Consider replacing it with an electronic ballast, which is quieter. All ballasts—fluorescent light fixtures' controlling mechanism—will have a low hum, but only if you get close to it.  — learn how to test ballast for fluorescent lights using visual inspection, continuity, voltage, current draw, capacitor, starter, igniter, lamp socket and power supply tests.  — magnetic ballasts have metal plates that vibrate as well as an intense electromagnetic field that can generate a buzzing noise. Find out how to tighten the bulb, replace the ballast, update the dimmer, or contact an electrician if needed.  — learn the common causes and solutions for a light fixture making buzzing noise. Adjusting the fluorescent light should fix the connection problem.  — the first step is to check that the ballast mounting is screwed tight.
