Available in PDF, EPUB and Kindle. Book excerpt: The electrical and acoustical measurements described in this book are those required to calibrate, test, or evaluate an underwater electroacoustic transducer and to enable one, indirectly, to produce or detect and measure an underwater acoustic signal, usually in terms of its acoustic pressure. These measurements will be referred to collectively as underwater electroacoustic measurements.

Available in PDF, EPUB and Kindle. Book excerpt: A near-field acoustic measurement technique which provides the basis for accurately computing the far-field radiation characteristics of underwater sound transducers is developed, implemented and evaluated. The analysis is based on evaluating a form of the Helmholtz integral which utilizes a Green's function with particular boundary conditions for the solution. That is, the Green's function vanishes over the surface of integration, thereby requiring only knowledge of the near-field acoustic pressure for computing the far-field radiation. An experimental program is conducted to provide corroboration of the near-field technique. Design and construction details of the completely automated near-field measurement system, including the near-field acoustic sensors, the pulsed Amplitude-Phase electronic measurement system, and the Digital Scanner System are presented. Appropriate supporting software, in the form of a digital computer program, is provided for performing the data preparation and final far-field computations. Results of conventional far-field acoustic measurements at various frequencies on four different types of test transducers are presented.

This book was released on 1969 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and construction of the terminal and source transducers, a reciprocal spherical piezoelectric ceramic transducer, and the probe hydrophones that are part of a new USRD measuring facility are described. The facility is used for the calibration of underwater sound transducers in the frequency range 10 to 4000 Hz at hydrostatic pressure to 10,000 psig and controlled temperature from 3 to 45 deg C. It operates on the principle of active-impedance termination in a rigid-walled, water-filled tube.

Download or read book Reciprocity Calibration of an Underwater Transducer by the Delta Z Method written by Raynald Bedard and published by . This book was released on 1987 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for determining the free-field open-circuit voltage sensitivity of a reversible underwater electroacoustic transducer from the difference in its input electrical impedance when loaded by water and air was investigated theoretically and experimentally. An equation for the sensitivity was derived using reciprocal two-port network theory. The theory takes into account the diffraction due to the finite size of the transducer, its finite mechanical impedance, and its free-field radiation impedance in water. An experiment to test the predictions of the theory was performed using a 6 in diameter, hollow, piezoelectric ceramic spherical transducer. The results of the experiment agreed within several dB with standard comparison calibration over the frequency range for which both the electrical impedance and comparison calibration data are considered reliable. The calibration method described, which has been termed the Delta-Z Method, may be useful for in-situ monitoring of transducer sensitivity in installations which can be flooded and purged.
