KeyGoTech DES-S162 Pad is a portable ultrasonic acoustic imager, and is one of the members of KeyGoTech "multi ear" acoustic camera series. This series of products is equipped with 162 high-sensitivity digital MEMS ultrasonic microphones. The microphone distribution is designed based on the equal area multi arm spiral, which ensures that DES-S162 has the advantage of acoustic positioning in the analysis frequency range of 2k~96k.

     The DES-S162 Pad is easy to carry and simple to operate. The instrument parameters can be set through the touch screen or keys, and the test frequency and range, dynamic range and threshold can be freely adjusted to achieve accurate testing in different scenarios and applications. It can also export data automatically or manually by the device through wired network, wireless WiFi, Bluetooth, USB and other diversified communication methods, so that it is convenient to find and report in time.

     KeyGoTech voiceprint probe is an integrated voiceprint pickup, which contains 64 pickup sensors to achieve ultra-high signal-to-noise ratio. It can collect weak sounds that cannot be distinguished by the human ear, providing a reliable signal source for the voiceprint fault diagnosis and recognition algorithm.

     KeyGoTech DES-C8 sensor is a compact, lightweight, intelligent and powerful voiceprint monitoring front-end, including eight high-precision digital microphones, which can achieve 7 × 24 hour continuous acquisition and analysis of sound signals, using array positioning and directional enhancement algorithms to improve the signal-to-noise ratio, free from environmental interference, provide reliable acoustic signals for voiceprint fault diagnosis and recognition algorithms.

     DES-C8 sensor covers audible sound and ultrasonic frequency band, and the pressure fluctuation during gas leakage will radiate ultrasonic signals. The voiceprint sensor can effectively pick up the characteristics of the leakage voiceprint for non-contact area monitoring.

     DES-C8 can be deployed in various ways and can be flexibly combined in series and parallel. One acquisition platform can support up to 8 voiceprint sensors. It can not only reduce the complexity of the current construction routing, but also accurately synchronize the sound signals between multiple voice print sensors, build a large distributed sound array, which is used to sense the global sound field information, improve the accuracy of voice print recognition and reduce the rate of misjudgment.
