Now that there are over 6 billion smartphones in use around the world the young children of today are even starting to use the phones when they are pre-teenagers and it is reasonable to expect that the issues of PVS will increase as the genetics of humanity becomes universally fed on digital impulses and electromagnetic pulses at close range delivered by high-tech wireless devices. Beyond the actual physical oscillations of the phone which is what most research into PVS focuses there is also the radiation, heat and electromagnetism that can cause changes to cellular walls and create heat and emissions on the atomic level that have yet to be fully understood and declarations of absolute safety cannot be issued, instead the global economy that revolves around wireless devices and the transmission of media has declared this a non-issue and has attempted to reassure any fears and silence any detractors of their agenda who question the benign nature of the technology they use, often used for propaganda and marketing of a consumer agenda.
Brain chemistry is another key component in determining the cause and likelihood of PVS to strike someone. Neural transmitters that perform similar tasks across the species will have minute variations among individuals; humans cover the spectrum of smart and stupid, compassionate and evil, fat and thin and just as we all react differently with the introduction of certain chemical substances or under different external environmental cues there will be differences in how the compound use of vibrating phones reacts in each individual. People who are genetically prone to anxiety may be at a higher risk to PVS as may people with underlying addictive personalities who have convoluted cellular leanings based on reward and deprivation.
Vibration settings and sound frequency settings of a phone are also implicated; most cell phones will emit tones for rings or vibrations within the range of 950 Hz to 6100 Hz – the same frequencies that have a predisposition to actually shock the auditory system. This is why we respond to the vibration or ring in that we are attempting to damper the blast effect experienced even at lower volumes the frequency of vibration causes a shock and when we are blasted by our cell phone vibrations and rings and alarms and alerts, especially if we get very frequent notifications or calls, we are doing nothing less than literally jolting the auditory cortex into submission to be even more sensitive to these frequencies.
The range of frequencies of between 1000 Hz through 6000 Hz are more difficult for humans to pinpoint through spatial navigation which is why many phone users who hear their phone ringing or vibrating will have a difficult time locating their device if it is not in their pocket. The elicited frequencies from the device do not allow a rapid and precise geolocation of the device and this may cause a conditioned neural imprint to occur over extended use of the phone that is emitting these ringing frequencies and the combined vibrations. This conditioning of a brain can leave it sensitized beyond normal to these sounds.
The vibratory oscillations of most smart phones and iPhones are in the range of 120 Hz and 200 Hz and when a phone is set to vibrate at the arrival of a wireless trigger signifying a call or text message and the phone is in a users pocket or on their person they will feel the vibration via your skin. The sensitive skin receptors and neural transmitters send signals to the brain that there is an alert or incoming communication on the phone. This, of course, is the proper design function taking place; we want to be notified of the incoming communication hence we have programmed the device to vibrate to notify us of the reception. The receptors, especially with repetitive vibrations, become conditioned and the brain chemistry instills importance to the messages and amplifies the focus placed on receiving the vibrations as the brain begins placing higher importance on the phone and anticipation of reward becomes paramount to the extent that the skin and brain receptors will conspire to activate the individual to check their phone.
The skin receptors that are altered by the continued vibrations become sensitized to any contact that is within the range of frequencies of the ringtone or the vibration setting patterns and it is theorized that due to this over-sensitization that even clothing could trigger a phantom vibration if the clothing closely mimics the frequency of the phone. Someone may lean against something or have a wind ruffle their coat or even a car stereo in the vicinity of the subject could cause micro vibrations in similar wavelengths that a person might suddenly detect a phantom ring on their person even if they do not have their device with them.
