Does anyone recognize these ceiling panels?

They are installed in the ceiling of a small bedroom in a house from 1893, which has been renovated in stages before I bought it. The feeling in the room is that the ceiling panels somehow dampen sound.

Someone who has seen the ceiling guessed "tretex," another said "absorbent panels." The material feels a bit "porous."

Since I want to remove the asbestos from the house, I'm considering. Could these ceiling panels contain asbestos?

Should I take a sample, or can I simply leave them in place regardless of whether they contain asbestos or not? Feels important considering that children sleep in the room.

Grateful for good advice! Ceiling panels in a small bedroom, possibly sound-absorbing with a porous texture. Concerns about potential asbestos content from renovation. Porous ceiling panels in an old house, possibly sound-absorbing or containing asbestos, with visible seams and a smooth surface.
 
Addendum:

The boards don't feel particularly porous, as I initially thought. When tapped, they are quite hard, and you have to press fairly hard to make them "give" slightly under your finger. That is, you sense a tendency that the material might be a little porous. I don't know, maybe the surface is a bit harder due to the paint on the outside, but definitely not a very porous material in the board. It sounds roughly like tapping on a hard wooden board. However, the surface has a certain texture. Not completely smooth.

some form of huntonit. fiberboard
 
And it is? :)
I've never even heard the word...

Should it be torn off or is it fine where it is?
Probably nice old pärlspont underneath, but unsure if I dare to tear into the boards, in case they might contain asbestos.
Do you have any idea SBH?
 
Googled a bit about huntonit.
In most pictures, it looks like huntonit has a type of "grain structure," stripes like in a regular wooden plank.
That's not how my ceiling looks. It appears more slightly "bumpy." And the panels make the room somewhat sound-dampening.
As if the panels could be some type of absorption board.
Does huntonit have such an effect?
And does tretex or huntonit contain asbestos?
Or is it just a matter of tearing it down?

träfiberskiva. if you like the boards, then keep them.
there is a risk that the material behind is not very nice.

That's tretex. There's no asbestos in them!

Have seen those before and it's some form of "finished ceiling" of tretex type. No problem keeping them.

No idea what it could be, but I'll throw in a little thought that might be worth considering. :)

I might be wrong, but isn't asbestos safest as long as it stays in place? That is, no dangerous asbestos fibers are released as long as you don't disturb the material? As far as I understand, the danger in asbestos is the small fibers that fly around when you tear and saw into it, and which you then inhale. Of course, IF there is asbestos in interior walls and ceilings, some might be released if you were to drill to hang pictures or lamps, but is there really asbestos in wall/ceiling coverings indoors? Isn't it just in facade panels, ventilation pipes, and old brake pads that asbestos was used, kind of...?

Anyway, think ahead (which you are doing with this thread ;) ) so you don't create a lot of unnecessary work. Asbestos is not to be played with, but I THINK your kids aren't harmed by being in a room in a house where there's asbestos in the walls, provided they don't tear down the walls.... :D

They are some form of tretex boards. Try pressing in a thumbtack or a pin. It should go in easily with hand power if it's tretex. The boards provide good soundproofing in the room, so if they are not too ugly, there is a point in keeping them.

There is no danger in tearing them down. It will create a lot of dust, but it's not hazardous dust.

Most likely, it is a regular ceiling tile with a slightly bumpy texture, and it could be made from a thicker form of masonite or wood fiber.
And it's probably absolutely not asbestos in them.
If it had been a tractor garage with ceiling tiles, there would probably have been a greater risk of asbestos tiles.

Tretex and Masonit are probably old companies that manufactured different types of wood-based boards....

I have similar ceiling panels in my house, and it is a form of fiberboard with a more durable surface layer of paint.

So it is a slightly harder tretex board with paint on it.

And you don't need to worry about asbestos! But if you tear it down anyway, make sure to use dust protection because they create a lot of dust! When you break them.

A quick question, why so worried about asbestos in everything?

tretex and huntonit are materials that differ from each other. if the ceiling were made of tretex, one could cut these sheets with a utility knife.
