(Corrigendum)Wind turbines - Part 11: Acoustic noise measurement techniques
Wind turbines - Part 11: Acoustic noise measurement techniques
This document presents measurement procedures that enable noise emissions of a wind turbine to be characterised. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine, in order to avoid errors due to sound propagation, but far away enough to allow for the finite source size. The procedures described are different in some respects from those that would be adopted for noise assessment in community noise studies. They are intended to facilitate characterisation of wind turbine noise with respect to a range of wind speeds and directions. Standardisation of measurement procedures will also facilitate comparisons between different wind turbines. The procedures present methodologies that will enable the noise emissions of a single wind turbine to be characterised in a consistent and accurate manner. These procedures include the following: - location of acoustic measurement positions; - requirements for the acquisition of acoustic, meteorological, and associated wind turbine operational data; - analysis of the data obtained and the content for the data report; and - definition of specific acoustic emission parameters, and associated descriptors which are used for making environmental assessments. This International Standard is not restricted to wind turbines of a particular size or type. The procedures described in this standard allow for the thorough description of the noise emission from a wind turbine. A method for small wind turbines is described in Annex F.

La norme EN 61400-11:2013/A1:2018/AC:2019-11, intitulée "Turbines éoliennes - Partie 11 : Techniques de mesure du bruit acoustique", fournit un cadre essentiel pour la mesure des émissions sonores des éoliennes. Son champ d'application est particulièrement pertinent, car il détaille des procédures de mesure qui permettent de caractériser de manière précise le bruit émis par ces machines. Parmi ses forces, la norme se distingue par sa méthodologie claire et les exigences précises qu'elle établit concernant l'emplacement des positions de mesure acoustique et l'acquisition de données acoustiques, météorologiques et opérationnelles relatives à la turbine éolienne. Cela garantit que les évaluations de bruit se déroulent dans des conditions optimales, réduisant ainsi les erreurs liées à la propagation du son et facilitant une comparaison cohérente entre différentes éoliennes. De plus, les procédures décrites dans cette norme permettent d'évaluer le bruit des éoliennes en tenant compte d'une variété de vitesses et de directions du vent, ce qui est crucial pour une évaluation environnementale précise. L'inclusion d'une méthode spécifique pour les petites éoliennes dans l'annexe F élargit également la pertinence de cette norme à une gamme plus diversifiée de types et de tailles de turbines. Ainsi, la normalisation des procédures de mesure promue par cette norme est d'une grande importance pour les acteurs du secteur éolien. Elle permet non seulement une caractérisation efficace du bruit émis, mais également une mise en œuvre harmonisée des pratiques de mesure, contribuant ainsi à une meilleure acceptabilité sociale des projets éoliens et à une réduction des nuisances sonores pour les communautés environnantes.
EN 61400-11:2013/A1:2018/AC:2019-11に関するこの標準化文書は、風力タービンの音響ノイズ測定技術に関する非常に重要なガイドラインを提供しています。この標準は風力タービンのノイズ排出を特定し、評価するための測定手順を示しています。特に、機械の近くで音響測定を行うことで、音の伝播による誤差を回避しつつ、有限の音源サイズに配慮した適切な手法を用いています。 この標準の強みは、異なる風速や風向における風力タービンノイズの特性化を容易にすることです。さらに、測定手法の標準化は異なる風力タービン間での比較を促進し、結果的に業界全体の透明性を高めることに貢献します。また、音響測定位置の選定、音響および気象データの取得要件、取得データの分析、環境評価用の特定の音響排出パラメータの定義など、多様な方法論を提供しています。 この国際標準は、特定のサイズやタイプの風力タービンに限定されず、幅広い適用範囲を持っています。これにより、風力タービンからのノイズ排出を詳細に説明する手法を提供し、小型風力タービンについては付属文書Fでの具体的な手法も含まれています。このように、EN 61400-11は風力業界における音響評価の標準化において非常に重要な役割を果たしています。
Die Norm EN 61400-11:2013/A1:2018/AC:2019-11 befasst sich mit den Akustikmessverfahren von Windkraftanlagen und ist von entscheidender Bedeutung für die Standardisierung der Geräuschausstoßmessungen, die von diesen Anlagen erzeugt werden. Ihr Umfang umfasst die Spezifizierung von Messverfahren, die dazu dienen, die Geräuschemissionen einer Windkraftanlage präzise zu charakterisieren. Hierbei wird darauf geachtet, dass die Messmethoden an Standorten durchgeführt werden, die nah genug an der Maschine liegen, um Fehler durch Schallausbreitung zu vermeiden, dabei jedoch weit genug entfernt sind, um die endliche Quelle in der Bewertung zu berücksichtigen. Ein hervorstechendes Merkmal dieser Norm ist die Neubewertung der Verfahren im Vergleich zu den standardmäßigen Bewertungsmethoden, die in Studien zur Gemeinschaftsgeräuschmessung angewandt werden. Dies ist besonders vorteilhaft, da die spezifischen Anforderungen an die Charakterisierung von Windturbinengeräuschen bei unterschiedlichen Windgeschwindigkeiten und -richtungen berücksichtigt werden. Die Standardisierung der Messverfahren ermöglicht auch relevante Vergleiche zwischen verschiedenen Windkraftanlagen und unterstützt somit die Entwicklung und Auswahl effizienter und umweltfreundlicher Technologien. Die beschriebenen Verfahren geben eine präzise Methode an, um die Geräuschemissionen einer einzelnen Windkraftanlage konsistent und genau zu erfassen. Dies schließt Anforderungen für den Standort der akustischen Messpositionen, die Erfassung von akustischen, meteorologischen und betrieblichen Daten sowie die Analyse der gewonnenen Daten und den Inhalt des Datenberichts ein. Ebenso werden spezifische akustische Emissionsparameter und deren Beschreibungen definiert, die für Umweltbewertungen verwendet werden. Die Norm ist nicht auf Windkraftanlagen eines bestimmten Typs oder einer bestimmten Größe beschränkt, was ihre Anwendung umfangreicher und universeller macht. Insbesondere im Anhang F wird eine Methode für kleine Windkraftanlagen beschrieben, was die Relevanz der Norm für verschiedene Marktsegmente betont. Insgesamt bietet die EN 61400-11:2013/A1:2018/AC:2019-11 eine umfassende Grundlage für die akustische Bewertung von Windkraftanlagen und trägt wesentlich zur Verbesserung der Umweltverträglichkeit und Akzeptanz von Windenergieprojekten bei.
The standard EN 61400-11:2013/A1:2018/AC:2019-11 serves as a comprehensive guide for the measurement of acoustic noise emissions from wind turbines. Its primary scope encompasses the establishment of measurement procedures that accurately characterize the acoustic noise generated by wind turbines. This is particularly crucial in environments close to the machine to prevent inaccuracies stemming from sound propagation, while still being distanced adequately to account for the finite size of the noise source. One of the standout strengths of this standard is its emphasis on standardization in noise measurement methodologies, allowing for valid comparisons across different types of wind turbines. Each procedure outlined is tailored not only to maintain consistency but also to ensure precision across various wind speeds and directions, providing stakeholders with relevant data under differing operational conditions. It is noteworthy that the standard differentiates itself from traditional community noise assessments, focusing specifically on the unique acoustic characteristics of wind turbines. Additionally, the document includes detailed requirements for the acquisition of relevant acoustic and meteorological data, and provides guidance on the following critical aspects: strategic locations for acoustic measurement positions, comprehensive analysis of collected data, and standardized content formatting for reporting. Furthermore, it defines specific acoustic emission parameters vital for environmental assessments, ensuring a thorough approach to wind turbine noise characterization. The international applicability of the standard, being not limited to specific turbine sizes or types, enhances its relevance and usability across the industry, catering to a broad spectrum of wind turbine technologies. Moreover, the inclusion of an annex detailing methods for small wind turbines enhances its practicality for different stakeholders in the wind energy field. In summary, EN 61400-11:2013/A1:2018/AC:2019-11 represents a significant advancement in the standardization of noise measurement techniques for wind turbines. Its comprehensive procedures facilitate precise characterization and consistent reporting, ultimately contributing to more informed environmental assessments and improved understanding of wind turbine noise emissions.
