FNIRSI FDM01 digital noise tester is a device used for noise detection and testing in public places such as residences, production, construction sites and squares. Noise is one of the most influential environmental pollutants. Higher decibel sounds can even cause serious damage to human eardrums, resulting in deafness, insomnia, dizziness and headaches. The application of FDM01 digital noise tester can provide the decibels that the noise reaches so that relevant measures can be taken to control and reduce the noise. The unit of measurement for sound is the decibel. FDM01 digital noise tester has a very sensitive sensor, high precision, wide application range and can be widely used in noise measurement in various environments.
