According to the Learning outcomes and to the Syllabus (see links below), the course aims at proving the basic information about:
Noise generation from fluid machines,
Effects of noise on human beings, and
Aerodynamic noise reduction methods.
Basic information on Physical acoustics and signal processing is also provided, which is necessary for comprehension of the above listed contents.
Understanding of the origin of the aerodynamic noise, with reference to aeronautic applications. Basic planning of aerodynamic noise measurements, analysis of the results of sound pressure level measurements, identification of the active moise generating mechanisms. Theoretical basis for noise generating mechanisms control.
Theoretical and applied lectures
Basic principles of Physical acoustics and Psychoacoustics
Measurements techniques for sound pressure level and method for the analysis of experimental results
Elementary acoustic sources and wave propagation in ducts
Study and properties of the aerodynamically generated noise (Lighthill and Ffowcs-Williams Hawkings equations): noise generated by turbulence, jets, and interaction of fluid flow with solid bodies. Applications to turbomachines, propellers, and jet engines.
Laboratory classes.
