An Introduction to Aeroacoustics is an introductory textbook covering the fundamental theory of aeroacoustics and its applications. The applications considered include aircraft noise, underwater noise, wind turbines, medical and biological systems, domestic appliances and musical instruments. It covers introductory classical acoustics and mathematical methods and includes examples and exercise problems. An Introduction to Aeroacoustics covers a broad range of acoustic topics, including duct acoustics, acoustic propagation and jet noise. Chapters on flow instability and resonance and computational aeroacoustics are also included. A companion website hosting videos is also available.
