Humming sound

If the car knew the words, it could sing instead of hum ;-)

Seriously, noises are difficult, if not impossible, to diagnose without hearing them. Common causes of noises that change in amplitude or frequency when turning left or right are wheel bearings and CV joints.

The best way to identify the source of the sound is to have a competent technician go for a road test with you so that you can point out the sound.

I passed on that one! ;)

Check your right rear wheel bearing, more often than not noises that seem to come from the front of the car (especially those that sound like transmission or drivetrain noises) are actually coming from the back and vice versa.

To check the CV joints drive slowly at full lock with the drivers window wound down and if you can hear a clicking noise then that will be the inner front wheel in whichever direction you are turning.

could be, yes.

Sounds like his wife left a battery powered vibe in the glove compartment.
