This book provides the material for an introductory course in engineering acoustics for students with basic knowledge in mathematics. It is based on extensive teaching experience at the university level. Under the guidance of an academic teacher it is sufficient as the sole textbook for the subject. Each chapter deals with a well defined topic and represents the material for a two-hour lecture. The 15 chapters alternate between more theoretical and more application-oriented concepts. They cover the following issues: Introduction - Mechanic and acoustic oscillators - Electromechanic and electroacoustic oscillations - Electromechanic and electroacoustic analogies - Electromechanic and electroacoustic transduction - Magnetic-field transducers - Electric-field transducers - The wave equation in fluids - Horn and stepped ducts - Spherical sound sources and line arrays - Piston membranes, diffraction and scattering - Dissipation, reflection and absorption - Geometric acoustics and diffuse sound fields - Isolation of air- and structure-borne sound - Noise control: a survey - Appendices, e.g, complex notation for sinusoidal signals, power and intensity.
