Acoustic lighting in open-plan offices: reducing noise

Hang wide fixtures above each cluster of desks, at low height, to absorb reverberation where voices rise. Combine several light points with sound-absorbing bodies rather than a single central ceiling light, and favour felt or textile fibre, which dampen echo while lighting the workstations.

How can you reduce noise in an open-plan office?

Multiply absorbent surfaces overhead and break up the lighting. An open floor bounces voices off concrete, glass and the bare ceiling; wide felt shades hung above the workstations intercept these waves before they rebound. Lighting zoning also divides the space and calms the soundscape.

Noise on an open floor comes mainly from voices, not from the street. These mid frequencies tire concentration far more than sheer volume, and echo amplifies them from desk to desk.

Damping this reverberation with an acoustic light helps each team become more productive without headphones or high partitions.

The most accessible step is to install pendant lights with textile bodies, distributed above each group of desks rather than in the centre of the room.

For a complete commercial fit-out, we can support professionals from the initial survey of the floor to the choice of models.

Which material absorbs noise best?

Dense felt leads the way, followed by textile fibres and upholstered technical foams. These materials trap the mid frequencies of voices, where metal and glass reflect them. A thick, deep shade absorbs more than a thin dish: mass and exposed surface are what count.

Felt, fibres and suspended panels

A felt body several millimetres thick, mounted wide, acts as a small baffle above the workstation. The larger the face turned towards the noise, the more it absorbs.

Metal and glass keep all their aesthetic appeal, but for echo they work as accents, never above conversation areas. A deep sphere or tube shape exposes more absorbent material than a flat profile.

What our catalogue confirms

From a survey of 250 pendants in our catalogue as of 25 September 2026, the 2-year warranty and CE certification appear on 100% of listings, and the IP20 rating covers 92% of the survey, suited to a dry office floor.

The selection is reviewed by buyers on the reviews published on the Google listing, useful when you are hesitating between two formats.

How can you tackle noise at low cost?

Play with placement and layering before buying acoustic treatment. Lowering the pendants, adding one per cluster and switching off the large central ceiling light costs less than a suspended ceiling, and tackles noise at the source: above people's heads, where voices rise.

Three simple adjustments change the atmosphere without building work: lower the suspension height, multiply the light points instead of using just one, and direct the light onto the work surfaces as task lighting.

Zoning also makes each workstation more comfortable, because light placed where you work encourages people to lower their voices, which also applies to a desk light at home.

To position your pendants precisely on the plan of your floors, the team can discuss it with you and scope your lighting project.

How can you treat an existing ceiling without building work?

Suspend baffles and absorbent light fittings from the existing ceiling without touching it. Suspended mounting is fixed to a few anchor points and brings the absorbent surface down to the right height; you gain absorption without a suspended ceiling, without panels to lay and without closing off the volume.

This approach is especially worthwhile under high ceilings, where sound has time to bounce. In these volumes, it is better to light large volumes with several lowered pendants than with a single point lost under the ceiling.

Suspended baffles combine with light fittings: alternate a felt shade and a bare panel, aligned above each row.

Where should pendants be positioned above desk clusters?

Centre one pendant per cluster of desks, 60 to 80 cm above the work surface, not flush with the ceiling. This low height brings the absorbent material closer to voices and focuses the light on the workstation. Repeat the pattern from one cluster to the next for a consistent result and a visually structured floor.

For a row of desks, align several identical pendants at regular intervals, as you would to balance the light above a kitchen island.

Keep visual comfort consistent, without direct glare: a layer of softer ambient lighting complements the points above the workstations well.

The pairing of light and acoustics also matches the style of the floor, in line with the 2026 lighting trends.
