Restaurant Acoustic Design in Netherlands — NEN 1070:1999 Requirements
Restaurants, cafes, bars, food halls. Typical volume: 200-2,000 m³.
What NEN 1070:1999 Requires for a Restaurant in Netherlands
Regulation: Activiteitenbesluit noise limits
RT60 target: ≤ 0.8s
Background noise limit: 45–55 dBA
Local note: Dutch hospitality sector subject to strict Activiteitenbesluit environmental noise limits.
How to Calculate NEN 1070:1999 Compliance for a Restaurant in Netherlands
- 1
Identify the applicable Netherlands standard and target
Look up NEN 1070:1999 for restaurant spaces in Netherlands. The RT60 target is ≤ 0.8s. Activiteitenbesluit noise limits.
- 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 NEN 1070:1999 and specify treatment
If the calculated RT60 exceeds the target of ≤ 0.8s, specify additional absorption. Typical treatment cost in Netherlands is €60–€120/m².

Frequently Asked Questions
What RT60 does NEN 1070:1999 require for a restaurant in Netherlands?
NEN 1070:1999 requires a reverberation time of ≤ 0.8s for restaurant spaces in Netherlands. Activiteitenbesluit noise limits. Measurement should be performed per ISO 3382-2 methodology.
What is the background noise limit for a restaurant in Netherlands?
The background noise limit is 45–55 dBA under NEN 1070:1999. This typically refers to HVAC and building services noise measured with the room unoccupied.
How much does acoustic treatment cost for a restaurant in Netherlands?
Typical acoustic treatment for a restaurant in Netherlands costs €60–€120/m². Costs vary based on finish quality, room size, and existing conditions.
