The rich sound of musical wind instruments is a consequence of intricate phenomena involving the interaction between air flow and acoustic field, as well as the interaction between air flow and the structural components of the instrument. This book addresses the major aspects of the sound production mechanism in single-reed woodwind instruments and provides an extensive review of the theories related to flow-induced vibration and aerodynamic sound generation in internal flows at low Mach numbers and high acoustic amplitudes. In addition, the book presents a series of numerical techniques that can be used to assess this family of problems, thus providing a useful reference source for research areas such as duct acoustics, flow- induced vibration and aeroacoustics.
