What Typically Causes Phono Hum? Steve Hoffman Music Forums
The typical symptoms of DC offset are an audible buzzing or hum from the audio equipment chassis. It’s important to note that DC offset-induced buzzing will not emanate from the loud speakers. Specifically, it will be the power transformer inside the equipment that will be buzzing. In most instances, it will only come from the equipment with large toroidal transformers, like large power amplifiers. The buzzing will …... The transformer core or the windings are probably vibrating and causing most of the noise. At high enough power levels the iron core itself actually stretches and contracts as well causing vibration.

  • It's a fact of life that an electronic transformer will make a buzzing noise. The 60Hz electrical current passing through it causes it to flex slightly and vibrate at that frequency, a phenomenon scientists call "magnetostriction."
  • Ground loop interference problem is a consequence of this. Always when operating with grounding issues remember that there is no absolute ground . There is a certain amount of resistance to electrical current between all grounding points.
  • There are two major sources for transformer noise: 1. By far, the major cause of transformer noise is Magnetostriction. Magnetostriction is the random movement of individual sheets within the stacked core.
