Sound source localization is a basic method for human and animal perception of the environment. The human and the animal determine the spatial position of the sound source through the auditory system, including determining the volume, position, distance, and the like of the sound source to sense the motion of the sound source. However, due to the limitations of our visual range of the naked eye, it is impossible to obtain the specific distribution information of the sound source.
With the development and popularization of information technology, an acoustic innovation technology that simulates a biological sound source localization system was born and played a vital role in many military and civilian systems. Sound source localization and imaging technology combines expertise in acoustics, signal detection, digital signal processing, electronics, software design, etc., by processing the received sound source signals, determining the geometric position of the sound source based on the data, and generating space in real time. The sound field distribution cloud image has a wide application prospect by visually reflecting the intensity and distribution of the sound through the color and brightness of the image display.
