Abstract

Specifies procedures for assessing the uncertainty in the acoustical measurements described in ISO 143-3 to ISO 140-9 due to random and systematic influences. Gives guidelines for determination of the repeatability value r and the reproducibility value R; verification of repeatability values r and reproducibility values R for different measurement arrangements in one laboratory and for comparisons between different laboratories; and application of repeatability values r and reproducibility values R in practice.
