Bioacoustic is 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 using passive acoustic method and behavior observing of male dolphins by doing approach science of the passive acoustic (bioacoustics) is see the difference patterns and a characteristic sound of the porpoise. Dolphins male (Tursiops aduncus) preserved in park of safari indonesia cisarua bogor, having value intensity lowest of 28.03dB and the highest is of 32,01dB. With an average parameter measurable namely salinity up to 30% and temperature 23°C with the depth of the pool 4,5meters. Range the frequency of sounds click with the highest intensity of 32,01dB with a clicking sound after food in first day to 2 which is found in range frequency namely 14.000-16.000Hz. Range the frequency of sounds click dolphins male (tursiop aduncus) in park of safari with frequency of 14.221-15.100Hz. There is a difference intensity voting against treatment before and after eating by using the pool the same study. Value intensity highest obtained at the sound of after food in second day with the intensity 32, 01dB and value of the lowest intensity of are in before a meal is first day. Dolphins tends to be basic a pool of sea water in as before eating and dolphins always was sitting on the surface of the pond at the time after eating .

In the world fisheries own with the methods acoustic passive applied to monitor marine mammals, and biota other on the sea . Signals obtained from recording sound marine mammals very weak that calls for amplification and difficult to determine of which the direction that suarara. Passive is sound derived from animals target . The concept of acoustic passive conducted in marine mammals is to detect a sound when mammals it is in the area measurements in environment scope of the tape recorder. The measurement of is done with use software and also with listen.A method of acoustic passive also used odibidang military service in the development of security system of attackers under water in the estuari by doing recording sound which is raised from diving .
Marine mammals hearing in is measured in the subject living with use audiometer behavior or technique elektrofisiologi . For species does not learn from vivo audiometer. With some characteristic of hearing can be is predicted based on the frequency of the results of the production of sound done on the observation the characteristic sounds good is do or not have response behavior in trained animals ; or morphological hearing , including the trait of biomechanics from the basilar and characteristic of other sounds . A little bit too known the sound has type yelping (burst), characteristic of spectral, temporal, and amplitude a shrill sound pulse of type the sound of a click very few explored. As for early description in literature that most of it that is worth qualitative, that reflects interpretation hearing subjective and classification hearing in humans [7-10].
The sound of a click generally used for the purpose of echolocation , while the sound of a whistle ledakan-berdenyut and played a major role in internal communication and across group . A whistle that continues indefinitely, giving signals frequency , with various wide emissions of 800Hz and 28.5KHz  often there are components harmonic . A dolphin start interaction with the provision of signals, with information , in tape a given frequency. The signal source then
relies on a source of to hear and react to the sound . In hearing to
dolphins ranged from about 50 Hz-150KHz, with the variation of
additional among .
For every years, researchers have demonstrated the
advantages of hydrophones Single Mode Fiber (SMF) as a
potential alternative to the voice navigation and the beginning
of the technology/sound navigation and ranging (SONAR).
Bioacoustic not be separated from the use of hydrophones as
lat voice recorder where the acoustic pressure is recorded on
hydrophone is a source of pressure disturbance at sea (ΔP)
relative to the pressure of the ocean in the background on the
recording medium depth sea water. Excess sound pressure at
sea are usually worth a small (~10-2 Pa), and it has become
the standard in the sea in the literature to show the acoustic
sound pressure in the list of the decibel scale (dB) relative to the
reference pressure (Po) of 1μPa , In addition, the convention
to use 1m as a reference distance (ro), namely when calculating
the acoustic pressure from the source of the sound.
Bioacoustic is the knowledge that combines biological and
acoustics which usually refer to research on the production of
sound, dispersion through an elastic medium, and acceptance
in animals, including humans. This involves neurophysiology
and anatomy for the production and detection sound, as well
as the relations of acoustic signals with medium dispersinya.
Findings in this area give evidence for us of the evolution
of acoustic mechanism, and from there, evolution animals
who use them [14,15]. But because the science of acoustics
grown very much to dolphins, researchers formerly had been
exercising records and analysis vocalization . Bioacoustic
research is needed to know language communication (acoustic
communication) in mammals. Bioacoustic be separated from
the use of hydrophone as lat voice recorder where pressures
acoustics recorded on hidrofon is the source of the disorder
pressure on the (ΔP) relatively on the background the recording
in the medium sea water. This study aims to analyse and
distinguishing characteristics the sound of a click dolphins male
bottle nose (Tursiops aduncus) in quarantine pool , by using the
method bioacoustic and see behavior male dolphins bottle nose
(Tursiops aduncus) .
