A typical steel-stud partition assembly rates around STC 42. That lets loud speech through, so it is often worth upgrading between bedrooms, offices and meeting rooms.
Most effective upgrade
Use 25-gauge studs (which flex and isolate better than heavier gauges), double drywall and full-height construction to the deck.
Acoustic panels on the surface add only 1–3 STC points. They are for the sound inside the room. See STC vs NRC and flanking paths.
