Restaurant Acoustic Design in United Kingdom — BS 8233:2014 Requirements
Restaurants, cafes, bars, food halls. Typical volume: 200-2,000 m³.
What BS 8233:2014 Requires for a Restaurant in United Kingdom
Regulation: BS 8233:2014 Table 4 — guidance only
RT60 target: ≤ 0.8s
Background noise limit: 45–55 dBA acceptable
How to Calculate BS 8233:2014 Compliance for a Restaurant in United Kingdom
- 1
Identify the applicable United Kingdom standard and target
Look up BS 8233:2014 for restaurant spaces in United Kingdom. The RT60 target is ≤ 0.8s. BS 8233:2014 Table 4 — guidance only.
- 2
Measure or model the room geometry
Record the length, width, and height of the room to calculate the volume. A typical restaurant has a volume of 200-2,000 m³.
- 3
List all surfaces and their absorption coefficients
For each surface (floor, ceiling, walls, windows, doors), find the absorption coefficient at each octave band frequency (125 Hz to 4 kHz) from ISO 354 test data or a materials database.
- 4
Calculate total absorption and apply the Sabine or Eyring equation
Sum all surface absorption values: A = sum of (alpha x area). Then apply T60 = 0.161 x V / A (Sabine) or T60 = -0.161 x V / (S x ln(1 - alpha_avg)) (Eyring). Use Eyring when average alpha exceeds 0.20.
- 5
Compare result against BS 8233:2014 and specify treatment
If the calculated RT60 exceeds the target of ≤ 0.8s, specify additional absorption. Typical treatment cost in United Kingdom is £65–£120/m².
