air column
Sound's invisible path
An air column is a vertical body of air, especially one enclosed in a tube or pipe.
In music, the vibrating air column inside wind instruments produces sound—its length determines pitch.
In meteorology, an air column refers to the atmosphere directly above a given point on Earth's surface, relevant to pressure calculations.
