Open-Plan Office Acoustics: Fixing Speech Privacy and Distraction

Absorb, block, cover

Workplace acoustics stands on three legs. Absorb: a high-NRC ceiling to stop reflections carrying speech across the floor. Block: screens and partitions to interrupt direct paths between desks. Cover: electronic sound masking to raise the background just enough that distant speech becomes unintelligible.

Most failed offices have only one leg — usually screens. Screens without a good ceiling achieve little, because speech simply reflects over them off the soffit.

The ceiling does the heavy lifting

Specify the ceiling first: NRC 0.80+ acoustic tiles or a seamless acoustic ceiling across the whole floor plate. Where the design exposes the soffit, suspended baffles and clouds deliver equivalent absorption — sized by a reverberation calculation, not by how they look in the render.

• Full acoustic ceiling — best performance per dirham, suits enclosed services
• PET or fabric baffles — for exposed soffits, industrial aesthetics
• Ceiling clouds — over collaboration zones and circulation
• Acoustic lighting rafts — combined light and absorption over bench desks

Screens, booths and zoning

• Desk screens of 1.5 m+ with an absorptive core — fabric-faced, not bare laminate
• Acoustic phone and focus booths with rated doors for confidential calls
• Soft seating and quiet libraries of wall panels in collaboration zones
• Zoning: loud functions (sales floors, cafés) physically separated from focus work

Sound masking: the final 20%

In very quiet offices, a distant conversation stands out precisely because the background is silent. A tuned sound-masking system raises the ambient level by a few decibels with an unobtrusive spectrum, making speech beyond a few metres unintelligible. Masking multiplies the value of the ceiling and screens — it does not replace them.
