Lower ceiling apt moisture barrier ??

[Avipami]

I've been sporadically searching for answers over several days on whether a vapor barrier/moisture barrier is necessary when installing a gypsum ceiling in an apartment.

This new apartment had a damaged stretched fabric that we thought could be replaced with gypsum for increased sound insulation against the neighbors above.

My inner thought is that a moisture barrier might not be needed in an apartment with a cement/concrete ceiling? But I'm not 100% sure.

Does anyone know?

Just gypsum, no plastic...

Is it regardless with a concrete roof? Old house from the 40s

Is it the same with concrete roofs? Old house from the 40s

Even less because of the concrete roof
