Percolation | Theoretical term relating to the process of transmission by which sound becomes trapped in geological structures. |
Sonic sedimentation | Process by which sonic phenomena are laid down in strata within sedimentary rock. |
Crystalline induction | Electromagnetic sonic effects found in quartz and other crystalline forms (theoretical) |
Sonic seeding | The active process of surface absorption that precedes percolation. The full process appears to be Seeding > Percolation > Imprinting > Earth Trauma > Release, though this remains to be empirically proven. |
‘Sounding Space’ | A field site in which geological sonic phenomena may be detected. |
Earth Trauma | Historic incident in which the geology of a sounding space has been altered, allowing for the emergence of sonic phenomena. (ie: Mining, earthquake, landslip) |
Imprinting 'Hot Spot' | Post-percolatory capture of sound within subterranean strata. A focused, mainly localised sonic vent |
Igneous response | Distinctive bass-tonal effects, detected in igneous (volcanic) areas. |
Sedimentary response | Distinctive mid-tonal effects, detected in sedimentary (alluvial) areas. |
Metamorphic response | Distinctive vari-tonal effects, detected in areas where geology has been shaped by pressure, or glacial erosion. |
Sonic Porosity | Suitability of geological conditions for seeding, percolation, imprinting and release of sonic phenomena. |
Conversational | Phenomena pertaining to emissions of the human voice. |
Melodic event | Phenomena pertaining to emissions of music or harmony. |
Ambient event | Phenomena pertaining to emissions of natural sound. |
Proto-historic event | Phenomena pertaining to echo-type replay of specific historic events. |
