Measuring the off-axis angle and the rotational movements of phonating sperm whales using a single hydrophone
International audience The common use of the bent-horn model of the sperm whale sound generator describes sperm whale clicks as the pulse series {p0, p1, p2, p3, . . . }. Clicks, however, deviate from this standard when recorded using off-axis hydrophones. The existence of additional pulses within t...
