This paper investigates variability in the key ISO 3382-3:2012 metrics based on two types of repeated measurements in open-plan offices – Type1, where the same path over workstations was measured from opposite ends, and Type2, where two different measurement paths were measured. Per metric, analyses performed used (i) the range of observed values; and (ii) the observed values. Results from category (i) analysis: mean(∆Type1), and 95% confidence intervals were 1.2 m(0.9,1.5) for rD; 0.8 dB(0.6,1.0) for D2,S; 1.2 dB(0.8,1.5) for Lp,A,S,4 m; and 1.2 dB(0.7,1.7) for Lp,A,B. mean(∆Type2) were between twice and thrice the respective values of mean(∆Type1). Results from category (ii) analysis: the reliability, based on intra-measurement correlation coefficient, was fairly high for all metrics, except for Lp,A,S,4 m for Type2 repeats. The repeatability limit/coefficient (r) was 2.5 m for rD; 1.7 dB for D2,S; 2.9 dB for Lp,A,S,4 m; and 3.0 dB for Lp,B, for Type1 repeats. The r¬ values for Type2 repeats were substantially higher except for D2,S. Overall, most of the Type1 results seem reasonable considering repeats were conducted in complicated room acoustic environments, while Type2 repeats needs larger sample sizes in future studies. Some recommendations are outlined for ISO 3382-3 vis-à-vis Type1 and Type2 repeats.
