The humming sound is the fuel pump. this is normal the sound is the air compressor for the ELC (Electroinc level control) it pumps air into the rear struts the level the car out when you turn on the key.
The caliper may be hanging and causing the humming sound. I cant type the sound out but it mine made a humming noise as the wheels turned. If I pressed the brakes hard and quickly let go it would stop. I just replaced rotors and brake pads and it is back to normal now.
Bad wheel bearing or there is a problem with the tire itself.
The metal band holding the exhaust is broken.
Yes a humming out back could be a fuel pump failing. I have gone through 2 in my 1993 Century - 150 k miles - They have to drain and drop the tank to repair
on cars that run with fuel injection it would be the fuel pump, or high performance cars that use electric fuel pumps.

Humming birds are among the smallest birds. They are known as hummingbirds because of the humming sound created by their beating wings, which sometimes sounds like bees or other insects. To conserve energy while they sleep or when food is scarce, they have the ability to go into a hibernation-like state (torpor) where their metabolic rate is slowed to 1/15th of its normal rate.When the nights get colder, their body temperature can drop significantly and thus slow down their heart and breathing rate, thus burning much less energy overnight. As the day heats back up, the hummingbird's body temperature will come back up and they resume their normal activitey.That's why humming bird hums to conserve their energy
