Abstract:
The application of passive acoustic in marine can be used to ease
the researcher for detecting the moving and static object in the water. The
Fast Fourier Transform and wavelet is applied to the signal system in
order to detect the noise and signal perform by object detected. The
experimental results present the data got from koi fish and gourami fish
in the plastic container which dimension is diameter 20cm and height
10cm. The data shows that the object can produce 13 sound patterns
which koi fish has -15,66 dB in sound intensity while gourami fish has -
18,71 dB.
