Aero acoustics

Aero acoustics is a subfield of acoustics that studies noise caused by aerodynamic forces interacting with surfaces or turbulent fluid motion. The production of noise can also be linked to shifting flows on a regular basis.The most prevalent physical source associated with the field of aero acoustics is the production of sound by a turbulent flow. Although the term "aero" refers to air, the study of "aero acoustics" encompasses more than just noise caused by airflow. The general interaction between an acoustics field and a background flow is the focus of aero acoustics. Aero acoustics, for instance, is the study of how the flow in a muffler affects transmission loss or the reflections of sound off a shear layer.
