Is it possible to stick acoustic foam on movable partition walls and will it be of any use?
Actually, the essence of the issue is in the topic. Thanks in advance for your reply.
It is possible to do so, but the efficiency will be low. The meaning of foam rubber is to acoustically absorb sound and prevent sound reflection from walls. If you move it or bend it somehow, then its meaning is lost, since the structure begins to change or even collapse. Also, in the attachment points, if there is no proper density with the door frame, the sound will still pass. The noise immunity of doorways and the doors themselves is done differently than walls.
You can stick it on, who forbids ... And about the sense - what sense do you expect? Make the partition softer? Well, it will be a little softer ..
Not enough, you cannot ensure the tightness of the joints of such walls
