This paper discusses a type of 3-dimentional rapid sound source location method, which can be widely used in underwater or air environment, such as oil and gas exploration, fish characteristics research, remote conferencing and other fields. Delay-and-sum and Fast Direction of Arrival algorithm are discussed for narrowband signal processing. Sound source positioning only need to calculate and display the power intensity of each different angle of incidence, without the need to extract the specific incident signal, so we can directly apply FDOA algorithm. Since the center frequency of the sound signal is much lower than that of radio waves, laser and other signal carriers, the boundary conditions of the narrowband signal are often not satisfied in the actual workplace. Meanwhile, the system only needs the data characteristics of a certain frequency band in most applications. Therefore, this paper studies a fast beamforming and display method for specifying the frequency band and wave velocity, and verifies the validity of the relevant method with the delay-and-sum beamformer.
