  "term": "Hash noise",
  "field": "Industrial and trades",
  "definition": "A type of broadband electrical noise characterized by its harsh, raspy sound when demodulated, originating from intermittent, high-current electrical discharges. It is produced by sources such as the sparking commutators of DC motors, faulty thermostats, or loose electrical connections that create a rapid series of small arcs. The noise spectrum is wide and contains many random frequencies, making it particularly disruptive to AM radio reception and other sensitive analog communication systems.",
