When singing or speaking, an airstream is forced upwards through the trachea from the lungs. These valves function mostly as articulators in the airstream and shapers of vocal tract resonance. The airstream escapes through a narrow groove formed in the centre of the tongue, causing friction between the tongue and the alveolar ridge. A splitter plate separated the wind tunnel into two sections whereby two independent airstreams were generated. The forcing of the airstream through the vocal folds in this state sets them into vibration. In a pulmonic egressive airstream mechanism, a coronal and a velar closure cannot be formed simultaneously. An egressive pulmonic airstream creates different aerodynamic conditions before and after the arrest phases of a plosive. Different airstream mechanisms are discussed on other screens, which also include animated figures illustrating the dynamics of the various airstream mechanisms. For /l/ the tongue must simultaneously produce an occlusion in the midline and an aperture on one or both sides of the midline to produce a lateral airstream. Forest canopies intercept nutrients and detritus from the airstream or higher canopy levels, providing habitat and resources for detritivores adapted to the warmer, drier canopy environment. Parallel-twins are usually mounted transversely, with the cylinders side by side above the crankshaft, and with exhaust pipes at the front, in the cool airstream.

Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence.
