Audio sound wave vibration life detector omnidirectional audio vibration sensor

Audio sonic vibration life detector, all-round audio vibration sensor, audio life detector, also commonly known as sonic vibration life detector, is an acoustic detector used to detect and locate people buried in collapsed buildings due to earthquakes, explosions, landslides, mining accidents or building depressions Survivors in structures. Audio life detectors can detect these life signals through special sensors that sense subtle vibrations.
The audio life detector uses a special microelectronic processor that can identify tiny vibrations propagating in the air and solids. It is suitable for searching for survivors trapped under concrete tiles and other solids, and can accurately identify survivors. Sounds such as shouting, slapping, scratching and percussion. At the same time, the surrounding background noise can also be filtered. The search for survivors after a disaster is like a race against time. Life detectors can help rescuers locate survivors who move to knock or call for help. Experience shows that survivors buried under collapsed buildings can often hear rescuers, but rescuers cannot hear them. Concrete and gravel will block all sounds, but if the survivor can, knock, scrape or move, the structure can still effectively transmit these sounds. These sounds, the human ear can hear, but they can be Electronic equipment picked up.
Product advantages
*Integrate two highly sensitive omnidirectional audio vibration sensors, which can pick up extremely weak sounds
*Each sensor is equipped with a meter cable, and the detection range is larger
br/> * Equipped with professional noise reduction monitoring stereo headphones, which can effectively avoid external noise interference
