Acoustic Treatment for Restaurants and Cafés
A noisy dining room loses covers. Where the noise comes from, what to treat first, and how to keep the design language you have already chosen.

A dining room that is too loud loses covers. Guests leave early, staff raise their voices, and the noise the guests make feeds the room further. It is one of the few design problems with a direct revenue cost.
Why restaurants get loud
- Occupancy raises the noise floor. Every additional table adds sound. A room that was fine at 40% occupancy fails at 100%.
- Hard surfaces in quantity. Glazing, tiles, exposed concrete, metal furniture and hard floors.
- Long, flat rooms. Reflections travel far and arrive late.
- Open kitchens and hard-fronted bars. Continuous sources with hard reflective faces.
- Design intent. Industrial and brutalist interiors are often intentionally hard, which is exactly what makes them loud.
Where to treat, in order
- Ceiling. The largest uninterrupted surface and usually the most available. Baffles and clouds work where no full ceiling covering is possible.
- Upper walls. Above head height, where it damages no upholstery, no artwork, and where nobody touches the panels.
- Under furniture. Banquette backs, table undersides and seat bases all absorb sound where guests actually sit.
- Soft finishes. Curtains, upholstery and carpet reduce the load before any panel is added.
What to avoid
- Panels where guests will touch them. Food, grease, cleaning chemicals and chairs all damage a soft felt surface. Keep panels above head height or behind the banquette.
- Treating only the walls and ignoring the ceiling, the most common and least effective spend.
- Choosing by colour alone in a kitchen-adjacent space. Light colours show marks; darker tones age better in service areas.
Keeping the design language
Hospitality projects are visually led, and acoustic products are often rejected because they read as "acoustic". Modern felt panels do not have to. Fluted profiles, laser-cut screens and baffle arrangements can carry the room's design language while doing the acoustic work. Treating the ceiling with baffles in a colour drawn from the palette keeps sightlines clean and design intent intact.
Numbers to specify
- Reverberation time for the room at its design occupancy
- NRC or alpha-w with the mounting condition for every product proposed
- Cleaning and maintenance regime, agreed at specification stage rather than after installation
Practical notes from service environments
- Order spare panels in the original colour batch; matching later is difficult
- Agree the cleaning method before installation, and check the panel can take it
- If the kitchen pass is adjacent, treat the pass ceiling first — it is often the worst surface in the building
