SubjectSpeech security
AbstractArchitectural speech security refers to the inability of eavesdroppers to hear speech sounds from nearby meeting rooms and offices where confidential material is being discussed. (Here ?architectural' refers to the security provided by the building structure and associated building systems such as ventilation systems). The audibility of speech sounds from meeting rooms will depend on how loud the transmitted speech sounds are relative to the existing ambient noise levels. It is therefore necessary to know the values of typical speech levels generated in meeting rooms and the levels of typical ambient noises in spaces near meeting rooms. This report presents the results of extensive measurements of speech sounds in meeting rooms and ambient noises in nearby spaces. The probability of various speech and noise levels occurring is reported and recommendations are made for using these results in calculations to estimate the architectural speech security of particular offices and meeting rooms.
