Q. What is an LED music bulb?

Answer

The pulsing of LEDs may be heard through speakers. Ground loops, subpar, RF interference, and unshielded cables are the typical culprits in such cases. The speaker may be buzzing for one of three major reasons: a ground loop, radio frequency interference, or unshielded wiring. When many devices in various places use the same AC (alternating current) circuit, a ground loop is created. In a typical circuit, all components share a common ground connection, which also forms a closed loop. Radio frequency interference is another common reason for buzzing speakers. This happens when a radio frequency is emitted from a nearby appliance, as the name implies.
