The sound to which you refer is typically produced in the ballast. A noisy ballast is often an indicator that ballast is not doing well.
The ballast is a special purpose transformer, and inside the transformer are coils of wire that are around an iron core. The core is typically a stack of stamped plates made of mild steel that have been riveted or otherwise connected together to provide the necessary mass. When the plates are not tightly bound together, they can move slightly under the changing magnetic field and produce a humming sound that can be quite loud. When that happens, the ballast is about to fail.

Are fluorescent lights better?
Fluorescent lights are energy-efficient and produce more light than incandescent bulbs, making them a popular choice for general lighting.

LED lights are another energy-efficient option that can provide similar brightness without the mercury content or flickering issues of fluorescent lights.

Why do light buzz?
most likely from all of the electricity flowing through them. Incandescent lights do not buzz. Fluorescent fixtures with a non electronic ballast can develop a buzzing or humming noise. The ballast has a wire coiled around an iron laminated core. As the ballast ages the laminations start to separate and the alternating current going through the ballast makes the iron layers vibrate (hitting each other) causing the hum or buzz sound.
