A possible generator of "strange sounds"

William C. Treurniet, February, 2012

Summary. A number of reports have appeared concerning strange sounds that sometimes continue for hours and are hard to localize. This article proposes that some of these sounds are generated by a novel sound generator developed for military applications. An earlier investigation strongly suggested that a new technology is under development that can cause plasma balls or orbs to appear at a distant location. This same technology might be used to construct a sound generator and resonator at a remote location in the sky. The shape of an unexplained aerial object photographed over Russia is suggested as a model for the sound generator. Two video recordings of strange sounds were analyzed to obtain their fundamental frequencies, and these help to determine that the source resonators were about 13 and 15.5 m long. Further, assuming that the cessation of the sounds coincided with a flash of light in each video, the sources were approximately 2.3 and 3.4 km away from the observers.

Introduction

The UK MoD wrote a summary report in 2000 expressing its interest in a technology which creates plasma balls at a distant location. In a previous article, I presented arguments that some orb sightings in 2011 could be the result of such a research program. The sighting locations suggested that a number of countries such as the UK, Italy, and the USA are involved in the research. That the technology required to create orbs at a distance is not available in the public domain is not surprising if it is the subject of military research. Perhaps such technology is even based on a new physics (e.g., van Vlaenderen, 2008, Cetin BAL, 2005), some consequences of which are described by Morgan in his presention of Tom Bearden's work. According to Bearden, the physics of scalar electromagnetism allows energy to be pulled from the vacuum at a distant location, and this knowledge has been used to make new offensive and defensive weapons. Tests of such weapons may be responsible for the unexplained plasma ball structures that have been reported.

Might auditory effects also be produced with the same technology? In particular, a number of recordings published on You Tube demonstrate a phenomenon of strange sounds being heard around the world. These sounds may persist for hours but are difficult to localize. Nevertheless, observers tend to look to the sky for the source. Perhaps such sounds are artificially generated by using this technology to make a resonator of some kind, then to excite the air inside it with pulses of energy. That this might be possible is suggested by Bearden's discussion of the nature of a Tesla dome. This is an EM "force field" that is supposedly able to stop a projectile in flight. A possible demonstration of such technology might have been caught in July, 2011, by a low-light still camera at the Canada-France-Hawaii Telescope complex on Mauna Kea mountain. A video of snapshots taken every 30 seconds shows a spherical bubble of light gradually growing in size. Figure 1 shows a frame from the video. About a month later, a similar sight was photographed near Beijing. Perhaps the technology used to make a Tesla dome can also construct the resonant cavity of a sound generator.

Analysis

Some properties of such a resonator were estimated from information in two videos of strange sounds. One is the video of a sound heard in Florida in March, 2011, and the other is a video of a sound heard in Minnesota in September, 2011. The sound in each video ends shortly after a bright flash of light in the sky. In each case, the flash of light and analysis of the sound can give us information about the size of the sound resonator and the distance from the observer.

If we assume that the flash signaled the termination of the sound at the source, we can calculate the distance to the source. In the Florida video, the sound faded away about 10 sec after the flash of light. In the Minnesota video, the sound ended about 6.8 sec after the light flash. Since sound travels at approximately 340 m/sec, the generators of the sounds would have been about 3.4 km and 2.3 km away from the observers, respectively.

If the generator is an open cylinder air column, the fundamental frequency of the resonator (F0) is related to the resonator size (L) and the speed of sound (Vsound). Specifically, F0=Vsound/2L. The value of F0 can be estimated from a spectrogram of the sound, and we can then calculate the length L of the resonator cavity.

In Figure 2 (left panel), the overall spectrum of the Florida sound indicates that it has a low-pass bandwidth less than 550 Hz. It appears noise-like within that band, but it does have a harmonic structure. An F0 of 11 Hz approximately fits the pattern of harmonics displayed in the figure. Slightly more than half of the harmonics were present. For an F0 of 11 Hz, the length of the resonant cavity would be 340/22= 15.45 m.

The spectrum of the Minnesota sound in the right panel of Figure 2 has a lower dominant frequency, and the low-pass bandwidth is about 100 Hz. Again, a harmonic structure appears to be present. In this case, an F0 of 13 Hz best fits the pattern of harmonics in the spectrogram. For this F0 of 13 Hz, the length of the resonant cavity would be 340/26= 13.08 m.

In both cases, even and odd harmonics are present. This means that the resonator cavity was not closed, and justifies the use of the formula for the open cyclinder air column.

Discussion

The calculations suggest that the lengths of the resonant cavities of the two sound sources were about 13 and 15 m, respectively. Do we have any indication of the shape of the sound generator? We know from the earlier investigation that a new technology appears to exist that can create plasma balls or orbs. If we assume that a similar technology was used to create the presumed Tesla dome in Figure 1, the technology also appears capable of creating a spherical shell. By coincidence, a Russian UFO sighting in December, 2011, may have given us the shape of the sound generator. Figure 3 shows an object from the video of the event that combines these two elements; that is, it consists of an orb and what may be a spherical shell around the orb.

In such a generator model, the sound exciter would be the orb at the center of the spherical shell, and the length of the resonant cavity would be equal to the diameter of the shell. The impermeable vibrating shell might then behave like a spherical resonator [1, 2] and transmit the energy to the air outside the shell. Changing the output frequency would be accomplished by varying both the diameter of the shell and the frequency of excitation coming from the central orb. Figure 3 shows that the width of the orb is approximately 1/16 the diameter of the sphere. So if a structure as shown in Figure 3 generated the Florida and Minnesota sounds, it was approximately 13-15 m in diameter, and the diameter of the central orb was somewhat less than 1 m.

In calculating the source distance, it was assumed that the light flash coincided with the cessation of the sound. Does the sound generator model based on the object in Figure 3 allow us to speculate on the reason for the flash? Perhaps the off switch caused something equivalent to a discharge over a spark gap. The resulting burst of broadband energy might have been sufficient to briefly but dramatically increase the size of the central orb.
