Abstract:

This study aim at developing low cost underwater navigation system suitable for shallow water environment. Spectral Plus 5.0 software running on two computers was used for generating and measuring sound pressure in open air and shallow water (350 mm deep) using a pair of piezocrystals plates (2 cm diameter) from old wristwatch buzzer. The best frequency response was found to be at 4.5 kHz without amplification. The setup was able to respond to obstacles placed in between them when spaced at experimental distance of 30 cm and 60 cm. Obstacles used are plywood, asbestos, PVC plastic and Iron sheet. It was found that the responses are material dependent.
