Brief the acoustics before the design begins.
Turn the room types in your building into a clear early-stage acoustic requirement schedule, ready to hand to the design team.
Watch a building become a brief.
A fictional school, pulled apart storey by storey. Each room type lifts out and shows its target, then the targets assemble into the document. Click a room to read its section.
A school, stacked as it would be built.
Classroom / teaching space · 6 rooms of this type
Sample standard and figure for a fictional building. A real brief names the standard that applies to your use, size band and region.
Evidence to plan for
- That the target is carried forward from this brief
- Who confirms it: a measurement, a model or manufacturer data
- The occupied condition the target is checked under
Interfaces to coordinate
- Finishes: is the ceiling acoustically load-bearing for this target?
- Building services: has ventilation noise been confirmed?
- Occupancy: is the real operating condition the one checked?
Look at each room type

Fictional example: Marlowe Lane Primary School. Sample figures set in advance, view only, for illustration. Not for design use.
One schedule the whole design team can work from.
One section per room type
Ten identical classrooms are one section; classrooms, a hall and offices are three. The brief follows the way your building is actually made up.
A target where one is sourced, an honest gap where it is not
Where no confirmed figure exists for a use and region, the brief says so and points you to your local building code. It never fills the gap with a guess.
Evidence to plan for, written down early
Who confirms the target, at which project stage, and under what occupancy condition, so it is not left until practical completion.
Interfaces for the other disciplines
Questions for the AV, finishes and building-services teams whose decisions the target depends on.
A document the design team can open and print
A clear, printable requirement schedule you can hand over before the design begins.
Four steps.
- 1
List your room types
One row for each distinct kind of room in the building.
- 2
Say what each is for
Choose the use, the region and, if you know it, a rough size band.
- 3
The brief is built for you
It is assembled on our server for your account, with a section for every room type.
- 4
Hand it to the design team
Print it or save it as a PDF and make it part of the project brief.
What each room type gets.
The standard and target
The standard that applies to your intended use in your region, with the reverberation target it sets, where a sourced figure exists.
Evidence to plan for
What you will later need to show: who confirms the target, at which project stage, and under what occupancy condition.
Interfaces to coordinate
Questions for the AV, finishes and building-services teams whose decisions the target depends on.
Sold separately, £75 per room type.
Ordering opens soon, once our professional indemnity insurance is in place.
Questions
Is this a calculation of my rooms?
No. It is a requirement schedule for before a room is designed. No room geometry is assessed and no reverberation time is worked out. For a calculated result against a designed room, see Echo and Studio.
What happens when there is no figure for my use and region?
The brief says the target is not yet confirmed for that combination and points you to your local building code. The Other / mixed use option records the use so the target can be confirmed as the design develops.
Who can build a brief?
Brief Builder is sold separately at £75 per room type, and ordering opens soon. Without it you can look at the fictional worked example above, which is view only and cannot be exported.
I bought a brief earlier. Can I still open it?
Yes. The link in your order confirmation email still opens your brief.
Can I keep a copy?
Yes. Once your brief is built you can print it, save it as a PDF or download a copy.
Its limits
The brief is an indicative design guide only. It is not a measurement, a certification or a guarantee that a design will meet a target, and it is not a substitute for a consultant where one is required.
It is a requirement schedule, not a calculation. No room geometry is assessed. The size bands are rough indications used only to pick a figure where a standard changes with room size; they are not your room's size. The building and figures in the worked example are fictional and for illustration only, and the 3D view is an illustration.
