Book Synopsis Development of a Modified Time Delay Spectrometry Technique for Underwater Acoustic Measurements in a Multipath Environment by :
Download or read book Development of a Modified Time Delay Spectrometry Technique for Underwater Acoustic Measurements in a Multipath Environment written by and published by . This book was released on 1984 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A measurement technique has been developed which makes possible the determination of the acoustic transmission loss for various paths between a source and a receiver at relatively short ranges in the ocean. The method is based upon a technique called Time Delay Spectrometry (TDS). The theory for utilizing TDS to perform measurements on an underwater test range with a homogeneous water column is presented. The experimental parameters concerning test geometry together with criteria for the source signal are discussed and the limitations are described. A computer program written in HP BASIC is the tool in a multipath measurement system where analog sound signals recorded on tape are processed by an HP 356A Dynamic Signal Analyzer under program control. Originator-supplied keywords include: Time Delay Spectrometry (TDS), Under water acoustic propagation, Dynamic signal analyzer, Linear frequency modified pulse (LFM pulse).

Book Synopsis Application of a Modified Time Delay Spectrometry Technique in Modeling of Underwater Acoustic Propagation by : Louis L. Prudhomme
Download or read book Application of a Modified Time Delay Spectrometry Technique in Modeling of Underwater Acoustic Propagation written by Louis L. Prudhomme and published by . This book was released on 1987 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of sound propagating by multiple paths in an ocean at short ranges has been conducted using a Modified Time Delay Spectrometry (TDS) technique. In this version of TDS, a source driven by a linear FM slide and an HP3561A Dynamic Signal Analyzer are used to measure the amplitude as a function of frequency of signals traveling by different paths and having different arrival times. Two sets of data from the acoustic test ranges at the Naval Undersea Weapons Engineering Station were analyzed for different environment conditions to determine the relative amplitudes of the directly propagating and surface reflected signals. Comparisons with simple rough surface scattering theory showed reasonable agreement. Results and control software are presented and discussed. Recommendations for future applications are made. Keywords: Multipath acoustic propagation; Time delay spectrometry; Surface reflection; Theses.

Book Synopsis Sound System Engineering by : Don Davis
Download or read book Sound System Engineering written by Don Davis and published by CRC Press. This book was released on 2014-06-20 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sound System Engineering Third Edition is a complete revision and expansion of the former work. Written by two leading authorities in the field of audio engineering, this highly respected guide covers the fundamentals necessary for the understanding of today's systems as well as for those systems yet to come. The space formerly occupied by outdated photographs of manufacturers' product and of older system installations has now been filled with new measurements and discussions of the measurement process. The "Mathematics for Audio chapter has been expanded to include the mathematics of phasors. The "Interfacing Electrical and Acoustic Systems chapter has a completely new section covering the analysis of alternating current circuits. Additionally, system gain structure is now treated by both the available input power method and the voltage only method, complete with illustrations of each. All chapters dealing with loudspeaker directivity and coverage, the acoustic environment, room acoustics, speech intelligibility, and acoustic gain appear in up to date versions. In addition there is new material on signal delay and synchronization and equalization. There are completely new chapters on microphones, loudspeakers and loudspeaker arrays including line arrays with steering and beam-width control, and signal processing, both analog and digital. The book runs the gamut of sound system design from the simplest all-analog paging system to the largest multipurpose digital systems. In writing this third edition, the authors kept in mind the needs of sound system installers, sound system service technicians, and sound system designers. All three groups will find the material to be useful for everyday work as well as beneficial in the furtherance of their overall audio education.
Book Synopsis Sound Systems: Design and Optimization by : Bob McCarthy

Available in PDF, EPUB and Kindle. Book excerpt: With this definitive guide to sound reinforcement design and optimization, Bob McCarthy shares his expert knowledge and effective methodology developed from decades of field and teaching experience. This book is written for the field professional as well as the consultant or student, in a clear and easy-to-read style and illustrated with color diagrams and screenshots throughout. McCarthy's unique guide reveals the proven techniques to ensure that your sound system design can be optimized for maximum uniformity over the space. The book follows the audio signal path from the mix console to the audience and provides comprehensive information as to how the sound is spread over the listening area. The complex nature of the physics of speaker interaction over a listening space is revealed in terms readily understandable to audio professionals. Complex speaker arrays are broken down systematically and the means to design systems that are capable of being fully optimized for maximum spatial uniformity is shown. The methods of alignment are shown, including measurement mic placement, and step-by-step recipes for equalization, delay setting, level setting, speaker positioning and acoustic treatment. These principles and techniques are applicable to the simplest and most complex systems alike, from the single speaker to the multi-element "line array.
