Product Details
The working principle of the noise meter is that the sound is converted into an electrical signal by the microphone, and then the impedance is transformed by the preamplifier to match the microphone and the attenuator. The amplifier adds the output signal to the weighting network, performs frequency weighting on the signal (or an external filter), and then amplifies the signal to a certain amplitude through the attenuator and amplifier, and sends it to an effective plant detector (or an external power supply). flat recorder), the numerical value of the noise level is given on the indicator head
