Measurements of sensory load from ventilation systems by trained and untrained panels

This paper studies the overall accuracy and comparability of both trained and untrained panels in order to determine the required size of the untrained panel, and to determine the limit value (mean vote) corresponding to an acceptable air quality. In the results, it is proposed to use an untrained panel of 15 persons. The risk connected with the use of such a small, untrained panel was calculated to be 10 % and is equivalent to trained panel.
