Principle and Application of Sound Level Meter

Sound level meter is the most basic instrument for measuring noise.
It belongs to an electronic instrument.
Sound level meter is generally composed of condenser microphone, preamplifier, attenuator, amplifier, frequency weighting network and RMS indicator
.

According to the sensitivity of the sound level meter, it can be divided into two categories, one is the ordinary sound level meter; the other is the precision sound level meter, which can also be divided into two categories according to the use of the sound level meter: One type is used to measure unsteady noise and impulse noise
.

The sound level meter adopts digital detection technology, which greatly improves the stability and reliability of the instrument
.

The sound level meter has the advantages of simple operation and convenient use; it has the characteristics of large dynamic range, large-screen LCD digital display, automatic measurement and storage of various data,
etc.

Sound level meters can be widely used in industrial noise measurement and environmental noise measurement of various machines, vehicles, ships, electrical appliances, etc.
