دانلود کتاب The Physics of Sound

The Physics of Sound was written for an introductory course in acoustics for nonscientists. A background in neither physics nor mathematics above high school algebra is required. Traditionally, such courses have been tailored to music majors nonmusicians either do not enroll or do not fully appreciate the physical principles because they are applied almost exclusively to musical topics. We have tried to avoid this limitation by dividing the text into three main sections. Chapters 1-4 present the basic physics essential for virtually all topics in the text: simple harmonic motion, wave principles, resonance, standing waves, the overtone series, Fourier synthesis, and spectrum analysis. No previous musical knowledge is required to appreciate these chapters, and a brief summary of the basic musical notation used in these chapters is provided in Appendix A. Applications and illustrations come from a variety of musical and nonmusical areas. We have revised Chapter 1 with additional discussion of SHM and apply these concepts to debunking psychokinetic myths. Our discussion of wave properties of sound in Chapter 2 has been revised to include adiscussion of modern applications such as noise cancellation technology, highway noise barriers, and ultramodern sonogram technology...
