Residents living around One WTC have been reporting strange sounds coming from the building, which is still under construction, on windy nights for a little over a year now.
A local news article published by PIX11 on December 3rd, 2013 points out an important anecdote, "Animal New York reports that residents began hearing the strange howling, whistling sounds during Hurricane Sandy last year."
The most recent reports came in late November, early December. New York City's Port Authority has weighed in on the subject:
NEW YORK (PIX11) - The Port Authority, which owns the World Trade Center site, says the noise is probably just the wind and far from paranormal.

A pattern is being noticed, "When it gets windy in Lower Manhattan, residents report hearing a strange, high-pitched, ghostly sound from the top of One World Trade Center."
"The Huffington Post - Kenny Cummings, who lives a few blocks away from One WTC, told Tribeca Citizen in an email that he first noticed the eerie whistling during Hurricane Sandy, and most recently heard the noise early on November 27:

"Builders of pipe organs have included stops intended to imitate the sound and timbre of the aeolian harp. German builders were the first to include such a stop from the 1820s. The Aeolian Harp stop is not a harp—it is simply a rank of pipes using a low wind pressure and voiced to imitate the sound of the real instrument. It is therefore classified as a 'string' stop. These stops are amongst the softest found on pipe organs."
Seamless Transition: Introduction to INFRASOUND
In the Google Book 'Sonic Warefare: Sound, Affect, and the Ecology of Fear' by Steve Goodman, the author goes into a little detail about Infrasound and some of the first experimental research on the subject:
"After accidentally experiencing nausea in his lab with his research team (owing to unintended vibrations leaking from industrial machinery), Gavreau became obsessed by harnessing infrasonic resonance to design sonic weapons (usually in the form of huge pipe devices.)
After another experiment, caught in the vibratory 'envelope of death,' Gavreau and team allegedly suffered sustained internal spasms as their organs hit critical resonance frequencies. It was these strange physiological anomalies, generated by inaudible vibrations, that inspired his research into infrasonic acoustic guns.
The key notion was that directional inaudible sound at certain resonant frequencies 'acting directly on the body' could produce 'intense friction between internal organs, resulting in a severe irritation of nerve endings.'"
"Gavreau started researching the phenomenon by holding vibrating pipes next to clueless assistants. We'll never know what excuse he used when they turned around and asked him why their ears were bleeding, but one way or another Gavreau soon realized that a vibrating pipe of the right length and girth can cause a number of unpleasant effects ranging from mild irritation to serious pain.
What he had discovered...was infrasound. It's noise at a low enough frequency that you don't consciously hear it, but your ears still sense it. The process of receiving sensory input without your conscious mind understanding where it's coming from wreaks havoc with your emotions. Specifically, researchers found that sounds between 7 and 19 Hz it could induce fear, dread or panic.
They did an experiment where acoustic scientists sneaked in low frequency sounds at a live concert. Since scientists love nothing more than inducing feelings of fear and terror in unsuspecting citizens, most of the concert goers had no idea what was going on. As a result one minute they were enjoying some sweet tunes while the next a feeling of dread invaded their hearts, crushing all hope and happiness. At the end of the experiment approximately 22 percent of the people involved in the experiment reported feelings of unexplainable dread, chills and depression when infrasound was blasted into the crowd.
...mother nature is creating this type of low frequency vibration all the time. Volcanos, earthquakes, strong ocean waves and even winds hitting the hillside in just the right spot can create infrasound. Even animals can create it, and tigers are particularly well known as a source. The frequency of a tiger's roar is around 18Hz -- right in that range we mentioned earlier."
Science Daily Quick Quote on InfraSound:
The Cracked article concludes with a relevant statement, which can be extended to the WTC One 'chilling noises' phenomena produced by windy nights, "So now we have a phenomenon that occurs in nature, is invisible, is imperceptible on a conscious level, but can spontaneously make you feel irrational fear, even if you're sitting in an empty room."
"...infrasound has long been a respected area of study in meteorology, where the frequencies range from as low as one cycle in 1000 seconds up to a few cycles per second. Large arrays of infrasound microphones detect low frequencies originating in atmospheric effects, meteorites, supersonic aircraft, explosions etc. There is also a worldwide system of about 60 infrasound arrays, which are part of the monitoring for the Nuclear Test Ban Treaty (P.5).
2.1 Noise and sound. Noise and sound are physically the same, differences arising in their acoustic quality as perceived by listeners. This leads to a definition of noise as undesired sound, whilst physically both noise and sound are similar acoustic waves, carried on oscillating particles in the air. Sound is detected by the ear in a mechanical process, which converts the sound waves to vibrations within the ear (P.6).
2.2 Frequency and wavelength. The frequency of a sound is the number of oscillations which occur per second (Hz), denoted, for example, as 100Hz. Sound travels in air at about 340ms-1, but this velocity varies slightly with temperature (P.6).
2.4 Low frequency noise and infrasound. The frequency range of infrasound is normally taken to be below 20Hz and that of audible noise from 20Hz to 20,000Hz. However, frequencies below 20Hz are audible, illustrating that there is some lack of clarity in the interpretations of infrasonic and audible noise. Although audibility remains below 20Hz, tonality is lost below 16-18Hz, thus losing a key element of perception. Low frequency noise spans the infrasonic and audible ranges and may be considered as the range from about 10Hz to 200Hz (P.7).
2.6 Infrasound. There are a number of misconceptions about infrasound, such as that infrasound is not audible. As will be shown later, frequencies down to a few hertz are audible at high enough levels. Sometimes, although infrasound is audible, it is not recognised as a sound and there is uncertainty over the detection mechanism. Very low frequency infrasound, from one cycle in, say 1000 seconds (0.001Hz) to several cycles a second are produced by meteorological and similar effects and, having been present during all of our evolution, are not a hazard to us (P.8)."
S0, putting together all the pieces of the puzzle - Eyes open, no fear:
The World Health Organization is one of the bodies which recognizes the special place of low frequency noise as an environmental problem. Its publication on Community Noise (Berglund et al., 2000) makes a number of references to low frequency noise, some of which are as follows:
• " It should be noted that low frequency noise, for example, from ventilation systems can disturb rest and sleep even at low sound levels"
• "For noise with a large proportion of low frequency sounds a still lower guideline (than 30dBA) is recommended"
• "It should be noted that a large proportion of low frequency components in a noise may increase considerably the adverse effects on health"
• "The evidence on low frequency noise is sufficiently strong to warrant immediate concern" (P.5)
