DECIBEL - Main Result
Calculation: Noise Report
DUTCH RULES FOR NOISE CALCULATION.
The calculation is based on "Reken- en meetvoorschrift windturbines", February 2010 The calculation is based on ISO 9613-2 and assumes uniform directional distribution The wind distribution is calculated for the Site center from http://www.mp.nl/rekentool/ Noise values in calculation: All noise values are Lden values

DECIBEL - Assumptions for noise calculation
Calculation: Noise Report
Noise calculation model:
Dutch 2011
Wind speed:
Aggregated
Ground attenuation:
General, Ground factor: 0.5
Meteorological coefficient, C0:
5.0 dB
Type of demand in calculation:
1: WTG noise is compared to demand (DK, DE, SE, NL etc.)
Noise values in calculation:
All noise values are mean values (Lwa) (Normal)
Pure tones:
Pure tone penalty are added to demand: 0.0 dB(A)
Height above ground level, when no value in NSA object:
5.0 m Allow override of model height with height from NSA object
Deviation from "official" noise demands. Negative is more restrictive, positive is less restrictive.:
0.0 dB(A)
