Abstract

Existing measures of speech intelligibility and speech privacy are not adequate for evaluating the speech security of closed offices and meeting rooms. The optimum frequency weighting for predicting the onset or threshold of intelligibility is different from that for predicting the threshold of the audibility or the cadence of speech sounds. Thus, speech security must be statistically described in terms of the percentage of listeners able to hear or understand speech from adjacent spaces.
