Electrical noise ( I mean sound waves )

Click For Summary
SUMMARY

The discussion centers on the causes of mechanical sound waves, referred to as electrical noise, in electrical cables, transformers, and electrical stations. Participants clarify that this noise, often described as a buzzing sound, is primarily due to electromagnetic vibrations and mechanical resonances within the equipment. The conversation also highlights the difficulty in finding comprehensive resources on this topic, with a suggestion to refer to the Wikipedia article on "Mains hum" for further information.

PREREQUISITES
  • Understanding of electromagnetic theory
  • Familiarity with transformer operation
  • Knowledge of sound wave propagation
  • Basic principles of electrical engineering
NEXT STEPS
  • Research the principles of electromagnetic vibrations in electrical systems
  • Explore the design and operation of transformers
  • Investigate sound wave propagation in electrical environments
  • Learn about noise reduction techniques in electrical engineering
USEFUL FOR

Electrical engineers, physics students, and professionals involved in the design and maintenance of electrical systems who are interested in understanding and mitigating mechanical sound waves in electrical equipment.

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.
