Function –  FDM10 digital noise tester sensor sensitivity, high precision, wide range of application, can be widely used in a variety of environmental noise measurement. –  The application of FDM10 digital noise tester can provide the decibel number of noise, so that relevant measures can be taken to control and reduce noise. Sound is measured in decibels. –  Noise pollution is one of the most influential environmental pollution. Higher decibel noise can even cause serious damage to people’s eardrums, leading to deafness, insomnia, dizziness, headaches and so on. –  FDM10 digital noise tester is a noise detection and testing equipment for residential, production, construction sites, squares and other public places.
