Product  description :

 

Sound level meter and meter (noise) is one of the most basic noise measuring instrument. Sound level meter usually consists of condenser microphone, preamplifier, attenuator, amplifier, frequency meter, power networks and RMS indicating meter, etc. Sound level meter, the working principle is: by microphone convert sound into electrical signals, then by impedance preamplifier transformation, match with microphone attenuator. Amplifier the output signal to the power network, the signal frequency meter right (or external) filter, and then by the attenuator and the amplifier will signal amplified to a certain amplitude, finally after dealing with the digital circuit processor and displayed on LCD and the corresponding numerical values.
