Cause of wood was a living thing; it changes as it ages due to reactions to temperature and moisture in the air. Floors squeak due to uneven sub-floors, openings dilating between the planks, and damage or gouges. Also, nails can become loose and hardwood flooring planks can become uneven and loud.
Sub-floors may become uneven over time and that must be remedied first, or else any new floor you put in could get warped and become squeaky extremely quickly. Try and work out why the hardwood flooring has become loud and work on the difficulty from that angle. Remedying a difficulty means fixing and investigating why it changed into a problem in the first instance. Virtually all homes have squeaky wooden flooring, particularly old homes.

Evening out and re-enforcing the Floorboards will ease any squeaks. Unless you have got a family of mice living under your floors, that is.
