Résumé

A method in which attenuations between room-average sound levels in meeting rooms to spot receiver positions near the outside of rooms was proposed to evaluate the speech security of the room. It avoids problem with ill-defined receiving spaces, and spaces that do not have even approximately diffuse sound fields. It also provides assessments of speech security for more sensitive locations where an eavesdropper is more likely to be found. The method can predict transmitted sound levels 0.25 from the outside of the meeting room.
