How far do you speak in the office?
Should we just accept that it takes 20 metres for the sound level of someone's voice to drop to a comfortable non-distracting level, or should we reduce this to 10 metres so that workgroup-to-workgroup distractions are minimized?

Open-plan office noise: The susceptibility and suitability of different cognitive tasks for work in the presence of irrelevant speech
The aim of the present study was to test which tasks are suitable for work in open-plan offices according to how susceptible they are to disruption produced by the mere presence of irrelevant speech. The tasks were chosen to tap fundamental capacities of office work involving: search for relevant information, remembering material, counting, and generation of words. The hypothesis was that tasks requiring semantic processing should be impaired by irrelevant speech. To determine the magnitude of performance decrease, two sound conditions (quiet, irrelevant speech) were compared. The results showed...
A combination of parameters is necessary for the characterization of the acoustical conditions of open-plan offices
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). With room acoustic simulation software these measurements can be simulated, thus providing a tool for the acoustical design of open-plan offices. The paper presents an example office with a range of alternative acoustical solutions that include different amount of absorption...
Une nouvelle norme pour mesurer l'acoustique de bureaux à aires ouvertes
L'ISO 3382-3:2012 spécifie les méthodes de mesurage des propriétés acoustiques des salles dans les bureaux ouverts avec mobilier. Elle décrit les modes opératoires de mesurage, l'appareillage nécessaire, la couverture requise et la méthode d'évaluation des données et de présentation du rapport d'essai. Les résultats des mesurages peuvent être utilisés pour évaluer les propriétés acoustiques des salles dans les bureaux ouverts. L'ISO 3382-3:2012 est destinée...
