AbstractA measurement procedure has been developed for rating the architectural speech security of closed offices and meeting rooms. It is based on measuring the attenuation between average levels in the meeting room and received levels at spot locations outside the room, 0.25 m from the room boundaries. These attenuations are used with statistical distributions of speech and noise levels to calculate a suitable signal-to-noise measure. This previously derived objective measure is related to the audibility and intelligibility of the transmitted speech. The measurement at spot receiver locations allows detection and characterization of localized weak spots (?hot spots?) in the room's boundaries.
