Continued Investigation of the Acoustics of Marine Sediments Using Impedance Tube and Acoustic Resonator Techniques
نویسنده
چکیده
The main goal of this project is to increase our understanding of sound propagation in ocean bottom sediments, including ocean bottom multiphase material such as gas-bearing sediments and seagrass, which in turn benefits buried object detection, sonar operation and acoustic communications in shallow water. Another goal for the out years is to develop the proposed research apparatus into an operational system for in situ classification of ocean bottoms for Naval fleet operations.

Investigation of the Acoustics of Marine Sediments Using an Impedance Tube
The primary objective is to obtain experimental measurements of the plane wave reflection coefficients from laboratory and in situ sediments using impedance tube [1] and acoustic resonator tube [2, 3] methods, in the frequency range of approximately 300 Hz to tens of kHz. This approach will also yield measurements of the acoustic impedance, sediment sound speed, attenuation, and complex density...

متن کاملDetermination of sediments diameter using acoustic waves
The use of acoustic waves in researches related to sea water is of most importance among scientists recently. Since these waves are the only waves, transmitted in water with lowest attenuation and high speed, they can be used in many scientific fields. The main goal of this research is to better understand the physics and mechanisms of sound-seabed interaction, including acoustic penetration, p...
متن کاملTechnology Development for Electromechanical Acoustic Liners
This paper presents two key technology components required for the development of a self-powered, wireless, active acoustic liner system. The envisioned system consists of a tunable Helmholtz resonator for acoustic impedance boundary condition modification and an acoustic energy reclamation module as a system power supply. The common electroacoustic element for both of these components is an el...
