Modeling, estimation and classification of sounds generated by marine mammals

Modeling, estimation and classification of sounds generated by marine mammals

Dolphins have a rich vocal repertoire that has been categorized into three classes: 1) broadband, short-duration clicks, called sonar clicks, used in echolocation for orientation, perception, and navigation; 2) wideband pulsed sounds, called burst pulses, used in social contexts and 3) narrowband frequency-modulated whistles also used in social contexts. The research carried out by Dr. Greco is devoted to the analysis and modeling of echolocation signals emitted by the Tursiops Truncatus (bottlenose dolphin) living in the Tuscany Archipelago Park in both audio and ultrasonic bands. The research activity has been partially found by the European Project INTERREG IIIA and carried out cooperating with the CE.TU.S Center (Viareggio, Italy)
