AbstractThe term ?speech security' is used to describe very high levels of speech privacy sometimes required for closed meeting rooms. A room is said to be completely speech secure when persons outside the room are not able to understand conversations from within the meeting room, or in more extreme cases are not able to detect any speech sounds from the meeting room. The audibility and intelligibility of transmitted speech sounds are related to the level of speech sounds relative to existing ambient noise levels (i.e. signal-to-noise ratios) at locations outside the meeting room. The levels of speech sounds from adjacent meeting rooms will depend on the loudness of the speech in the meeting room and the sound transmission characteristics of the room boundaries.
