Air pressure can induce a voltage in a piezoelectric crystal, but this effect is contingent upon the permeability of the crystal. While piezoelectric materials are commonly utilized as absolute pressure sensors, the specific setup and application may influence whether a mechanical compression is necessary to generate a piezoelectric effect. The discussion highlights the importance of understanding the material properties of piezoelectric crystals in relation to air pressure changes.
