For hospitality operators & designers
Atmosphere, designed into the room.
Acoustic and sound design for restaurants, bars, members’ clubs and hotels in London. A room is making a sound whether or not anyone designed it. We design that sound on purpose.
That sound decides how long guests stay, how easily they talk, how much they spend and what they write afterwards. So the atmosphere you intend is the atmosphere your guests actually experience.
Zoned coverage across every table, foreground energy held at the bar, absorption mapped to the hard finishes. Toggle each layer on or off to explore how the room is resolved.

Designing atmosphere, not installing speakers
The commercial case for sound
Anyone can fit speakers to a ceiling. The harder and more valuable work is deciding how a room should feel, and then making it feel that way reliably, service after service.
Our approach is led by how people actually hear, not by an equipment list. Our Cognitive Load Index framework assesses how sound affects comfort, attention and fatigue, the difference between a room people tolerate and a room they settle into and stay.

01
Acoustic blueprint
Sonic strategy, system concept and spatial analysis. We define what the venue needs to sound like and map that against the architectural intent, materials schedule and MEP coordination.

02
Engineered procurement
Detailed specification, product selection and sourcing. Every component is chosen for the project, not from a template. We coordinate directly with contractors and the design team.

03
Precision commissioning
On-site installation oversight, system calibration and final tuning. We stay until the venue sounds exactly as intended, and we hand over a system the operators can actually use.

Restaurant sound system design
Loudspeaker specification, coverage and zoning resolved for the room, so music sits right across every table and holds through peak service.

Many rooms, many moods. Independent zones, foreground sound that holds at peak, and control built around how the venue actually runs.

Why rooms get loud, and how they are fixed
Noise is the most common thing guests complain about, and it is almost always a property of the room rather than the people in it. Restaurant acoustic design is the discipline of controlling that noise on purpose, so a room can feel full and alive without becoming a place nobody can talk in.
The Lombard effect
As a room fills, background noise rises. Guests instinctively raise their voices to be heard, which lifts the noise further, and the cycle repeats through service. A room that felt calm at opening becomes exhausting by the second sitting, without anything about the design having changed.
The cause is the room, not the system
A loud restaurant is usually a reverberant one. Sound reflects off the hard surfaces of a modern interior, glass, stone, concrete and exposed ceilings, and returns to the room instead of fading. No sound system can fix this, because the system was never the cause. We reduce reverberation by placing absorption where it does the most work.
Designed in, not bolted on
Panels added to a finished room work, but they announce themselves. Absorption designed in from the first drawing does the same job invisibly. We resolve the acoustic strategy and the visual strategy together, treating the largest reflective surfaces with finishes that read as design rather than correction, and zoning the room so the bar and the dining areas behave differently.
Atmosphere
Atmosphere is part of how the room performs
Sound is one of the few decisions that is at once a design decision and an operating one.
A guest feels a room before they can describe it. The way a space sounds shapes how long people stay, how freely they spend and what they say afterwards, so atmosphere is not a finishing layer. It is part of the operating model. Our journal on how sound affects dwell time and customer spend sets out the commercial case in full.
We take the sonic layer on as our own, from the schematic stage through to the night the doors open. Sound is brought in alongside lighting, materials and spatial planning, coverage is shaped for the room rather than for convenience, and the system is built so your team can run it without a second thought. Our approach to restaurant sound system design shows how that early involvement plays out, our premium audio installation service carries it through to commissioning, and you can read more on why restaurants sound the way they do.
Test your room
30-Second Acoustic Health Check
Using your device microphone, we take a quick indicative acoustic reading to understand how your room may affect speech clarity, listening comfort and overall acoustic performance. Best performed in an empty, quiet room with headphones disconnected.
Before you begin
- Stand roughly in the centre of the room
- Remain quiet while we measure ambient noise
- When prompted, clap once firmly and allow the sound to decay naturally
- The assessment takes approximately 30 seconds
Your browser will ask permission to use the microphone. Tap Allow to run the test.
After completion, you'll receive an indicative acoustic score and recommendations for improvement.
Audio is processed locally on your device and is never uploaded.

Why technically compliant rooms still fatigue
their occupants, and how to fix it.
Introducing the Cognitive Load Index (CLI),
a framework for measuring what people feel,

The best room in the city is the one nobody wants to leave.
Where sound should disappear, we fold it into the architecture. Where it should lift the room, we make it deliberate. Your venue should sound as considered as it looks, service after service.
Where it matters
Designed for how each room earns
Six environments, six different acoustic problems. We design each one around how the space is actually used. Service rhythm, occupancy, and the energy the room is meant to hold.
Fine dining & restaurants
Sound that turns covers into a longer evening
Acoustic comfort, discreet speaker placement, and zoning that shifts energy from lunch through to late-evening service.

Cognitive load assessment
Evaluation of listening effort across the venue using our proprietary CLI framework, ensuring guest comfort is maintained throughout service.
Proprietary CLI frameworkWe provide hospitality acoustic design across London including Mayfair, Soho, Covent Garden, Chelsea, Shoreditch, Notting Hill and the City. Our consultancy also extends to hospitality venues throughout the United Kingdom and internationally. Working as an acoustic architect, we resolve sound within the architecture rather than retrofitting it at the end.
Common questions
What venue teams ask us
Yes, and it is measurable. The largest field study on the subject found that music matched to the brand lifted revenue by 9.1 percent against a generic playlist, while slower tempo lengthened the average meal by close to a quarter, the mechanism behind higher spend per cover.
A hospitality audio consultant defines the sonic strategy for a venue, covering speaker specification, acoustic treatment, zoning, infrastructure and how the system integrates with the interior design. Unlike an equipment supplier, we work alongside the design team from concept stage to ensure audio is resolved as part of the architecture.
AV installation is the physical fitting of equipment. Hospitality acoustic design is the upstream process of understanding the space, the operational brief and the guest experience, then specifying the right system and acoustic approach to achieve the desired result. The installer builds what we specify.
Through discreet acoustic treatment within existing ceiling and wall systems, architectural loudspeakers concealed in ceilings or joinery, more even speaker coverage that reduces the need for volume, and better zoning. None of these interventions need to compromise the interior concept.
Yes. Most venues we work on require independent audio zones. Each zone can be controlled separately for source, volume and scheduling, while the system as a whole remains cohesive. This is essential for venues that shift energy and atmosphere from day to night.
At concept or schematic stage, before ceiling details, services coordination and material finishes are confirmed. Early involvement means speaker positions, cable routes and acoustic treatment can be resolved within the architecture, not retrofitted afterwards.
We model the service arc of the venue and design the zoning, scheduling and system calibration to reflect how the space is used throughout the day. Background music at lunch can transition into a higher energy evening atmosphere without any manual adjustment by staff.
