Steel framing tends to be correlated with higher wall mass, which means better sound isolation. The original discussion was about noise in multi-family homes e.g. apartment buildings and high-rises, which tend to be steel beyond a certain height. While there are single-family homes built with steel framing in the US, they are less common; they have some advantages but cost more to build and are more difficult to thermally insulate than wood. Every multi-family high-rise I've lived in used steel construction and drywall and had excellent sound isolation -- I never hear my neighbors and vice versa.
