Does a light bulb give off sound?
Generally, incandescent light bulbs tend to be fairly quiet. Usually, the only time you can expect them to make noise is if you’re using a dimmer.

Why do light bulbs make a popping sound?
The tungsten in the filament provides a fair amount of resistance to the electricity that’s traveling through it, and it’s this friction that causes it to glow. However, all that resistance puts a lot of wear and tear on the filament over time, and when this tightly-stretched wire breaks, it makes that familiar pop.
Why is my light bulb shaking?
Contact problems, faulty wiring connections, worn-out receptacles, or a bad filament can all cause flickering. Often, these problems occur as the light bulb ages. They could also happen as the result of wear-and-tear, improper voltage, or bad wiring inside the fixture.
