Description

This Standard gives electroacoustical performance specifications for three kinds of sound measuring instruments:

  1. time-weighting sound level meters that measure exponential-time-weighted, frequency-weighted sound levels;
  2. integrating-averaging sound level meters that measure time-averaged, frequency-weighted sound levels;
  3. integrating sound level meters that measure frequency-weighted sound exposure levels.

Sound level meters specified in this standard are intended to measure sounds generally in the range of human hearing. Two performance categories, class 1 and class 2, are specified.

Acceptance limits for class 2 are greater than, or equal to, those for class 1.

Scope

This standard is applicable to a range of designs for sound level meters. Sound level meters may include extensive analogue or digital signal processing, separately or in combination, with multiple analogue and digital outputs.

Sound level meters may include general-purpose computers, recorders, printers, and other devices that form a necessary part of the complete instrument. Identical to and reproduced from IEC 61672-1:2013 Ed 2.0.
