Electrical Mean Noise Sound Sound waves Waves

AI Thread Summary

Electrical noise in cables, transformers, and stations primarily arises from mechanical vibrations caused by electromagnetic forces, leading to audible sound waves like humming or buzzing. This phenomenon, often referred to as "mains hum," can be attributed to the interaction of alternating current with the physical components of electrical systems. Factors such as magnetic fields, resonance, and mechanical stress contribute to the generation of these sounds. To effectively search for more information on this topic, using terms like "electrical hum," "transformer noise," or "electromagnetic sound waves" may yield better results. Understanding the sources and mechanisms of electrical noise can aid in mitigating its impact in various applications.

Hello physicsforums. What causes noise in electrical cables and/or transformers and/or electrical stations ? By noise I mean mechanical sound waves like bzzzzzzzz, not signal noise. And what is the proper way to search in google for this, I could not find a wikipedia article on this.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
