Abstract
This paper focused on the analysis of underwater intermittent biological noises produced by dolphin, shrimp, seahorse, bubble samples. We analyzed the noise frequency spectrum and calculate sound level pressure for every sample in its frequency distribution. Using stationary test, signal changes in the interval of 0.1 second is observed. Assuming Gaussian distribution, normality trial is investigated. Simulations and examinations are done using MATLAB programs in order to illustrate signal noise behavior to optimize filtering and detection purpose. From this study, all samples exhibit stationary and normality distribution properties, in addition the bubble and shrimp have a higher sound pressure level compare to other samples.
