Understanding Acoustic Emission Testing- Reading 1 Part B-A

location, source, n- any of several methods of evaluating AE data to
determine the position on the structure from which the AE originated. Several
approaches to source location are used, including zone location, computed
location, and continuous location.
location, zone, n- any of several techniques for determining the general
region of an acoustic emission source (for example, total AE counts, energy,
hits, and so forth).
NOTE 8- Several approaches to zone location are used, including
independent channel zone location, first hit zone location, and arrival
sequence zone location.
(a) independent channel zone location, n- a zone location technique that
compares the gross amount of activity from each channel.
(b) first-hit zone location, n- a zone location technique that compares only
activity from the channel first detecting the AE event.
(c) arrival sequence zone location, n- a zone location technique that
compares the order of arrival among sensors.
