I am working as a Technical Sales engineer in one of Indian leading Acoustic Company. Everyday I receive minimum three calls for the same problems which you stated here. There two types of Sound transfer First is through Air borne like person Voice, speaker, sound horn. Second is through Structures like person knocking the door, neighbour people jumping the floor, elevator noise, etc.
Yours problem comes under second type. This problem in ceiling concrete floor occurs due to lower steel usage and thickness of the concrete.
The exact solution for this problem is to install the acoustic underlayment GETZNER AFM 23 under the Flooring tiles, which is specially designed for this kind of issue. But, it should be done during the construction stage of the building only. It can not be done after construction.
If you use Acoustic panels and ceiling tiles, this products will reduce only the noise transferred though Air borne. So there is no solution reduction of this structural borne noise currently.
Please don't spend your precious money in Acoustic Ceiling tiles or Wall Panels.
While respecting your competence - We have had very good success with the suggestions we made above.
Acoustic panels, glass wool panels, acoustic false ceiling from Saint Gobain/Armstrong are very effective after construction solutions for noise absorption.
