Egressive sound

Pulmonic egressive sounds are those in which the air stream is created by the lungs, ribs, and diaphragm.

Pulmonic egressive sounds are found in all spoken languages.

The lingual egressive, also known as velaric egressive, involves a double closure similar to that of the lingual ingressive sounds known as clicks, but with airflow in the opposite direction.

With the velum closed, the speaker forces air out of the mouth using either the tongue or cheeks, as in the French expression of dismissal.

While not known to be used for normal vocabulary in any human language,[2] apart from the extinct Australian ritual language Damin, a variation of this airstream mechanism is known to musicians as part of circular breathing.
