Aercoustics Engineering Limited (Aercoustics) and Prof. Alis Ekmekci from the University of Toronto are**initiating a research collaboration to investigate wind-induced noise of perforated and slotted panels. Such**panels are very commonly used as architectural features on building facades and can have an adverse impact on**the local noise environment, both for the neighbouring community and for inhabitants of the building itself.**Wind passing through the openings of these panels is known to generate loud tonal noises, which have been**described as howling or humming. This has been observed on buildings such as One World Trade Centre in**New York City and Beetham Tower in Manchester, UK, where noise is reportedly heard up to 300 metres**away. With increased use of these panels by building architects and massive developments like the Agaoglu**Maslak 1453 in Istanbul, Turkey, where nearly every surface is covered in them, understanding the mechanisms**behind noise generation and developing cost-effective means to mitigate it are very valuable. This research will**investigate the interaction of the incident wind with various panel geometries, utilizing methodologies that**facilitate measurements of both noise and flow visualization in the UTIAS anechoic wind tunnel. Results will**provide insight into the underlying mechanisms of noise and the impacts of varying the geometry of the panel**openings. The research is not only important to the public and residents of these buildings, to which the noise is**an annoyance, but to the manufacturers and architects who implement them in designs. Aercoustics is a**specialized acoustic consulting firm that works extensively in the areas of architectural and environmental**noise. Understanding the aeroacoustics of architectural perforated panels through this collaboration will allow**them to provide more valuable and comprehensive services when doing architectural designs. Canada along**with many other countries has established environmental noise guidelines to control noise and ensure**communities and inhabited places are desirable for living. Outcomes of this research can only serve to help**reduce noise pollution and protect the noise environment in our cities.

Aeroprotics Engineering Limited（Aeroprotics）和来自多伦多大学的Alis Ekmekci教授 ** 发起了一项研究合作，以调查穿孔和开槽板的风致噪声。这种 ** 板通常用作建筑物正面的建筑特征，并可能对 ** 当地的噪音环境产生不利影响，无论是对邻近社区还是对建筑物本身的居民。众所周知，风穿过这些面板的开口会产生巨大的音调噪音，这种噪音被描述为嚎叫或嗡嗡声。这种情况在纽约市的世界贸易中心一号大楼和英国曼彻斯特的Beetham Tower等建筑物上都有观察到，据报道，在这些建筑物上，噪音可以在300米外听到。随着建筑师越来越多地使用这些面板，以及土耳其伊斯坦布尔的Agaoglu**Maslak 1453这样的大规模开发项目，几乎每个表面都被覆盖，了解噪音产生背后的机制 ** 并开发具有成本效益的方法来减轻噪音是非常有价值的。本研究将 ** 调查入射风与各种面板几何形状的相互作用，利用方法 ** 促进UTIAS消声风洞中噪声和流动可视化的测量。结果将提供深入了解噪音的基本机制和不同的面板 ** 开口的几何形状的影响。这项研究不仅对这些建筑物的公众和居民很重要，因为噪音是他们的烦恼，而且对在设计中实施这些研究的制造商和建筑师也很重要。Aeroprotics是一家专业的声学咨询公司，在建筑和环境噪声领域开展广泛的工作。通过此次合作，了解建筑穿孔板的气动声学，将使 ** 在进行建筑设计时提供更有价值和全面的服务。加拿大沿着 ** 许多其他国家建立了环境噪音准则，以控制噪音，并确保 ** 社区和居住地适宜居住。本研究的成果将有助于减少噪声污染，保护城市噪声环境。
