[ad#block]The humming you hear is actually the bulb filament vibrating. This is caused by the dimmer switch, but certain bulbs can contribute to the problem. Dimmers work by cutting the power to the bulb on and off at a high frequency. This causes the bulb filament vibrate.
So what are your options?
Try one of the following: Rough Service 130 volt bulbs have heavier supports for the filaments. Consider using fluorescent bulbs that can be dimmed. They will not hum because they do not have traditional filaments. Upgrade your dimmer. Inexpensive dimmers do not have the internal devices to correct this problem. High-end dimmers contain inductor chokes and interference capacitors to smooth out the electricity.

This is a testing tool that is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
This is great to troubleshoot a problem with outlet circuit wiring, is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets
Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency
Lights indicate if wiring is correct and indicator light chart is included
Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect, Very handy and easy to use.
