Evaluation of speech intelligibility in open-plan offices

Résumé

In open-plan offices, ambient noise made of intelligible conversations is generally perceived as one of the most important annoyance for tasks requiring concentration efforts. This annoyance has been proved to lead to a decrease of task performance and to health troubles for people in the mean and long term (tiredness, stress, etc.) Consequently, the improvement of working conditions should pass by the evaluation of speech annoyance that could give rise to recommendations on the arrangement of the open-plan office and on acoustical treatment of walls, ceiling and furniture. In that context, a standard SRT (Speech Reception Threshold) measurement campaign was set up, in order to evaluate the effect of speech ambient noise on intelligibility. For the trial purpose, a large set of syllabically-balanced French sentences has been constituted from Combescure, Fourier and Hint sentences. The ambient noise was made of both synthetic (modulated white noise, speech like modulated white noise, inversed speech noise) and real recordings in open-plan offices. In parallel, a second measurement campaign with subjects was conducted whose aim was to study the influence of intelligibility on the performance and effort in the realization of a seriation task. Results showing some links between intelligibility, performance and effort are presented in the paper.
