UAP/UFO Silence  09/30/20

 

Jack Sliwa- Technologist

     This unnerving but explainable phenomenon has been widely noted across the world for a very long time. There is zero doubt as to its reality. The answer is actually quite simple and has two major parts:

1) Why is the craft itself frequently absolutely silent or emitting an almost indistinguishable hum or buzz?

2) Why does nearby wildlife go silent-presuming it doesn't audibly panic instead?

                                                               Part 1-The Craft Itself

 

   We all know sound can be attenuated-i.e. if you are far away from someone, even in an open space, you can hardly hear them. That is because sound radiates in all directions so by the time it gets to you there simply isn't much sound energy left along the line between you and the speaker which makes it all the way to your ear. Secondly, if someone in a jungle with thick foliage is talking, his/her voice is damped or attenuated by the mass of greenery between you-the remote listener-and the speaker. That is because of sound absorption and multiple sound scattering reflections from the greenery. People already know these things and these are NOT the UAP explanation.

   With a UAP/UFO we bring something new into consideration that people are not familiar with. That is that UAPs have a force-field around their hull AND that force-field is what levitates a hovering UAP. Some have referred to this as an "antigravity" field but for this explanation it doesn't matter how it works- it mainly repels downward the atmosphere and the ground below it. This does NOT require that the UAP's mass or weight is reduced to zero or changes at all-it probably doesn't as deduced by landing marks, tree branches parting and cold downdrafts due to decompression of the air due to the force field experienced around UAPs.

   It turns out, as has been known for a very long time, as a general truth, that sound (acoustic energy) prefers to proceed to travel in air of constant density to minimize reflection. Yes-reflection, reflection as by trying to pass into a higher air density. This property of sound travel applies to solids, liquids and gases and is referred to as acoustic impedance. This simply means the resistance to sound travel in a material. When sound in ANY material goes from Material A into Material B then there is usually a different acoustic impedance in the different new material which means some of the forward-going sound will be back-reflected and some will continue to proceed forward into the new material B. Its the same for the air around the UAP. If the UAP force field causes a significantly lower air pressure nearer and at the UAP than further away (as it clearly appears to do-as would be expected) then you again have an acoustic impedance change and a reflection of some emitted UAP sounds backwards back toward the UAP. i.e. Only some of the sound makes it through the pressure (impedance) discontinuity to the witness. This is no mystery. The severity of the sound drop relates to the severity of the density (pressure) change. Right at the UAP underside the air pressure is likely significantly lower than away from the UAP. There is a reliable equation (see link if interested in details) for this generally known phenomenon but it isn't really necessary to discuss it here. It also applies to medical acoustic imaging per the reference. Keep in mind that it is likely that this sound loss depends on the angle to the craft-any line along a weaker force field will have less sound loss. Also keep in mind that a UAPs power plant and auxiliary power units (if any) are likely near the force field emission zone thus the major sounds are likely damped.

   To get a large sound loss in air (once sound makes it off the UAP surface)  one would need a 10-30X pressure reduction by the force field at the hull surface. I stress that this lowest pressure layer can be fairly thin.

   That is one source of sound loss that depends totally on the pressure delta whose magnitude is only a guess. Note that a reduced pressure near the UAP also makes it easier for the UAP to ignite (activate) the plasma.

   It also turns out there is a second UAP related mechanism at work, one that has also been certified in earthly labs to a lesser but assured degree. If you create a plasma in the atmosphere (like UAPs do) and excite it electrically at audio frequencies (lower than the plasma creation frequency) with changing voltage (say a music recording) you can actually get the plasma to act as an audio speaker. The reverse of this is likely also true-i.e. by applying the appropriate low frequency electrical excitation to the plasma you can damp or even CANCEL some range of sounds that would have otherwise passed through to the witness. It is even conceivable this is used as a silencer or muffler by UAPs. i.e. When the otherwise emitted sound particularly is regular in nature it can easily be cancelled.

   Both of these, individually or together, are certainly lab testable to demonstrate the extent of the sound loss as a function of UAP force-field (the force field and electric field which produce the low pressure region and the impedance related sound dampening, the plasma in that region and the probable additional plasma sound dampening in the plasma).

   It may well be the case that the UAPs sounds still heard are mainly the plasma "speaker mode" as excited by the UAPs electric AC field which indeed is thought to operate at least partially in the audio range and extends somewhat beyond the lowest pressure zone. All of this could proceed in parallel. None of it is unanticipated nor mysterious.

                                               Part 2-The wildlife and ambient sounds going silent

   

    It should be apparent that if the listening witness is actually immersed in part of the UAP/UFO force field or plasma field then they are themselves enveloped in all directions by a sound damping surrounding. An excellent and extreme example is an overhead UAP/UFO where the witness no longer hears the wind blowing through the nearby trees, nearby airplane sounds or some wildlife noises that may still be present.

   Finally, much wildlife probably goes silent out of fear of the UAP sounds, sight and/or electrical/magnetic fields. This is not unlike small birds disappearing and going quiet when an eagle or falcon is around.

   Some partially or fully domesticated pets and cattle or horses do panic and make a lot of noise upon a UAP arriving (or even being nearby-perhaps because they realize they can't run or hide effectively) while some pets crawl under cars and beds and other protective structures. I will leave it to the animal experts to explain those somewhat different animal and pet reactions. They are real and have been observed for a long time.
