1 Introduction This document summarizes the acoustic emission characteristics of the 1.6-100 with Low Noise Trailing Edge (LNTE) wind turbine for normal operation, including calculated apparent sound power levels LWA,k, as well as uncertainty levels associated with the apparent sound power levels, tonal audibility, and calculated third octave band apparent sound power level.

All provided sound power levels are A-weighted.

GE continuously verifies specifications with measurements, including those performed by independent institutes. If a wind turbine noise performance test is carried out, it needs to be done in accordance with the regulations of the international standard IEC 61400-11, ed. 2.1: 2006 and Machine Noise Performance Test document.

2 Normal Operation Calculated Apparent Sound Power Level The apparent sound power levels LWA,k are initially calculated as a function of the hub height wind speed vHH. The corresponding wind speeds v10m at 10 m height above ground level have been evaluated assuming a logarithmic wind profile. In this case a surface roughness of z0ref = 0.05 m has been used, which is representative of average terrain conditions.

The calculated apparent sound power levels LWA,k and the associated octave-band spectra are given in Table 1 and Table 2 for two different hub heights. The values are provided as mean levels as a function of v10m for Normal Operation (NO) over cut-in to cut-out wind speed range. The uncertainties for octave sound power levels are generally higher than for total sound power levels. Guidance is given in IEC 61400-11, Annex D.

Table 2: Normal Operation Calculated Apparent Sound Power Level, 1.6-100 with LNTE with 96 m hub height as a function of 10 m wind speed (z0ref = 0.05 m), the octave band spectra are for information only

At 10 m wind speeds lower than 5 m/s the sound power levels decreases, and may get so low that the wind turbine noise becomes indistinguishable from the background noise. For a conservative calculation the data at 5 m/s may be used.

For 10 m wind speeds above 10 m/s, the wind turbine has reached rated power and the blade pitch regulation acts in a way that tends to decrease the noise levels. For a conservative calculation the data at 10 m/s may be used.

The highest normal operation calculated apparent sound power level for the 1.6-100 with LNTE is LWA,k = 103.0 dB.





3 Uncertainty Levels

The apparent sound power levels given above are calculated mean levels. If a wind turbine noise performance test is carried out, it needs to be done in accordance with the regulations of the international standard IEC 61400-11, ed. 2.1: 2006. Uncertainty levels associated with measurements are described in IEC/TS 61400-14.

Per IEC/TS 61400-14, LWAd is the maximum apparent sound power level for 95 % confidence level resulting from n measurements performed according to IEC 61400-11 standard: LWad = LWA + K, where LWA is the mean apparent sound power level from IEC 61400-11 testing reports and K = 1.645 σT.

The testing standard deviation values σT, σR and σP for measured apparent sound power level are described by IEC/TS 61400-14, where σT is the total standard deviation, σP is the standard deviation for product variation and σR is the standard deviation for test reproducibility.

Assuming σR < 0.8 dB and σP < 0.8 dB as typical values leads to a calculated K < 2 dB for 95 % confidence level.

4 Tonal Audibility

The tonal audibility ( La,k), when measured in accordance with the IEC 61400-11 standard, for the GE’s 1.6-100 with LNTE is less than or equal to 2 dB.

5 IEC 61400-11 and IEC/TS 61400-14 Terminology

LWA,K is wind turbine apparent sound power level (referenced to 10-12W) measured with A-weighting as function of reference wind speed v10m. Derived from multiple measurement reports per IEC 61400-11, it is considered as a mean value σP is the product variation i.e. the 1.6-100 with LNTE unit-to-unit product variation; typically < 0.8 dB σR is the overall measurement testing reproducibility as defined per IEC 61400-11; typically < 0.8 dB with adequate measurement conditions and sufficient amount of data samples σT is the total standard deviation combining both σP and σR K = 1.645 σT is defined per IEC/TS 61400-14 for 95 % confidence level R0 is the ground measuring distance from the wind turbine tower axis per IEC 61400-11, which shall equal the hub height plus half the rotor diameter

La, k is the tonal audibility according to IEC 61400-11, described as potentially audible narrow band sound

The tables in Annex I are showing the 1/3rd octave band values for different hub heights in different wind speeds.
