ASA S1.4 Part 1 – American National Standard for Electroacoustics – Sound Level Meters – Part 1: Specifications (a nationally adopted international standard). (Revision of ANSI S1.4-1983 (R2006), ANSI S1.4a-1985 (R2006) and ANSI S1.43-1997 (R2007))

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.
