Overview

Hong Kong Hima AR854 Sound Level Meter

Product Details

A sound level meter, also known as a noise meter, is the most basic instrument in noise measurement. A sound level meter generally consists of a condenser microphone, preamplifier, attenuator, amplifier, frequency weighting network, and effective value indicator head. The working principle of a sound level meter is that the sound is converted into an electrical signal by a microphone, and then the impedance is transformed by a preamplifier to match the microphone with an attenuator. The amplifier adds the output signal to the weighting network and performs frequency weighting on the signal（Or an external filter), then the signal is amplified to a certain amplitude through attenuators and amplifiers, and finally processed by a digital circuit processor to display the corresponding value on the LCD.
