Soundproofing / Acoustic Optimization

LoL, well the best suggestions are there, furniture, flowers, etc.

If it should be with USB, a projector on the ceiling with a screen etc. also works (additionally).

... Pictures on stretcher frames, if necessary insulated from the back.
Window curtains... !

Animal skins... pigskin, fox pelt... also look good!

Noise cancelling headphones?
Cover with Flokati?

Good topic.

What do you currently have on the ceiling?

We are building an approximately 55m2 living and dining area with an open ceiling up to the ridge. (Ceiling height 5.20 m)

Originally, it was planned to plaster the ceiling and then put smooth painter’s fleece on it.

But now I have strong doubts and we are now getting a white wooden ceiling with this tongue and groove system (wooden boards).

We currently have this system in our rented apartment on the ceiling as well.
Also open up to the ridge but (only) 3.50 m
And here we have no problems at all.

But now I have serious doubts and now we are getting a white wooden ceiling with this tongue and groove system (wooden boards).

What acoustic builder's benefit do you expect from this? You are usually quite a fan of the Hauscompagnie buildings, I recall an example picture with an acoustic ceiling above the dining room.
