Design of Sound Source Localization System in Internet of Things Technology
The design and study of sound source localization technology can effectively acquire and apply sound infor-mation.Research methods include literature research and theoretical analysis.By utilizing a sound source localization sys-tem,speech information can be captured using microphones and analyzed and processed using digital signal processing techniques to determine and track the source and spatial location of the sound.Through testing,the system accurately lo-cates the position of the sound module,with an actual localization error of less than±3 cm and an angular error of ap-proximately 1°.The localization performance is stable and reliable,and the localization method is simple and convenient.The response time of the sound source indication control device is less than or equal to 5 seconds,with a positional devi-ation of less than 5 cm,enabling accurate indication of the sound source position.
