Well-placed plants make the office more silent. A small “fence” around the workstation can reduce noise by 5dB. The positive contribution of plants to noise reduction has been well documented in the literature, among others Dr. Helen Russell, Oxford, England and David Uzzell, University of Surrey, England. While it would be difficult to document the cost of reducing office noise productivity, there is no need to go far enough to find an example. Anyone who ever worked in an open office can report that he offeten had to have break due to the annoying office noise. According to the United Organization of American Landscape Builders, indoor plant specialists can reduce this costly and “annoying decibels factor” by using green walls, green space deviders or other innovative plant groupings.
