The Acoustic Passive RAdar (APRA) project focuses on the measurement of acoustic sound fields. These fields consist of a combination of pressure variations around atmospheric pressure and vibrations of the air molecules (particle velocity). By measuring the complete particle velocity field, one can detect the direction of sound.
