What is BS EN 61400-13:2011?

The International Electrotechnical Commission (IEC) developed the BS EN 61400-13:2011 standard to provide guidance for the measurement and assessment of wind turbines. This standard focuses on acoustic noise emissions, ensuring that wind turbines do not cause excessive disturbance to nearby residents.

Noise Emission Measurement

The standard provides specific guidelines for the measurement of noise emitted by wind turbines during operation. It outlines the instruments, procedures, and methodologies necessary for accurate and reliable noise measurements. By adhering to these guidelines, manufacturers can ensure that their wind turbines meet the noise emission limits set forth in the standard.

Noise Assessment and Verification

In addition to measurement techniques, BS EN 61400-13:2011 also contains provisions for assessing and verifying the noise performance of wind turbines. This includes evaluating noise emissions at various distances from the turbine, determining sound power levels, and analyzing frequency spectra. By conducting these assessments, wind farm developers can determine the potential impact of their projects on surrounding communities.

Importance of Compliance

Compliance with BS EN 61400-13:2011 is crucial for both wind turbine manufacturers and wind farm developers. By meeting the noise emission requirements outlined in the standard, manufacturers can demonstrate that their turbines are environmentally friendly and socially responsible. Wind farm developers can use compliance as a selling point when obtaining permits and addressing concerns from local residents.
