The Physics of Sound Waves (Second Edition)

Mehr zum Buch

This book explores the properties of sound waves in relation to musical instruments, sound perception, fast Fourier transform analysis, and the recording and reproduction of music. It offers a nontechnical overview of the modern musical scale, intervals, and the factors that influence the pleasantness of musical combinations. The text examines the perception of loudness and pitch, alongside sound equipment like microphones, amplifiers, mixers, and loudspeakers, detailing connections through hardwiring and wireless digital interfaces such as USB, Bluetooth, and MIDI. It covers the analysis, synthesis, recording, and storage of music, aiming to clarify technical terminology and explain analog and digital sound equipment specifications regarding performance and quality. Graphics and animations illustrate sound production in various instruments, with selected examples from diverse cultures. Each chapter includes topics for further discussion and concludes with questions and problems, with solutions and a mathematical description of waves provided in the appendix.
