Why do planes get loud?
Why do planes get loud? A moving aircraft causes friction and turbulence, which triggers sound waves. Generally, the faster the aircraft is flying, the more turbulence and friction will occur. When the aircraft's landing gear and flaps are used, more noise is made because more resistance is being created.
