune the sound system to the room would be the first step. Structural measures are not off the table though. Hard walls and large window areas definitely affect the room’s acoustics.
