Male sperm whale acoustic behavior observed from multipaths at a single hydrophone
International audience Sperm whales generate transient sounds (clicks) when foraging. These clicks have been described as echolocation sounds, a result of having measured the source level and the directionality of these signals and having extrapolated results from biosonar tests made on some small o...
