چکیده

This papa deals with exploring the availability and reliability of subtraction techniques, based on spectrally dense signals such as Maximan Length Sequences, in evaluating the echo reduction losses of samples of interest in undawater acoustics. These techniques, first employed in air acoustics, were adapted to the undawater environment. Experimental results how how a measurement can be accomplished and the limitations produced by the actual available combination ofsoft, hardware and tank and sample dimensions.

Effect of porosity on the characteristics of underwater acoustic sound absorbers using theoretical models‎

Porous materials have good acoustic damping characteristics over a wide frequency range. As for sound waves, many small-scale pores in the coating materials can convert underwater-coating to rough surfaces. The main property of porous absorbents is their resistance against incident sound wave that leads to damping effect. From a physical point of view, damping occurs due to friction between flu...

Evaluation of Acoustic Emission Inspection of Oil Tank Floor via Tank Bottom Plates Thickness Measurement

This paper deals with an inspection of defects including corrosion and leakage by Acoustic Emission (AE) in an oil tank floor. In contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in AE method in order to inspection. In this research AE investigation and AE source location is presented in detail. The resul...

Design, manufacture and the evaluation of Fluvial Acoustic Tomography System (FATS)

Underwater Acoustic Tomography (AT) system transmits acoustic waves into the water. The AT systems continuously measure the physical characteristics of the flow in rivers, seas and the oceans. The AT systems are synchronized via a GPS clock connectied to the satellites. Hence, the systems transmit the acoustic waves at the same time. The systems record the arrival time of acoustic waves. After ...
