Measurement Uncertainty in Audio Testing
Presenter:Bruce Hofer, Audio Precision, Inc. - Beaverton, Oregon, USA
Abstract:
All measurements are subject to some degree of uncertainty including such factors as readout resolution, short term stability and temperature effects, and estimates of error with regard to national standards. Reported measurement results should also contain an estimate of their respective uncertainties so that comparisons can be meaningful. In the world of metrology, this process of reporting measurement uncertainty is very strict requiring either some knowledge about the distributions of the various factors and the concept of standard deviation. This session will briefly discuss some of the uncertainty factors that can affect traditional audio measurements.
