Detection of Localized Sound Leaks in Walls and Their Effects on the Speech Privacy (Security) of Closed Rooms

Document Thumbnail

A new speech privacy measurement procedure accurately indicates the degree of speech privacy at individual listening locations outside of a closed room, including near localized weak spots. To investigate the importance of various defects (such as penetrations, electrical outlets), they were introduced into a test wall dividing two reverberation rooms. For each configuration of the wall, the following sound transmission measurements were made from one room to the other: i.) a standard transmission loss test, ii.) the new speech privacy measurement procedure, and iii.) impulse response measurements to a highly-directional spherical microphone array. The results indicate the degree to which the various defects affect the speech privacy conditions, and the extent to which they are detectable by the various methods.
