The WELL Building Standard's Sound Concept: What It Requires
The WELL Building Standard is best known for air quality and daylight, which is why people are often surprised to learn it has an entire concept dedicated to acoustics, with a mandatory starting requirement that has nothing to do with panels or products.
Where Sound sits within WELL v2
WELL v2 is structured around ten concepts, covering air, water, nourishment, light, movement, thermal comfort, sound, materials, mind and community. Sound is one of the ten, addressing reverberation, background noise from building services, and speech privacy across a certified building.
The precondition every project has to meet first
Every WELL-certified project must satisfy S01, Sound Mapping, as a precondition before pursuing any further Sound features. This requires the project team to produce an actual sound map of the building, identifying every acoustic zone, every significant noise source, and every noise-sensitive use, before deciding what treatment goes where.
It's a genuinely useful discipline, not just paperwork. A sound map forces the design team to confront where a quiet meeting room sits next to a plant room, or where an open-plan floor backs onto a lift lobby, before those become expensive problems discovered after fit-out.
How this interacts with BS ISO 22955:2021
For UK offices, WELL's Sound concept and BS ISO 22955:2021 are frequently specified together, and for good reason. BS ISO 22955 gives the acoustic design methodology, the activity-based approach and the Class A ceiling coverage figures, while WELL provides the certification framework and points structure that methodology sits inside. One tells you how to design the room; the other tells you how that design counts toward certification.
Who actually needs to care about this
Landlords and developers pursuing WELL certification need the Sound concept addressed from the earliest design stage, not retrofitted. Tenants moving into a WELL-certified or WELL-targeting building will often find acoustic performance already specified into the lease, which changes what a fit-out is allowed to compromise on.
Common questions
Is the Sound concept compulsory for WELL certification? The S01 Sound Mapping precondition is mandatory for every certified project. Further Sound features beyond that are pursued for points, with requirements varying by certification level.
Can an existing, occupied building pursue WELL Sound certification? Yes, WELL applies to existing buildings as well as new construction, with the sound map and any resulting treatment specified around the building as it currently operates.
Finding out if it applies to you
See our guide to office acoustics and BS ISO 22955:2021 or book a free survey to check what your building's certification target actually requires.

From first survey to final finish
One team handles all seven stages, the same way on every project, so you always know what happens next.
A surveyor visits the site, or works from your drawings and photos when a visit isn't practical. Either way, the room, its surfaces and how it is used are recorded before any advice is given.
Reverberation, ambient noise and noise transfer are read against what the space is used for. The findings arrive as a written report with recommendations, yours to keep with no obligation to proceed.
Treatment is modelled against a reverberation target, then drawn up with panel positions, fixings and finishes. Nothing moves forward until you have approved the design.
Every quotation comes with the specification behind it, listing products by type, quantity and finish with costs set out line by line. What is quoted is what the design calls for.
Panels, baffles, ceilings and screens come from our Acoustic Solutions range and are supplied to the approved specification. What arrives on site matches what was designed.
Our own engineers fit to the approved drawings, checking positions and fixings as they go. One team supplies and installs, so nothing is handed between contractors.
Optional: after fit-out the space can be measured again and compared with the original survey, so the improvement is measured rather than assumed. Results are reported against the relevant standards and the written record goes into your building file.
