Trained listeners distinguish explosions from earthquakes by audified seismic data

Evidence

Audification is the direct translation of a data waveform into sounds. This process requires that the transformation is made along the human audible spectrum with possibilities to increase or decrease the time. One example is represented by seismic data: in this way is possible to distinguish the variations of strata complexity in oil exploration or in earthquake events. In one experiment listeners were able to separate more than 90 % of the underground explosions from earthquake events (Speeth 1961). Some waves when transformed in a sonic format can be easily distinguished from the background noise, and auditory expectation can be produced rapidly; for instance, 24 h of data can be represented in 5 min of acoustic output. — Almo Farina, Soundscape Ecology, 2434
