With modern LED lighting, buzzing or humming is often caused by a mismatch between the dimmer and the lamps, especially near the low end of the dimming range. Sometimes the fix is a better lamp, a different dimmer, or adjusting the dimmer settings. If the noise is persistent, new, hot or unstable, it deserves a proper check.
