Recently, a portable infrasound detector jointly developed by the China Aerospace Science and Industry No.2 Institute and the Institute of Acoustics of the Chinese Academy of Sciences was successfully developed and put into use.
Infrasound waves are sound waves with a frequency of 0.0001~20Hz. This frequency band is usually not perceived by the human ear, but since the natural frequency of various organs of the human body is also roughly in this range, high-power, high-intensity infrasounds will be generated in the human body once they are generated. The resonance effect will cause harm to the human body. 207 Institute and the Institute of Acoustics of the Chinese Academy of Sciences carry out in-depth cooperation, using their respective accumulation in acoustic detection and security, industrial monitoring product integration design, joint development of a portable infrasound detector, To achieve rapid detection and early warning of 'infrasound' pollution.
It is understood that the product is designed with a user-friendly visual interface, which can display sound pressure and audio curves, and display the infrasound accumulation in the environment with a color scale. The detection accuracy is high, and it can be used for security monitoring tasks in key resident locations. It is mainly detectable. In the environment, there is a continuous, inborn wave that may endanger health and provide early warning. At present, the first set of portable infrasonic detector has been put into use, and the equipment is running well.
