I think something is amiss. I have never had a dimmer hum. Check wiring and make sure you are not consuming more current than their rated current capability.

Loud Dimmer Switches
I just installed 2 dimmer switches from Home Depot in a dedicated room. They give off a humming sound. These dimmers have 5 settings which are touch controlled and they cost $29 each. Are some types of dimmers better than others not giving off a hum. Both dimmers are on dedicated lines.
Thanks
