The objective of this Standard is to provide electroacoustical performance specifications for three kinds of sound measuring instruments: (a) timeweighting sound level meters that measure exponentialtimeweighted, frequencyweighted sound levels; (b) integratingaveraging sound level meters that measure timeaveraged, frequencyweighted sound levels; and (c) integrating sound level meters that measure frequencyweighted sound exposure levels.
