lawriesv has said some nice things

Wood floor assemblies (including finished flooring, subflooring, and joists under them) tend to dry out with time more than when they were first installed, and shrink (in the cross-grain directions) when drier. This allows movement between the components. Higher dynamic forces (e.g., due to more weight, moving) would cause additional movement of some of the now-looser components (i.e., creaking).

Some better renovations add additional screws to tighten the joints between the components, reducing the creaking.
