Link RemovedTransformers hum because their laminations and windings rattle mechanically. This is best known as mechanical hum. This can be caused by several things, including poor construction and poor AC power conditions or both. If your equipment has a noisy transformer, you’ve probably also noticed that it’s intensity varies depending on the time of day, sometimes even the time of month. The reason it varies is due, in large part, to the quality of the AC line voltage and how much DC is on it.
