Answer 1

An airstream mechanism that involves air being drawn in rather than pushed out is referred to as a "negative pressure" or "inhalation" mechanism. In phonetics, for example, this type of airstream mechanism is often associated with certain speech sounds produced by drawing air into the vocal tract, as opposed to expelling air, which is known as a "positive pressure" or "exhalation" mechanism. In specific contexts, such as ventilation systems or certain types of engines, it may also be referred to as "induction" or "suction."
