    Chapter 2: Theoretical Background Aeroacoustics

    Aeroacoustics provides such approximations and at the same time a definition of the acoustical field as an extrapolation of an ideal reference flow. The difference between the actual flow and the reference flow is identified as a source of sound. This idea was introduced by Lighthill (1952, 1954), who called this an analogy. A second key idea of Lighthill s (1954) is the use of integral
