Why does wheel bearing noise get louder with speed?
As the wheel rotates faster, extra load and friction inside a worn bearing create more noise. This is why the sound often increases steadily with road speed.

Wheel Bearing Noise When Speeding Up
A wheel bearing often becomes noisier as speed increases. The sound is usually a humming, droning or grinding noise that gets louder the faster you drive.
