3D sound localization

3D sound localization refers to an acoustic technology that is used to locate the source of a sound in a three-dimensional space. The source location is usually determined by the direction of the incoming sound waves (horizontal and vertical angles) and the distance between the source and sensors. It involves the structure arrangement design of the sensors and signal processing techniques.

Most mammals (including humans) use binaural hearing to localize sound, by comparing the information received from each ear in a complex process that involves a significant amount of synthesis. It is difficult to localize using monaural hearing, especially in 3D space.
