Smart Sensor AS824 Sound Level Meter

Sound level meter, also known as (noise meter) is the most basic instrument in noise measurement. A sound level meter is generally composed of a condenser microphone, a preamplifier, an attenuator, an amplifier, a frequency weighting network, and an effective value indicating meter. The working principle of the sound level meter is: the microphone converts the sound into an electrical signal, and then the preamplifier transforms the impedance to match the microphone with 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 the amplifier, and finally after being processed by the digital circuit processor, it is displayed on the LCD The corresponding value is displayed on the
