There are a half dozen ways to silence a squeaky floor. Nobody does them because it's an expense and hassle and they don't mind the noise. The more difficult problem, reverberation and sound travel, is really a simple acoustics problem.

But if a tenant prefers wood floor, you can install sound-deadening insulation between the subfloor and finished floor, or subfloor and lower ceiling.
