The information of first arrival time of acoustic emission (AE) signal is very important in event location, event identification and source mechanism analysis. Manual picks are time consuming and sometimes subjective. Several approaches are used in practice. New first arrival automatic determination technique of acoustic emission signals in thin metal plates is presented. Based on Akaike information criterion (AIC) relation, proposed algorithm of the first arrival detection uses the specific characteristic function, which is sensitive to change of frequency in contrast to others such as envelope of the signal. The approach was tested on real AE data recorded by a four-channel recording system. The results were compared to manual picks as well as to other AIC approach. It is shown that our two step AIC picker is a reliable tool to identify the arrival time for AE signals.
