"jip rock", I think you are mixing terms.
Gyp is an acronym for gypsum which is drywall.
Rock is an acronym for for rock lath, one type of the base sheet for
interior hard wall, plaster.

There is a product, applied to framing, that is manufactured by the drywall industry which is a sound absorption.
There are also several "systems" which can be employed to affect sound transfer, both on the producing as well as the transferred side.

If you will elaborate your particular condition, it will be easier to offer some solutions for you to consider.
