Tips: The main application areas of sound level meters

The sound level meter is a basic instrument for measuring noise. It is an electronic instrument. The 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. According to the sensitivity of sound level meters, they can be divided into two categories. One is ordinary sound level meters, the other is precision sound level meters. According to the purpose of sound level meters, they can also be divided into two categories: one is used to measure stability. State noise, one type is used to measure unstable noise and impulse noise.

The digital detection technology adopted by the sound level meter 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.

The sound level meter can be widely used for industrial noise measurement and environmental noise measurement of various machines, vehicles, ships, electrical appliances, etc. It is suitable for factories and enterprises, architectural design, environmental protection, labor and health, transportation, teaching, medical and health, scientific research and other departments.
