Bioacoustic Characteristic of Male Dolphins Bottle Nose (Tursiops aduncus)

Abstract: Bioacoustic is a knowledge that combines biology and acoustic which usually refer to research on the production of sound, dispersion through an elastic medium, and acceptance in animals, including humans. This research uses the method of the passive acoustic and observing behavior of male dolphins through a bioacoustical approach to see the different patterns and characteristic sounds of bottlenose dolphins in Indonesia. Male dolphins (Tursiops aduncus) are preserved at the Park of Safari Cisarua Bogor in Indonesia. The lowest intensity value found was 28.03 dB and the highest was 32.01 dB. With an average parameter measurable namely salinity by up to 30 ppm and temperature 23 °C with the depth of the pool 4.5 meters. The frequency range of their clicks is at 14.221-15.100 Hz. Dolphins tends to be basic a pool of water in as before eating and dolphins always was sitting on the surface of the pond at the time after eating.
