Description

Phased microphone arrays have become a well-established tool for performing aeroacoustic measurements in wind tunnels (both open-jet and closed-section), flying aircraft, and engine test beds. This paper provides a review of the most well-known and state-of-the-art acoustic imaging methods and recommendations on when to use them. Several exemplary results showing the performance of most methods in aeroacoustic applications are included. This manuscript provides a general introduction to aeroacoustic measurements for non-experienced microphone-array users as well as a broad overview for general aeroacoustic experts.

Translated Description (Arabic)

أصبحت مصفوفات الميكروفون المرحلية أداة راسخة لإجراء قياسات صوتية هوائية في أنفاق الرياح (النفاثة المفتوحة والمغلقة)، والطائرات الطائرة، وأسرة اختبار المحرك. تقدم هذه الورقة مراجعة لأكثر طرق التصوير الصوتي شهرة وأحدثها وتوصيات حول وقت استخدامها. يتم تضمين العديد من النتائج النموذجية التي توضح أداء معظم الطرق في التطبيقات الصوتية الهوائية. توفر هذه المخطوطة مقدمة عامة للقياسات الصوتية الهوائية لمستخدمي مصفوفة الميكروفون غير ذوي الخبرة بالإضافة إلى نظرة عامة واسعة لخبراء الصوتيات الهوائية العامة.

Translated Description (French)

Les réseaux de microphones à commande de phase sont devenus un outil bien établi pour effectuer des mesures aéroacoustiques dans les souffleries (à jet ouvert et à section fermée), les avions volants et les bancs d'essai des moteurs. Cet article fournit un examen des méthodes d'imagerie acoustique les plus connues et les plus récentes, ainsi que des recommandations sur le moment de les utiliser. Plusieurs résultats exemplaires montrant les performances de la plupart des méthodes dans les applications aéroacoustiques sont inclus. Ce manuscrit fournit une introduction générale aux mesures aéroacoustiques pour les utilisateurs de microphones non expérimentés ainsi qu'un large aperçu pour les experts aéroacoustiques généraux.

Translated Description (Spanish)

Las matrices de micrófonos por fases se han convertido en una herramienta bien establecida para realizar mediciones aeroacústicas en túneles de viento (tanto de chorro abierto como de sección cerrada), aviones voladores y bancos de pruebas de motores. Este documento proporciona una revisión de los métodos de imagen acústica más conocidos y de vanguardia, y recomendaciones sobre cuándo usarlos. Se incluyen varios resultados ejemplares que muestran el rendimiento de la mayoría de los métodos en aplicaciones aeroacústicas. Este manuscrito proporciona una introducción general a las mediciones aeroacústicas para usuarios no experimentados de la matriz de micrófonos, así como una amplia descripción general para expertos aeroacústicos en general.
