What is the humming sound coming from the driver side front wheel well? on 2001 Chevrolet Blazer

When I get up to about 30 mph, I get a humming noise coming from the driver side wheel well. The vehicle steers normally, but the faster you go the louder the noise gets.

Had the same problem and turned out to be the wheel bearing. sound like an old airplane engine? that's what ours did - about $150 to fix depending on if you buy the part yourself or have someone else do it.
