Answer Humming noise from front endI just got my car fixed with the same problem and it was the wheel bearing and it is gone. Was it a fwd car?
Raise the hood and have a helper start the car while you listen. Check around the top of the engine to find the humming.
That could be any variety of things, of a combination of them, it would be best if you take your car to a trusted mechanic.
Possibly the 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.

A humming noise on a 1999 Park Avenue is caused by bad wheel bearings. When bearings are loose or worn they will create a loud humming noise that will get louder and louder as the car accelerates.
Possibly worn wheel bearings can create a humming or groaning sound.
it does that because it has a generator which makes the engine makes these sounds
cold engine
Bad wheel bearing.
i would first balence the tires then try replacing the wheel bearings if the noise is coming from a specific area on the car In example left front, right front etc.
