Sound source localization imaging testing and analysis system

The Norsonic 848A sound source localization imaging testing and analysis system uses a large number of microphones to avoid false signals. Compared with traditional sound imaging techniques, it has higher directionality and fewer misjudgments in sound source location search. It has three microphone sizes of 128, 256, and 384, with a high sound pressure value of 110db and a bandwidth of 20Hz-20KHz.

It has three microphone sizes of 128, 256, and 384, with a high sound pressure value of 110db and a bandwidth of 20Hz-20KHz. With a larger number of microphones, higher resolution, and less false error, digital microphones do not require additional analog-to-digital conversion devices, only network connections. Digital microphones have higher dynamic range and reliability, arranged in a circular manner to provide uniform frequency response and reduce the occurrence of false signals. A virtual microphone can analyze and listen to sound in real-time, locate the sound source in real-time, and filter out the audio range. The microphone on the disc can prevent sound and echo from behind, and each microphone records signals. The tachometer option can be expanded to assist in the analysis of rotating machinery, with multi-functional integration, without the need for additional signal processing units.
