Principles of marine bioacoustics by Whitlow W. L Au ( )
12 editions published between 2008 and 2009 in English and held by 519 WorldCat member libraries worldwide
Principles of Marine Bioacoustics is about studying the acoustics of marine animals using underwater acoustic techniques. The book discusses and unites the various areas of marine bioacoustics in a single comprehensive text. It covers important subjects associated with marine bioacoustics such as the measurement and generation of underwater sounds, the propagation of acoustic signals in the marine environment and in small tanks, signal processing techniques, and advanced devices used in the field. Also covered are topics relating to marine animals, such as methods to record and acquire acoustic signals from animals, their auditory systems and vocalizations, psychological and physiological testing procedures, and echolocation in marine mammals. This book is aimed at marine biologists and biological oceanographers. It is also relevant for professionals working with government agencies such as the National Marine Fisheries Service or organizations such as the Association of Zoos and Aquariums
The sonar of dolphins by Whitlow W. L Au ( Book )
9 editions published between 1993 and 2012 in English and held by 399 WorldCat member libraries worldwide
The extraordinary ability of dolphins to echolocate has fascinated scientists and the public since its discovery in the late 1950's. The Sonar of Dolphins is the first book to summarize modern research on this subject, and presents a broad synthesis of this very interdisciplinary subject. The author is an internationally-recognized expert on dolphin sonar and is in a unique position to bring together research on the physiological, mathematical and engineering aspects of dolphin sonar. The Sonar of Dolphins will be of interest to auditory researchers, electrical engineers, acoustical physicists, and mammalian physiologists
Hearing by whales and dolphins by Whitlow W. L Au ( Book )
8 editions published in 2000 in English and held by 253 WorldCat member libraries worldwide
"In this volume, experts in different areas of the field provide an overview of the bioacoustics of whales and dolphins as well as a thorough introduction to the subject for investigators of hearing in other animals. Topics covered include the structure and function of cetacean auditory systems, the unique sound production system of odontocetes, acoustic communication, psychoacoustics , echolocation, and models of sound propagation."--BOOK JACKET

Acoustic Reflectivity of Nets: Implications Concerning Incidental Take of Dolphins by Whitlow W. L Au ( Book )
2 editions published between 1990 and 1991 in English and held by 2 WorldCat member libraries worldwide
Sonar target strength measurements of several types of nets and associated gear were made using simulated dolphin echo-location signals. The different types of nets included: (a) standard commercial monofilament gillnet used in the salmon mothership fishery; (b) prototype hollow core monofilament net, (c) Macah tribal cord setnet, and (d) multifilament nets. Target strength measurements were made at four angles of incidence, (normal to net), 15, 30, and 45. The standard gillnet had the smallest target strength which was relatively independent of the angle of incidence. The target strength based on the peak-to- peak values of the echoes varied from -59 to -62 dB. Using echo energy within the integration time of Tursiops truncatus, the target strength was found to be between -54 and 59 dB. Biosonar detection ranges for different sea state conditions were estimated using the noise-limited form of the sonar equation and target detection data obtained for Tursiops truncatus in Kaneohe Bay, Oahu, Hawaii. The results suggest that an echolocating dolphin should be able to detect a gillnet at ranges long enough to avoid entanglement, even in sea state 6 conditions. Several possibilities for the seeming inability of dolphins to detect gillnets are discussed
The morphology of backscatter from F-layer field-aligned irregularities at mid- and high-latitudes and the generation of these irregularities by Whitlow W. L Au ( Book )

Electromagnetic wave transmission through a parabolic plasma slab at arbitrary angles of incidence ( Book )
1 edition published in 1966 in English and held by 1 WorldCat member library worldwide
The power transmission and reflection coefficients are derived for electromagnetic waves propagating through a plasma slab having a parabolic electron distribution. The analysis considers transverse electromagnetic waves (TE Mode) impinging on a plasma slab at arbitrary angles of incidence. The solutions are in terms of complex hypergeometric functions and their derivatives. Numerical results for the transmission and reflection coefficients are plotted as functions of peak plasma frequency, peak collision frequency, signal frequency, slab thickness, and angle of incidence. The results of this study can be applied to transmission of electromagnetic energy through laboratory plasmas that are bounded by walls. Numerical results are in agreement with experimental results for a rectangular glow discharge plasma. (Author)

Underwater Audiogram of a False Killer Whale (Pseudorca crassidens) ( Book )
1 edition published in 1988 in English and held by 1 WorldCat member library worldwide
Underwater audiograms are available for only a few odontocete species. A false killer whale (Pseudorca crassidens) was trained at Sea Life Park in Oahu, Hawaii for an underwater hearing test using a go/no-go response paradigm. Over 6-month period, auditory thresholds from 2-115 kHz were measured using an up/down staircase psychometric technique. The resulting audiogram showed hearing sensitivities below 64 kHz similar to those of belugas (Delphinapterus leucas) and Atlantic bottlenosed dolphins (Tursiops truncatus). Above 64 KHz, this Pseudorca had a rapid decrease in sensitivity of about 150 dB per octave. A similar decrease in sensitivity occurs at 32 kHz in the killer whale, at 50 kHz in the Amazon River dolphin, at 120 kHz in the beluga, at 140 khz in the bottlenosed dolphin, and at 140 kHz in the harbor porpoise. The most sensitive range of hearing was from 16-64 kHz (a range 10 dB from the maximum sensitivity). This range corresponds with the peak frequency of echolocation pulses recorded from captive Pseudorca. Keywords: Reprints, Marine biology

Insights into dolphin sonar discrimination capabilities from human listening experiments by Whitlow W. L Au ( Book )
1 edition published in 1989 in English and held by 1 WorldCat member library worldwide
A variety of dolphin sonar discrimination experiments have been conducted, yet little is known about the cues used by dolphins in making fine target discriminations. In order to gain insights on cues available to echolocating dolphins, sonar discrimination experiments were conducted with human subjects using the same targets employed in dolphin experiments. When digital recordings of echoes from targets ensonified with a dolphinlike signal were played back at a slower rate to human subjects, they could also make fine target discriminations under controlled laboratory conditions about as well as dolphins under less controlled conditions. Subjects reported that time-separation-pitch and duration cues were important. They also reported that low-amplitude echo components 32 dB below the maximum echo component were usable. The signal-to-noise ratio had to be greater than 10 dB above the detection threshold for simple discrimination and 30 dB for difficult discrimination. Except for two cases in which spectral cues in the form of 'click pitch' were important, subjects indicated that time-domain rather than frequency-domain processing seemed to be more relevant in analyzing the echoes
