2001 Corolla/Prizm - have a humming sound from left front wheel area. Starts
at 30 mph, stops at 60 mph. Gets louder in right turns at speed, gets quiet
in left turns. Stayed the same when new tires and brakes were installed. Has
been there for a year, only recently getting worse. CV joint? Wheel bearing?

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.

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.

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