PULSE wind turbine sound power<br />
determination according <strong>to</strong> IEC 61400–11<br />
International <strong>standard</strong> IEC 61400-11 demands consistency and accuracy<br />
in the measurement of wind turbine <strong>noise</strong>, using quality equipment with<br />
calibration that is traceable <strong>to</strong> national institutes.<br />
Our easy-<strong>to</strong>-use, complete test system minimises the headaches of following<br />
the pro<strong>to</strong>cols required by the <strong>standard</strong>. The <strong>standard</strong>’s exacting<br />
methodology is simplified thanks <strong>to</strong> an intuitive user-interface that covers<br />
the measurement, analysis and reporting of complex acoustic emissions.<br />
Typical measurement with the actual<br />
indication of the number of <strong>measurements</strong><br />
per wind bin.<br />
With this solution, wind turbine manufacturers can define acoustic emission<br />
performance, wind turbine opera<strong>to</strong>rs can check the expected acoustic emission<br />
performance of new or refurbished units, and planners and consultants<br />
can calibrate or validate their calculated environmental <strong>noise</strong> maps.<br />
With Brüel & Kjær’s unrivalled back<strong>up</strong> service including accredited calibration,<br />
you can trace the validity of <strong>your</strong> <strong>measurements</strong> <strong>to</strong> the appropriate national<br />
<strong>standard</strong>s body.<br />
