types of trains can be used to investigate the general echolocation behavior. For
example, the automatic measurement of inter-click interval (ICI) is greatly underestimated in overlapped clicks, but apart from that, other spectral and time parameters
can be extracted using such clicks sequences without any inaccurate result.
For a general quantitative approach, some acoustical parameters can be automatically extracted: peak frequency, 3 dB bandwidth, 10 dB bandwidth, inter-click
interval (ICI), sound pressure level (peak to peak), root mean square amplitude
(rms) and number of clicks in train.
Fig. 5.6 Click trains. (a) Clicks can be aurally assigned to one vocalizing animal and do not show
any other clicks belonging to a different train and (b) Overlapped clicks produced by more than
one animal
