    Abstract - (Show below) - (Hide below)

    IEC 61672-1:2013 gives electroacoustical performance specifications for three kinds of sound measuring instruments: - time-weighting sound level meters that measure exponential-time-weighted, frequency-weighted sound levels; - integrating-averaging sound level meters that measure time-averaged, frequency-weighted sound levels; and - integrating sound level meters that measure frequency-weighted sound exposure levels
