Acoustic holography

Acoustic holography is a technique that creates detailed 3D images of sound fields, similar to how light holography produces images of objects. It captures sound waves emitted by an object or environment using an array of sensors, then uses advanced computer processing to reconstruct and visualize how the sound propagates through space. This allows for precise analysis of sound sources, vibrations, or defects in materials without physical contact. It’s useful in fields like acoustics research, audio engineering, and non-destructive testing, providing insight into complex sound patterns in a clear and comprehensive manner.
