Acoustic Strength Comparison between Green Turtle and Fish Using Echo Sounder

Acoustic power measurement using dual frequency echo sounder operated 200 kHz were conducted on Green Turtle and fish. The echo signal from Sensitivity Time Control (STC) output was digitized at a sampling rate 1MHz using multifunction DAQ device (Measurement Computing USB1208HS). The animal's...
