Abstract
In accordance with some embodiments of the present disclosure, a process for determining a direction vector of a sound source is described. The process may be implemented to detect, by a first sound sensor, a first sound pressure of a sound wave propagated from the sound source, and detect, by a second sound sensor, a second sound pressure of the sound wave. The process may further be implemented to determine, by a processor, the direction vector of the sound source relative to the first sound sensor and second sound sensor, wherein the direction vector is based on the first sound pressure, the second sound pressure, and a first distance between a first physical location of the first sound sensor and a second physical location of the second sound sensor.

A method for determining a direction vector of a sound source, comprising:
- detecting, by a first sound sensor, a first sound pressure of a sound wave propagated from the sound source;
- detecting, by a second sound sensor, a second sound pressure of the sound wave;
- and
- determining, by a processor, the direction vector of the sound source relative to the first sound sensor and the second sound sensor, wherein the direction vector is determined based on a difference of the first sound pressure and the second sound pressure, an average of the first sound pressure and the second sound pressure, and a first distance between a first physical location of the first sound sensor and a second physical location of the second sound sensor.
