It sounds like your serpentine belt may be worn or loose. This can cause a humming noise when your engine is running. I recommend having a mechanic check and replace the belt if necessary.

Check your tires for any signs of wear or bulging. A bad tire can also cause a humming noise while driving. If you notice any issues with your tires, have them replaced as soon as possible.

I had a similar issue with my Audi A3 and it turned out to be a faulty wheel bearing. Have a mechanic check your wheel bearings for any signs of wear or damage.
