death of Miss Cilia

[AntonioLao]

In addition to being an organ that detect body position and balance, maintaining body equilibrium; the function of the inner ear in humans is to act as a transducer by changing one type of waves into another type such as longitudinal sound waves into transverse electric waves to the brain. In order to do this, the 3 smallest bones in the human body: the hammer, the anvil, and the stirrup vibrate to and fro against the elastic oval window of the cochlea. In turn it vibrates the fluid in the inner ear. The vibrations of this endolymph fluid excite little hairs of varying length called cilia. These can vary between 2 to 20 microns with average diameter of ¼ micron. The varying frequencies of the fluid resonate with the varying lengths of the cilia sending nerve impulse to the auditory nerves which relays electric information to the brain. This mechano-sono-electro and non-magneto process establishes the human faculty of hearing.

However, attending loud rock concerts, many enthusiastic concert-goers often complain of ringing in their ears after leaving the concerts. The ringing is a result of the death of Miss Cilia. If the sound is extremely loud and goes on for a prolonged period the overloaded resonating cilia often end up damaged or destroyed. The ringing sensation is an ominous warning that the cilia are dying. However, the ringing usually disappears the day after the concert, but permanent damage has already been done, because those hairy cilia will never grow back. The effect of such hearing loss can take many years and only becomes apparent by repeated exposure to loud sounds and those lingering, annoying ringing thereafter.

Exactly the reason why hearing protection is recommended or mandatory in many employment situations and recreational pursuits, the use of firearms being one such. Horses, on the other hand, do not pose an auditory risk, save when one neighs in your ear, lol, but it is a wise precaution to wear a certified riding helmet with full harness, rather than a 'hunting cap with chin strap.'

But how can we protect against all the infrasonic or ultrasonic sounds that we cannot hear? They do carry very small amounts of energy and wherever and whenever these are accumulated, they can be just as destructive. Fortunately, the cilia must vary in the order of Planck length.

Our body will alert us to the presence of sound by other physical means, as per the highlighted section that follows. In some environments, appropriate hearing protection may be considered. In other cases, avoidance or limited exposure may be the only solution. For myself, I cannot abide the sound of many common appliances and so do not own a clothes dryer or vacuum. Previously owned these appliances and found them irritating in the extreme. One reason I have selected my current employment venue is for the air quality and a sound level that is only bothersome during the brief interval that the cleaners are running the floor washer and buffer. Occupational Health and Safety permits us to leave the area if we find the noise or fumes too overbearing, as on occasion (as when waxing) they can be.

Some common bio-effects of electromagnetic or other non-lethal weapons include effects to the human central nervous system resulting in physical pain, difficulty breathing, vertigo, nausea, disorientation, or other systemic discomfort. Interference with breathing poses the most significant, potentially lethal results. Light and repetitive visual signals can induce epileptic seizures (see Bucha effect). Vection and motion sickness can also occur. Cavitation, which affects gas nuclei in human tissue, and heating can result from exposure to ultrasound and can cause damage to tissue and organs.

Studies have found that exposure to high intensity ultrasound at frequencies from 700 kHz to 3.6 MHz can cause lung and intestinal damage in mice. Heart rate patterns following vibroacoustic stimulation has resulted in serious negative consequences such as arterial flutter and bradycardia. [8] [9]

Researchers have concluded that generating pain through the auditory system using high intensity sound resulted in a high risk of permanent hearing damage. Organizations in a research program which included the Naval Submarine Medical Research Laboratory (Groton, Connecticut), Navy Experimental Diving Unit (Panama City, Florida), SCC San Diego, Navy Medical Research and Development Command (Bethesda, Maryland), Underwater Sound Reference Detachment of Naval Undersea Warfare Center (Orlando, Florida), Applied Research Laboratories: University of Texas at Austin, Applied Physics Laboratory: University of Washington, Institute for Sensory Research: Syracuse University, Georgia Institute of Technology, Emory University, Boston University, University of Vermont, Applied Physics Laboratory, Johns Hopkins University, Jet Propulsion Laboratory, University of Rochester, University of Minnesota, University of Illinois, Loyola University, and the State University of New York at Buffalo, involved high intensity audible sound experiments on human subjects.

The extra-aural (unrelated to hearing) bioeffects on various internal organs and the central nervous system included auditory shifts, vibrotactile sensitivity change, muscle contraction, cardiovascular function change, central nervous system effects, vestibular (inner ear) effects, and chest wall/lung tissue effects. Researchers found that low frequency sonar exposure could result in significant cavitations, hypothermia, and tissue shearing. No follow on experiments were recommended. Tests performed on mice show the threshold for both lung and liver damage occurs at about 184 dB. Damage increases rapidly as intensity is increased.

Noise-induced neurologic disturbances in humans exposed to continuous low frequency tones for durations longer than 15 minutes has involved in some cases the development of immediate and long term problems affecting brain tissue. The symptoms resembled those of individuals who had suffered minor head injuries. One theory for a causal mechanism is that the prolonged sound exposure resulted in enough mechanical strain to brain tissue to induce an encephalopathy.[10] “Project Pandora” conducted by the Walter Reed Army Institute of Research, WRAIR, included externally induced auditory input from pulsed microwave audiograms of words or oral sounds which create the effect of hearing voices that are not a part of the recipients own thought processes.

I have a slight problem distinguishing the different meanings of these two phrases: "Action speaks louder than words" and "you don't need to shout, I can hear you just fine."

'Action speaks louder than words, but not nearly as often,' is a quote attributed to Mark Twain.

The easiest way to begin to explain the meaning would be by another quote from the same author.

“There are basically two types of people. People who accomplish things,(action) and people who claim to have accomplished things.(Words to such effect.)

The first group is less crowded.”

Your second example is not attributed to any particular author, yet is a phrase commonly used when we restate the obvious to one who has (in their opinion) already made it clear that the parties communicating are speaking from the same premise and within the same framework.

Redundancy is absolutely necessary in communication, as words are subject to much ambiguity in their use and interpretation.

To this effect, we may state, and restate a premise, until we are certain that we are clear and in agreement on the meaning intended and interpreted.

Were it possible to make all communications so abundantly transparent, there would be little need for our legal system, as all transgressions would be apparent, and remedies could be applied accordingly.

The ambiguities of language shall keep the lawyers gainfully employed for eternity, in my humble opinion, no matter that one might wish it otherwise.

'Right' and 'wrong' are but our own interpretations and conceptions of 'what is'.

Likewise, it is absolutely necessary in designing relational or object-oriented databases in order to extend into multidimensional networks like the internet.

Pragmatic redundancy consists of an accessible water storage tank under a floor grate, and living within two miles of the Yukon River. A propane cook-stove that the top burners will still operate even without the electricity that sparks the oven element. A gravity feed, highly efficient oil stove for heat, with a top surface that can be used for heating/cooking and a wood burning stove as back-up, with a cooking surface top as well.

Which may seem redundant until you have experienced a power outage that lasts more than a few hours in winter temperatures of -40C. A few years ago, such occurred and the power was out for 18 hours. Oh yes, and plastic water lines, that have more potential for expansion in the event of freezing, than metal plumbing....

Does this duplicity apply to the Arabic tradition of having multiple numbers of wives? The same question applies for the desire of having two cars, two homes, two kids, two toothbrushes, two eyes, two ears, two arms, two legs, etc. But not two hearts, this is the reason why the human heart must be a director, only one for each person.
