Rotate the tires and check the wear on the pads when you do. Clean the whole area once its open with a good cleaner and wash it down good. If all the pads are good and the rotation of the tires doesnt help try and isolate the side its on. Check the rotor and put in a break quiet, then recheck. If this still has an issue you can pull the side apart and then check the bearings. Put it back together and recheck. If its still there I would take it to a shop if your concerned.

MAKE CAR MAKES THE SAME NOISE AND REPLACING THE PVC VALVE FIXED THE PROBLEM
could be your wheel bearings
Not much info to go on but, it could be a wheel bearing going bad.
it does that because it has a generator which makes the engine makes these sounds
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 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.
Sounds like you have an older 4 cylinder car. I had a Pontiac 2000 4 cylinder that did that.
Possibly a wheel bearing
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?
could be fuel pump on the right side of car
as far as the humming noise and the grinding noise it sounds like your power steering pump is either out of fluid or gone bad completely. as for the muffler? ?MAYBE? the strain from the bad power steering pump is overworking the engine causing it to make noise? answer definetly a bad steering pump as for muffler, the sound can be transfred and magnified on a car, replace steering pump before bothering about the muffler sound may be gone
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.
