| Summary: | This project is about developing a hydrophone system for the purpose of autonomous
undelWater vehicle CAVY) application. AUV is an underwater vehicle which travels
underwater. Hydrophone is an underwater microphone which with the help of pressure
impulses of acoustic waves converts them into electrical signals which in further are used for
communication. It was designed to be used underwater for recording or listening to
underwater sound. Hydrophone needs an audio recorder to analyze the spectrographic
analysis, without necessary to carry the computer into hostile marine environment.
Spectrogram is used to simulate the sound signal of underwater sounds. Spectrogram is a plot
of the frequency component such an audio signal as function of time. In this spectrogram
program, digital audio recording are analyzed to produce a plot of frequency versus time, with
harmonic intensity represented by a variable color scale. Hydrophone acts as a medium to
study of the underwater acoustics which is a propagation of sound in water and the interaction
of the mechanical waves that constitute sound with the water and its boundaries. Then, the
hydrophone system is tested by recording the undelWater sound signals at the location to make
sure that the system in good condition. |
