Definition of Acoustic holography
Acoustic holography is a technique that allows three-dimensional distributions of sound waves called sound fields to be stored and reconstructed. To do this, sound passing through a surface is recorded as a two-dimensional pattern called a hologram (a type of interferogram). The hologram contains information about the phase and amplitude of the sound waves passing through. This pattern can be used to reconstruct the entire three-dimensional sound field. Acoustic holography is similar in principle to optical holography.
