Which design strategies address acoustical privacy in open-plan offices?

• A. Hard surfaces, minimal furnishings, and long sightlines
• B. Absorptive panels, high-NRC ceilings, soft furnishings, and zoning
• C. Isolating each worker in sealed cubicles with no shared spaces
• D. Soundproof rooms only for management

Answer: (B)

In open-plan offices, improving acoustical privacy comes from reducing reverberation and dampening sound that travels between areas. The best approach combines absorption and thoughtful layout: absorptive panels on walls or partitions to cut reflections, ceilings with a high Noise Reduction Coefficient to absorb more sound, soft furnishings like carpets, upholstery, and textiles that further dampen noise, and zoning to create distinct quiet and activity zones so conversations and interruptions don’t easily spill into work areas. Together, these strategies lower overall noise and make speech less intelligible at a distance, which is what privacy in a shared space depends on. Hard surfaces and long sightlines tend to reflect and carry sound, increasing disruption; isolating everyone in sealed cubicles clashes with open-plan collaboration and doesn’t address the space-wide acoustics; and reserving soundproof rooms only for management leaves the rest of the space without improved privacy and isn’t practical for open-plan workflows.
