Why do transformers hum?
Transformers hum due to the vibrations caused by the alternating magnetic fields in the transformer core. These magnetic fields are constantly changing direction as the alternating current passes through the transformer, causing the core to expand and contract slightly. This expansion and contraction create mechanical vibrations that produce the humming sound. The frequency of the hum is typically related to the frequency of the alternating current passing through the transformer. **
What is a hum voltage?
A hum voltage refers to the presence of unwanted electrical noise or interference in an audio signal. This interference can manifest as a low-frequency hum or buzz in the audio, which can be caused by various factors such as ground loops, electromagnetic interference, or improper equipment grounding. Hum voltage can degrade the quality of the audio signal and is often undesirable in professional audio applications. Measures such as proper grounding, shielding, and using balanced audio connections can help reduce or eliminate hum voltage in audio systems. **
