About This Item

 

Full Description

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.
