This didactic book presents the main elements of acoustics, aeroacoustics and vibrations. Illustrated with numerous concrete examples linked to solid and fluid continua, Acoustics, Aeroacoustics and Vibrations proposes a selection of applications encountered in the three fields, whether in room acoustics, transport, energy production systems or environmental problems. Theoretical approaches enable us to analyze the different processes in play. Typical results, mostly from numerical simulations, are used to illustrate the main phenomena (fluid acoustics, radiation, diffraction, vibroacoustics, etc.).

The Fundamentals of Sound Science teaches the principles of the physics of sound, as well as basic principles of physics, by linking them to music and musical instruments. The book begins by asking students to question the meaning of sound itself. What is sound? How far and how fast does it travel? By asking students to think about sound in this way, the material is able to connect our daily experience of sound to principles of physics such as distance, velocity, scalars, and vectors. Through the next six chapters students learn about harmonic motion, waves, the sources and physical properties of sound, and measurements of loudness. The second half of the book uses music as the vehicle for a deeper exploration of sound. Students study some basic musicianship, including articulation, intervals, and harmonic series. These concepts become the springboard for an examination of the Fourier Analysis of Simplest Sound Spectra, which encompasses steady tones, periodic waves of arbitrary form, square, triangular, and sawtooth waves, and modulated tones. Different families of instruments are discussed in depth: percussion, strings, flutes and recorders, woodwinds, and finally the human voice. The book concludes with a chapter on room acoustics, which covers the precedence effect and reverberations. Each chapter is filled with detailed explanations, and numerous examples are used to enhance student understanding. Study questions are included to encourage critical thinking, and prepare students for tests. Chapter summaries aid retention by reviewing terms and relations. By finding the common ground between physics and music, The Fundamentals of Sound Science strengthens understanding of both, revealing that many principles of the physical world are a part of our common, taken for granted, daily experience. All we have to do is listen. The Fundamentals of Sound Science can be used for introductory courses in physics, including those at the high school level. The accessibility of the material makes the book appropriate for non-majors at the university level, and students can achieve mastery of the content without a background in mathematics, making the book ideal for general education courses.

An introduction to dimensional analysis, a method of scientific analysis used to investigate and simplify complex physical phenomena, demonstrated through a series of engaging examples. This book offers an introduction to dimensional analysis, a powerful method of scientific analysis used to investigate and simplify complex physical phenomena. The method enables bold approximations and the generation of testable hypotheses. The book explains these analyses through a series of entertaining applications; students will learn to analyze, for example, the limits of world-record weight lifters, the distance an electric submarine can travel, how an upside-down pendulum is similar to a running velociraptor, and the number of Olympic rowers required to double boat speed. The book introduces the approach through easy-to-follow, step-by-step methods that show how to identify the essential variables describing a complex problem; explore the dimensions of the problem and recast it to reduce complexity; leverage physical insights and experimental observations to further reduce complexity; form testable scientific hypotheses; combine experiments and analysis to solve a problem; and collapse and present experimental measurements in a compact form. Each chapter ends with a summary and problems for students to solve. Taken together, the analyses and examples demonstrate the value of dimensional analysis and provide guidance on how to combine and enhance dimensional analysis with physical insights. The book can be used by undergraduate students in physics, engineering, chemistry, biology, sports science, and astronomy.

Die vollstandige Berechnung und Darstellung von Schallvorgangen macht schon in den Fallen, wo es sich im einfaohe Strahleranordnungen handelt, nicht unerhebliche Schwierigkeiten. Damit hangt es wohl zu- sammen, dass eine systematische Behandlung daruber nicht vorliegt. Im folgenden wird der Versuch gemacht, die grundlegenden Formeln und Begriffe zu entwickeln und an einer Reihe von einfachen Beispielen praktisch anzuwenden. Dabei erscheint es wegen der ausserordentlichen Vereinfaohung naturgemass, die Berechnung zunachst auf das Gebiet in grosser Entfernung vom Strahler zu beschranken. Bei dieser Ein- schrankung ergibt sich der UEbergang vom ungerichteten zum gerichteten Strahler sehr einfach, indem die Formeln des ungerichteten Schall- senders durch einen zusatzlichen Faktor, der als Richtfaktor bzw. Strah- lungsfaktor gekennzeichnet ist, erganzt werden. Auch maoht dann die Berechnung des Sohallfeldes von solchen Membranen, die im Gegensatz zur Kolbenmembran keine konstante Sohwingungsamplitude hab:: m oder Knotenlinien besitzen, keine besonderen Schwierigkeiten. Der zweite Teil behandelt die Darstellung des in unmittelbarer Nahe des Strahlers vorhandenen Schallfeldes. Der zunachst untersuchte Fall von zwei punktfoermigen Strahlern zeigt bereits, dass jetzt ganz wesent- lich kompliziertere Verhaltnisse vorliegen. Man ist daher auch ge- zwungen, das Schallfeld an jeder Stelle zu beschreiben. Das geschieht am einfachsten, indem man die Kurven zeichnet, fur welche die Druck- amplitude einen konstanten Wert besitzt. Oft ist es jedoch auch zweck- voll, Kurven konstanter Phase zu berechnen. Im Falle der kreisfoermigen Kolbenmembran, der praktisch von besonderer Bedeutung ist, ist es wesentlich, dass wenigstens die Werte auf der Mittelachse, auch in in- mittelbarer Nahe, sehr einfach angegeben werden koennen.
