Prediction of Speech Transmission Index in Open-plan Offices

چکیده
According to questionnaire studies, speech is the most annoying sound source in open-plan offices [1]. The most distracting speech comes from the nearest workstations. Therefore, speech privacy between workstations should be as high as possible, that is, the speech transmission index, STI, should be low. This presupposes that the speech is properly attenuated, e.g. using absorbents, screens, and masked by using sufficient but not annoying background noise. Also the mutual distances and orientations of the workers are important.

Prediction of acoustical parameters for open plan offices according to ISO 3382-3
In the new international standard ISO 3382-3 the measurement procedure for open plan offices is described and a number of new room acoustical parameters for the objective evaluation are defined. Among the new parameters are the privacy distance and the distraction distance, both derived from the STI (speech transmission index) as a function of distance from the sound source. The final evaluatio...

متن کاملDescribing Levels of Speech Privacy in Open-Plan Offices
The primary goal of the acoustical design of conventional open-plan offices (cubicle style) is to achieve an acceptable level of acoustical or speech privacy. That is, we would like to make it more difficult for occupants to hear and understand speech sounds from adjacent workstations. We can therefore measure speech privacy by measuring the intelligibility of speech sounds from adjacent workst...
