Conversation radius of distraction
Sound is easily transmitted throughout open-plan offices, given that there are no doors or walls to block propagation. Conversations are clearly percieved, which disturbs colleagues both nearby and further away. Sound masking raises the acoustic comfort level of open-plan offices by reducing the distraction radius. Hence, people are significantly less distracted by conversations that take place within a radius of 15 to 40 feet from where the sound-masking loudspeaker is located.
