    Decibel Meter

    Overview
    The decibel meter converts sound signals into electrical signals via its built-in microphone, then amplifies and applies frequency weighting through its circuitry to display the sound pressure level value. It is used to measure environmental noise, industrial equipment operation sounds, and product acoustic performance testing, and is commonly employed in factory workshops, urban road traffic, and household appliance testing.
    Selection
    When selecting a sound level meter, ensure the measurement range covers the actual sound pressure levels, the frequency response meets testing standards, and the accuracy satisfies error requirements. Consider environmental adaptability, such as the impact of temperature and humidity, and verify the validity of the calibration certificate. Ensure interface functions align with data recording needs and that ease of operation suits the intended usage scenario.
