Product description:

Sound Level Meter called (noise meter) is the most basic noise measurement instruments. Sound level meter generally consists of a condenser microphone, preamplifier, attenuators, amplifiers, frequency weighting network and RMS indication table top components. Sound level Total works: the microphone converts sound into electrical signals, and then by converting impedance preamplifier, so the microphone attenuator matching amplifier output signal to weighting network, the signal frequency weighting (or external filtering. device), and then by the attenuator and amplifier amplifies the signal to a certain magnitude, finally, after the digital circuit processor, display the corresponding values ​​on the LCD.
