In the Buenos Aires neighborhood of Núñez, an unusual phenomenon has become the main enemy of tranquility. Every time the wind blows a little stronger, an entire building begins to emit a deafening whistle that invades the daily lives of those who live nearby. This is the Núñez Business Center, located at 7200 Avenida del Libertador, a modern complex that, paradoxically, ended up being the source of an unexpected problem.

The noise began to be noticed in the middle of last year, when the cladding work on the structure was completed. Since then, neighbors like Dardo have lived with the uncertainty of not knowing when the whistling will start again. "At first, you think it's a car alarm or some isolated sound, but then you realize it's coming from the building," he said in an interview with Arriba Argentinos.

According to his account, the sound appears mainly on windy days and resembles a wind instrument at full volume. Architect Andrés Bordagaray explained in a recent interview the reasons behind the disturbing phenomenon: "It's an effect produced by aerodynamic issues or structural vibration. Due to certain regulatory changes and with increasingly taller buildings, these consequences are caused."

The proximity to the river and the lack of natural barriers worsen the situation. The wind circulates strongly and, when it hits certain profiles or cavities in the façade, it creates what Bordagaray described as "a kind of throat" that amplifies the sound.

The solution, however, is not simple. "Once it's built, it's difficult to modify it. A detailed study would be needed to determine exactly what causes it, but in general, some type of aerodynamic complement, such as a spoiler or deflectors, is required to divert the wind and cut the vibration," the specialist indicated.

The company that developed the complex, Raxa, has not yet publicly announced what measures it will take to solve the problem. Meanwhile, the owners' association and the neighbors in the area face a dilemma that grows with every gust. "You start to despair and see what can be done," he admitted
