The reading before the money
Given: A square, a Saturday in June, three stages and 15,000 visitorsSolved for: The margin at every facade, the layout that passes, and what else can kill the permit
The loud day: three stages, every facade.
What a festival organiser receives before booking a square: whether the permit's sound limit can be met there and with which layout, how many loud days the place has left, what else the city has on that day, and the clock of the application, in six answers.
This sample is the reading before the money: the place, the date, the stages and the hours are given, and the margin at every dwelling's facade and the grounds that bind are solved for, months before the application, when the organiser can still move a stage, cut an hour or change the date. It is sold to festival organisers.
01 · What was asked
Can my festival's sound limit be met on this square, with which layout, and what else can kill the permit?
The festival
An organiser has Location A in mind for 19 June 2027: three stages from 12:00 to 23:00 and 15,000 visitors at the peak. Before the square is booked and the artists are signed, can the limit be met at the dwellings around it, with which layout, and what else stands in the way?
02 · What was read
One square, six answers
The square as it stands: the stages come on, the facades colour by their margin, one stage turns and another is trimmed, and the red recedes.
01 · The stages on the square
12 facades
The square as it stands: 10 buildings around it in three dimensions, the facades of the dwellings within reach of the stages, each at its storey, and an audience zone in front of each of the 3 stages.
- 15,000 visitors at the peak
- Stages 12:00–23:00
- Sourced and graded in the report
02 · The sound at every facade
−4 dB
In the first layout the facade that binds stands at 89 dB(C) against a limit of 85; 4 of the 12 facades are over it.
- At the desks 81 · 78 · 78 dB(A)
- Limit 85 dB(C) at the facade
- Sourced and graded in the report
03 · The layout that passes
+1 dB
Turn stage 1 by 30° and take stage 3 down 4 dB, and the facade that binds is +1 dB inside the limit; stage 1's first zone gives up 900 places.
- Stage 1 turned 30°
- Stage 3 down 4 dB
- Sourced and graded in the report
04 · The event days left
4 of 12
Location A has 4 of its 12 event days left this year for an event of this size, and 2 more are applied for; the others are held by a concert · a market. Its budget of loud days is 3, and how many of them are used is not yet known, because no public record says which permitted day is loud.
- a concert
- a market
- Loud days: 3
- Sourced and graded in the report
05 · The day's load
4 within reach
On 19 June 2027 the city has 1 match, 2 concerts, 1 demonstration within reach, and it names its capacity on such a day as a ground for the permit.
- 1 match
- 2 concerts
- 1 demonstration
- Sourced and graded in the report
06 · The clock
27 February 2027
The application is due on 27 February 2027 at the latest, 16 weeks before the day; of the 3 structures that need an advice, 1 has none yet: the tent.
- the main stage
- the tent
- the light tower
- Sourced and graded in the report
The reading is the pre-check; the study filed with the application is the acoustician's.
03 · What it changed
Every change, read again
It is sold to festival organisers. Today each change of plan is a new quotation and the answer comes after the application; here the organiser moves a stage, swaps a tent, cuts an hour or the date, and reads the risk again before the money goes.
