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.

Bad speed sensors can cause the car to hesitate when accelerating at speeds below 20 mph. The blockage of the air filters can also cause the car to hesitate when accelerating at speeds below 20 mph.
My car is accelerating at 10 miles per hour per hour.
bad wheel bearings
You may be hearing the coolant passing thru the heater core with an air pocket trapped in there.
when you turn your key and you only hear humming noise, the problem will most likely be that the starter is not engaging the fly wheel, its turning but is not sliding forward to do its job. have the starter check.
If it sounds like its coming from inside the car its probably the fuel pump if not its kind of hard to say.
The humming is a series of explosions in the engine happenning very quickly. Could also be an electric fuel pump if the vehicle is equipped with one.
a humming noise is usually related to the fuel pump about to go. or u just have a really loud fuel pump and everything is fine.
