" At 3:15 a.m. Wednesday morning, I awoke to the sound. It was slightly different in timbre, with two tones this time. I couldn’t be sure what it was at first, but after a moment I realized it was the Trade Center. Outside it was raining but the trees were calm. I can only imagine at that height the weather is different. I’m sure all of downtown hears this—it’s unmistakable and very chilling. I had to get up and record it. [You can hear it especially well around :20.] It seemed to calm down about 5 a.m."
1 WTC ( One World Trade Center) , the successor to the World Trade Center towers, was nearing completion in 2013, it began to emit a sound “like a train passing by”. Urban legends about the souls of 9/11’s victims soon followed.
Social media was filled with complaints about whistling buildings, and ghost chasing conspiracy theory hunters. So why buildings whistle?
Its general problem which is raised together with high rise buildings. Sometime they whistle. Sometimes it's sounds like spectre. As always science people know how.
This time the staff at Southampton University’s Institute of Sound and Vibration Research say, modern geometries are too complex to pinpoint the exact cause of the whistling, so solutions to whistling are often unique to the building itself. Sometimes using scale models of intended buildings to look for what they call “feedback mechanisms in the vortex-shedding process” could show us how the problem maybe solved.
So the whistling of 1 WTC went away, as the final struts stacked into place. But still let' s hack back to our question and ask science; Why buildings whistle?
