Tribeca Citizen recently shared a video that captures One World Trade Center making a high-pitched wailing noise, and while it's certainly annoying for the neighbors, the Port Authority says the sound is caused by large open shafts in the still under-construction tower. Thus, when it's complete, the sound should stop. But that may not be true; it could be coming from the louvres or the spire, which in that case, it would have to be retrofitted after completion to eliminate the sound. [Gizmodo; Tribeca Citizen]
