Lecture: Measurement uncertainty and the components of variance in airborne sound insulation testing for 'Heavy Concrete Floors
Author(s): Whitfield Bill, Fenlon John
Summary:
This paper builds on earlier research which identified the components of variance associated with airborne sound insulation testing on lightweight Timber Floors. It uses a specific design of experiment (DOE) to draw out the component of variance due to the part, the operator and the instrumentation being used and is commonly known as a Gauge Repeatability and Reproducibility (GRR) experiment. The Analysis of variance (ANOVA) is based on a balanced two-factor crossed random model with interaction and targets the uncertainty due to the variability of the part, the operator and the instrumentation (Test kit) and also identifies if there is any interaction between the operators and the part being measured.
