Gêne dans les bureaux ouverts : Incertitudes des indicateurs de la norme ISO 3382 3 et proposition d’amélioration de la norme ISO 22955

open access: yes, 2022
La qualité acoustique des bureaux ouverts est évaluée au travers de la capacité de l’aménagement à limiter la propagation du bruit de parole, qui constitue la source principale de gêne dans ces espaces de travail. Pour cela, deux normes sont disponibles : la norme ISO 3382-3 qui est une norme de mesurage et la norme ISO 22955 qui fixe des valeurs ...

Simplified expressions of uncertainty for single number quantities in ISO 3382-3 (2022)

The Journal of the Acoustical Society of America
The ISO 3382-3 (2022) standard defines single number quantities (SNQs) characterizing the spatial decay of speech (D2S, LpAS4m, rC) and of its intelligibility (rD). The standard assesses the accuracy of the measurement using a unique uncertainty value for each SNQ, relying on a round-robin test performed in a single office. To make this assessment more

Prediction of acoustical parameters for open plan offices according to ISO 3382-3

The Journal of the Acoustical Society of America, 2012
In the new international standard ISO 3382-3 the measurement procedure for open plan offices is described and a number of new room acoustical parameters for the objective evaluation are defined. Among the new parameters are the privacy distance and the distraction distance, both derived from the STI (speech transmission index) as a function of distance
