doi.org/10.1111/j.1600-0668.2005.00391.x · Finding checked against the abstract
Source details checked refers to publication information or an official source page. See the record’s limitations for incomplete extraction and the method for how to read the labels.
What the source reports
A model built from published studies predicts that performance starts to fall once nearby speech passes a speech transmission index of 0.2 and reaches its greatest loss by 0.6. Reported decrements range from 4 to 45% by task.
Design questions and applications
Design open-plan offices to lower speech intelligibility.
