Partitions can only improve the overall acoustic environment of open-plan workspaces by reducing reverberation and achieving limited directional sound attenuation. They fail to deliver two-way sound insulation: they cannot block ambient office noise from reaching call microphones, nor prevent call audio from disturbing nearby colleagues. Partitions typically offer an equivalent of 8–15 dB, which is insufficient to eliminate Induced Speech Exposure (ISE) or provide effective speech privacy in standard office settings.
