Test Method for Determining Sound Reduction of Furniture Ensembles

摘要

Background. Speech is the most disturbing noise source in open-plan offices. The disturbance can be reduced by e.g. sound-absorbing materials, masking sound and screens between workstations. An additional reduction in speech level can be achieved by e.g. partially enclosed workstations, pods, sofa groups and chairs, and fully enclosed booths. However, there is no standardized method to declare the sound reduction properties of such ensembles.
