One possibility could be a bad wheel bearing.
If a car has a loud humming noise when accelerating, it could be that the air filter is missing. The air filter housing might also be loose. A loud humming noise can also be a signal that there is something wrong with the alternator belt or the fan belt.
it could be your tires on the pavement.
No. The loud humming noise could be a wheel bearing going bad and it could damage the ABS sensor if allowed to continue.
There could be a humming noise from the engine of a 2002 Toyota Corolla because of low oil or a fouled spark plug. It can also indicate a more serious problem.

Certain types of tires may cause a brief humming noise after your initial acceleration. The transmission may also cause a brief humming noise.
turn the key if u heaar a humming noise that means your fuel pump is fine but i would say it has to do with your fuel pump or something in that system

Could be many things but a front wheel bearing/hub assembly going bad comes to mind. Scalloped worn tires can give you a humming noise also.
Your engine might make a humming noise near the alternator after you shut it down because the fan is still running or because the fuel pump is shutting down. Another cause for the humming noise could be the AC motor turning off.
There can be a slight humming noise while driving a neon. This sound could come purely from the engine to indicate that it is running.
