This book offers a profound exploration of the acoustic world of animals. Organized into nine chapters by taxonomy—invertebrates, insects, amphibians, reptiles, fishes, birds, and mammals (subterranean, terrestrial, and marine)—it delves into sound production, sound reception, sound function, and the impacts of noise on these creatures. As the second volume of Exploring Animal Behavior Through Sound, it builds upon the bioacoustic concepts and methodologies established in the first volume. By attuning ourselves to the sounds of nature, we can gain valuable insights into animal behavior, distribution, and demographics, as well as their habitat characteristics and needs, and the effects of noise on their behavior. This book will serve as a valuable resource for students and researchers in animal ecology seeking to incorporate acoustics into their research toolkit, as well as for environmental managers in industry and government.

This book invites its readers to dive into the depths of marine mammal bioacoustics. The ocean is a noisy place—naturally as well as anthropogenically. Our book explores the fundamentals of ocean acoustics, revealing the intricate sources of underwater noise that challenge marine life. Readers delve into the unique vocalizations of mysticetes, odontocetes, pinnipeds, otters, and sirenians, uncovering their diverse communication in stormy waters. The book presents research on marine mammal hearing and the impact of noise on their physiology and behavior, from the subtle behavioral responses to the broader biological significance of these effects. With insights into the management of anthropogenic noise, this book equips students, researchers, environmental managers, policy makers, conservationists, and enthusiasts alike with vital knowledge for protecting our ocean’s acoustic environments.

Vibration and noise reduce the perceived quality, productivity, and efficiency of many and limit production speeds electromechanical systems. Vibration can cause defects during manufacturing and produce premature failure of finished products due to fa­ tigue. Potential contact with a vibrating system or hearing darnage from a noisy machine can produce a dangerous, unhealthy, and uncomfortable operating environ­ ment. Recent advances in computer technology have allowed the development of so­ phisticated electromechanical systems for the control of vibration and noise. The demanding specifications of many modern systems require higher performance than possible with the traditional, purely mechanical approaches of increasing system stiff­ ness or damping. Mechatronic systems that integrate computer software and hard­ ware with electromechanical sensors and actuators to control complex mechanical systems have been demonstrated to provide outstanding vibration and noise reduc­ tion. The current trends toward higher speed computation and lower cost, higher performance sensors and actuators indicate the continuing possibilities for this con­ trol approach in future applications.

Elektrofahrzeuge sind für Entwickler der Fahrzeug­akustik ebenso eine Heraus­forderung wie eine höhere NVH-Performance durch Leicht­bau­strukturen und kleinere Motoren mit Turbo­lader. Die Auto­mobil­forschung muss das Akustik­manage­ment im Fahrzeug neu denken. Die internationale Automotive Acoustics Conference bietet dazu als Fach­tagung das notwendige Experten­wissen, um die künftigen Anforderungen an Antriebs­strang, Antriebs­systeme und Fahrzeug­architek­turen zu erfüllen. Simulations­prozesse und Verfahren der Multi­physik sind dabei essenziell, um Ruhe in die Passagier­kabine zu bringen. Die Konferenz zur car acoustics bietet dazu neustes Experten­wissen.

The 26th International Symposium on Shock Waves in Göttingen, Germany was jointly organised by the German Aerospace Centre DLR and the French-German Research Institute of Saint Louis ISL. The year 2007 marked the 50th anniversary of the Symposium, which first took place in 1957 in Boston and has since become an internationally acclaimed series of meetings for the wider Shock Wave Community. The ISSW26 focused on the following areas: Shock Propagation and Reflection, Detonation and Combustion, Hypersonic Flow, Shock Boundary Layer Interaction, Numerical Methods, Medical, Biological and Industrial Applications, Richtmyer Meshkov Instability, Blast Waves, Chemically Reacting Flows, Diagnostics, Facilities, Flow Visualisation, Ignition, Impact and Compaction, Multiphase Flow, Nozzles Flows, Plasmas and Propulsion. The two Volumes contain the papers presented at the symposium and serve as a reference for the participants of the ISSW 26 and individuals interested in these fields.

The study of incompressible ?ows is vital to many areas of science and te- nology. This includes most of the ?uid dynamics that one ?nds in everyday life from the ?ow of air in a room to most weather phenomena. Inundertakingthesimulationofincompressible?uid?ows,oneoftentakes many issues for granted. As these ?ows become more realistic, the problems encountered become more vexing from a computational point-of-view. These range from the benign to the profound. At once, one must contend with the basic character of incompressible ?ows where sound waves have been analytically removed from the ?ow. As a consequence vortical ?ows have been analytically “preconditioned,” but the ?ow has a certain non-physical character (sound waves of in?nite velocity). At low speeds the ?ow will be deterministic and ordered, i.e., laminar. Laminar ?ows are governed by a balance between the inertial and viscous forces in the ?ow that provides the stability. Flows are often characterized by a dimensionless number known as the Reynolds number, which is the ratio of inertial to viscous forces in a ?ow. Laminar ?ows correspond to smaller Reynolds numbers. Even though laminar ?ows are organized in an orderly manner, the ?ows may exhibit instabilities and bifurcation phenomena which may eventually lead to transition and turbulence.
