    Abstract - (Show below) - (Hide below)

    This part of ANSI/ASA S1.4 / IEC 61672 gives electroacoustical performance specifications for three kinds of sound measuring instruments: -a time-weighting sound level meter that measures exponential-time-weighted, frequency-weighted sound levels; -an integrating-averaging sound level meter that measures time-averaged, frequency-weighted sound levels; and -an integrating sound level meter that measures frequency-weighted sound exposure levels.
