Why is my Audi 80 making a strange humming noise while driving?

I recently purchased a used Audi 80 and have noticed a strange humming noise coming from the engine while driving. It seems to get louder with acceleration but then stops when I come to a stop. Any ideas on what could be causing this? Thanks in advance!

It's possible that there is an issue with your wheel bearings. This could cause a humming noise that gets louder with acceleration. I suggest bringing your car to a mechanic for a proper diagnosis and repair.
