OVERVIEW

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.

AIMS AND CONTENT

LEARNING OUTCOMES

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.

 

TEACHING METHODS

Theoretical and applied lectures

SYLLABUS/CONTENT

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.
