A call center in Scottsdale, Arizona asked Noise Expert to evaluate speech privacy at their open office facility. They currently use a masking system that had inconsistent coverage to improve speech privacy. The noise between workstations travels by several paths, including, diffracting over the partitions, through the partitions, around the partitions, reflected off of the ceiling, reflected off of the walls, and reflected within the workstation walls to other workstations. The amount of noise from each path needed to be evaluated to determine the most effective treatment and the impact of any acoustical treatment. The background noise is another important factor in determining speech privacy. We made recommendations to treat the various paths – in order of effectiveness.
