  "term": "Noise",
  "field": "Environment",
  "definition": "1. Inherent variability that the model does not characterize (see definition for variability).\n\n2. Product-level or product-volume changes occurring during a test that are not related to a leak but may be mistaken for one.\n\n3. Any unwanted signal; a disturbance that is not part of signal from a specified source. In electrical or induced polarization (IP) surveys, noise may result from interference of power lines, motor-generators, atmospheric electrical discharges, etc. See cultural noise.",
