Résumé

Measured room impulse responses are inherently uncertain like all measured quantities. This input uncertainty naturally propagates to derived metrics such as room acoustic single number quantities. Based on the framework provided by the Guide to the Expression of Uncertainty in Measurement (GUM), the example of the clarity parameter is taken to discuss its uncertainty due to the uncertainty of measured impulse responses. The discussion initially targets the basic and standardized version of clarity. In a second step it is investigated how the correction by Lyndeby (to avoid errors due to noise in the measured RIR) affects the uncertainty of the parameter. This contribution concludes with evaluating the significance of the found uncertainties.
