Abstract

A study was conducted to investigate the effects of room acoustics on the speech privacy of meeting rooms. The study found that the uniform weighted signal-to-noise ratio can be used to predict the intelligibility and audibility of speech inside a room. It was also observed that the the criterion values can be influenced by spatial and temporal room acoustics effects. The study used an initial listening test in free-field conditions to determine the signal-to-noise ratio. The intelligibility of the transmitted speech and the threshold of the intelligibility of the speech were found different. New listening tests was used to investigate the spatial and temporal room acoustics effects on the speech privacy. The spatial and temporal room acoustics factors can have a great impact on the speech privacy of an enclosed rooms.
