ᐅ Lower the ceiling using an acoustic suspended ceiling to reduce sound transmission.

Experiences are incorporated and can be shared by @hampshire and @rick2018.

There are many options. Most acoustic ceilings are more suited for offices.
Choosing one that looks good and unobtrusive is already more challenging.
We installed acoustic ceilings from Lignotrend (silver fir) throughout the entire house. It was an excellent decision.
They look great and, above all, there are no sound issues. We only have hard surfaces (glass, concrete, asphalt...).
Guests always notice the pleasant acoustics.
@hampshire also uses the Lignotrend system.
Since you want a suspended ceiling anyway, the additional cost isn’t that “extreme.” The substructure and installation are more complex, so it’s best to hire a skilled carpenter. In return, there’s no drywall, filling, wallpapering, or painting involved...
There are also flush-mounted LED strips available for this system.
I didn’t want a modular ceiling or perforated panels in the living area.

You can see pictures in my construction thread.

In my opinion, this is more suitable for public spaces and/or offices rather than private homes, right?

No, especially if you want good sound reproduction at home with many hard surfaces (although I have no idea about your expectations and your audio equipment), you should definitely take some acoustic measures. Consider how many hours you spend using the room for this purpose! Room acoustics is definitely not beginner-friendly if you want it to work effectively. There is a lot of literature available, but without measurement technology and thorough planning, successful results are more than just a matter of luck.

... and I believe also by @Mellina and @Solveigh – but for a comparable house size, if I remember correctly, more likely by @blaupuma.

Indeed, only general or rough-scale solutions are readily available off the shelf.

@untergasse43 For acoustic optimization, my focus is not on music but purely on the everyday living comfort. A room with echo and strong reflections is simply very unpleasant. We have a ceiling height of nearly 7 m (23 feet) and it doesn’t feel like a church at all. The music comes from relatively simple hi-fi equipment from Atoll, Naim, Triangle, JM Lab. High-end used to matter, but that time is over.

In our home theater, we have the Knauf Cleaneo panels. They are also available in a more modern design, like those typically used in offices. We also looked at Lignotrend, but with the low ceiling height of 250cm (8 ft 2 in) in the basement, it felt too oppressive for me. However, in a suitable room, I would definitely lean towards Lignotrend, also because I prefer wood over gypsum.

In any case, it definitely makes sense to consider these options for private buildings as well.

Unfortunately, I can’t provide experiences from before and after installation, since we implemented this directly during construction, and the difference was already very noticeable then.
