Mute

{
  "id": "MLC-T-OAG-004391",
  "term": "Mute",
  "field": "Oil and gas",
  "definition": "To zero out portions of a seismic record that are dominated by noise or unwanted coherent events, preventing them from contaminating later processing steps. A top mute is applied to remove the direct arrival and refractions that precede the reflection data, while a bottom mute can remove noise at late times and large offsets. The mute function is defined by a polygon of time and offset coordinates applied to a seismic gather.",
