Missing Wavelengths?

The sound of the sea soothes. Its rhythm a mighty solace. When calm its frequency is slower (1/10) than the beat of the human heart. No wonder being beside it is such a source of comfort. Just like the baby in the womb is soothed by the thump, thump of their mother’s heart we too are comforted by the sea’s rhythm. We are bathed in such a noise from conception but it is only when we develop sensory organs do we properly hear them. Mind you, even without working ears the deaf can feel the vibration of sound through bone/floorboards/a balloon held in their hands so perhaps even before audio organs were fully functioning perhaps we felt the vibration in the womb of the nearby heart. As the ears developed in the womb the baby grows to recognise the mother’s voice and is found to respond to certain external music.

Sight too is developed in the womb and, like sound, we humans have a limited spectrum in which we can operate. Bees can see the magnetic field, bats can use sound in order to navigate. Visible light is our piece of the electromagnetic spectrum. We may feel the heat of an infrared wavelength or suffer the sunburn of UV rays or even use devices to enable us to hear radio waves or microwaves but the visible spectrum is where our eyes excel.  Everything we see is due to this tiny fraction of the whole spectrum. If the whole of the electromagnetic spectrum was laid out before us as 100 toilet rolls (with each roll having 1000 sheets) we can only see three and a half sheets (0.0035%).

We pride our ability to see our surroundings, perceive and then understand. We see the rain clouds, understand we may need our umbrella and take it with us. So closely entwined is this with understanding that we even use the phrase “I see” interchangeably with “I understand”. To see or perceive to take in information, process it and make use of that knowledge is almost too seamless for us to even notice. 

Humans are sufficiently adaptable to allow one sense to help another. Some blind people have taught themselves to use echolocation to understand their surroundings via sound waves. These waves can produce reflections which tell them how close obstacles and structures are. This ability can be taught relatively quickly especially to children. Because we as sighted individuals learn about our environments using vision, we often do not readily perceive echoes from nearby objects. However, with training, even sighted individuals with normal hearing can learn to avoid obstacles using only sound, showing that echolocation is a general human ability.

Our intelligence has permitted us to make use of other areas of the electromagnetic spectrum. Our WiFi, mobile phones, radios etc have helped us to make inroads into other sheets of those rolls of toilet paper we spoke of earlier. X-rays in medicine give us the ability not to see our surroundings but our internal body structures.  Magnetic resonance imaging (MRI) is another type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body.  Our ingenuity has allowed us to glimpse how other creatures hear and see. Elephants can hear very low-frequency sounds, we cannot hear, through their huge feet and can pick up such invaluable information as the early low-frequency rumbles of an approaching tsunami or earthquake. Dolphins can hear a much broader range of frequencies than we humans.  Our ears can only pick up frequencies from 20 Hz to 20 kHz whereas dolphins can hear from 20 to 150 kHz. Their hearing is up to 7 times more sensitive than the human ear.  Perversely, the humble moth has the best hearing of any creature (The greater wax moth's hearing goes up to about 300 kilohertz). Eagles have better eyesight than humans. They can see eight times further than us and see shades of colour we cannot.  They can even see ultraviolet light which helps them see bodily traces left by their prey. 

We may have extended our ability to function in other spaces of the full sound spectrum or electromagnetic spectrum but there is a range (a bit like the range of musical instrument) that we are designed to see and hear with our own faculties. Even our eyesight was designed to see not only close-up but also the distant horizon. Perhaps to distinguish close up edible seeds from toxic ones or to discern prey or spot predators approaching from afar. If we deny ourselves the full panorama of life around us we can damage our eyesight. So, too much screen time sacrifices our farsighted abilities.

The frequencies we hear and see have consequences in our brain. Not only in how we interpret but what feelings they engender. Beauty in nature awakens emotions within us not just factual realities. A wonderful piece of music can elevate our spirit or soothe our distress. If we could understand the lasting impact what we see and hear has on human beings we might be more refined about what we tune our ears to or focus our vision on.

The senses are doorways to mind, spirit and body. They can be extended and developed or curtailed and deformed. Our daily choices decide what benefits or deficits we experience therefrom. To be in nature surrounded by its sounds is a source of healing. Music does indeed soothe a troubled breast. This world we were born into is a feast for us both acoustically and visually. But when depressed we can sometimes not even see the beauty around us.

Spirituality is the ability to walk the path that nurtures your real progress. Our senses guide us but it is in understanding what we hear and see that our real development takes place. If we choose not to investigate the truth with heart and mind then we impede our progress and that of the society around us. It’s as if our physical senses are merely portals to investigate reality. The real magic happens when and how all that is processed and acted upon.

If we see the suffering of others we have some choices.

1.   Avoid - make sure we are not exposed to such sights again. news/disaster/coverage/tragic events. Akin to the ostrich hiding its head in the sand. Or choosing to See no evil, hear no evil or see no evil.

2.     Cynical self-interest - Feel no sympathy with those ‘others’. As long as one’s own family is fine why be perturbed by those of others. Train yourself to be selective about who you will respond to, particularly those in despair or need.

3.  Feel helpless - Watch so much of the news, what’s going wrong with this world that you become angry and feel both despair and hopelessness.

None of these choices ends well.  We do need to become informed of what is happening in the world good and bad. When suffering and injustice occurs it helps to take some steps to remedy it. It could be small but taking action puts power back in your hands. Inaction fuels your own helplessness. Your actions, however seemingly futile, can inspire others. If mistakes happen you can learn to adjust and correct. Progress can be made through action.  From the good you observe in this world best practice can be absorbed. Inspirational accounts (factual and informed) can give powerful examples of how others have already perceived a problem/injustice/wrong/suffering and acted. They fan your flame to take action as a response to what comes. Not reinforce acquiescence and acceptance of the status quo however damaging.

If life can be likened to the electromagnetic spectrum we need to recognize the source is abundant. We are bathed in this constant pouring out of energy from above. It fuels our food and fills our bellies. It warms our body and enables our eyes to see. All of that is designed to benefit the human race and all the creatures that share this planet with us. To be selfish with resources, money or acquisitions is the opposite of this demonstrated abundance. To abuse, this planet and people for individual gain is to reduce one’s spirit to the lowest level of existence.  We can bury ourselves in materialism to such a degree that we no longer see the sun or feel its heat. We have burrowed into dark places that take us down not up.

The electromagnetic spectrum and the wavelengths of sound demonstrate our limited ability to even see or hear what is actually out there. The fact that other creatures can hear and see more than we can is a mighty reminder that this world is not just for us human beings. It is filled with living entities who are designed like us to inhabit this wondrous planet. They hear and see things beyond our reckoning. Some can even see the polarization of light. Many can use the Earth’s magnetic field to orientate themselves on this sphere. If this is so, is it not cavalier to pollute this world so beautifully designed for all species, not just the human race.

The sad thing about this preferring ourselves over all living creatures, our nation over other nations, our tribe over the next valley’s tribe or even our family over our neighbours is that this process of self-interest causes even further fractioning. Until the very members of our own families can become ‘others’.

Hearing is indeed selective! If this world was designed to function in harmony then just like music we need all the various notes and resonate frequencies to come together.  To recognize that each of us is only a part of the whole. The principle of oneness must be owned if we are to turn the clock on this ‘otherness’. 

If oneness of humanity is the pivot then the further we move from this principle (that point) the more unbalanced that moment becomes. The larger the distance the bigger the destabilization that takes place.

Once we have a vision of the world as one then the model of the human body illustrates that there are many different organs with remarkably varied functions within it. The unity it exhibits underscores the need to grasp the whole. Every part working together for the health of the human body. Fuelled by a mighty muscle, the heart, beating the lifeblood through intricate tubing but coordinated by a brain that feels, senses and responds to your needs, urgent or long term. If this is the model then humanity has to be seen as one system. No part can be allowed to become infected, malnourished or damaged without fundamental injury to the whole. Every action whether it be marshalling immune defences or controlling temperature has the good of the whole as it’s overarching goal.

Our upset at the chaos and turmoil around us is not a thing to be ignored or suppressed or be distracted from. When we see the suffering of others and feel distress it is because you know at a vital level there are no ‘others’. You subconsciously feel united with this world you live in. You may not see every wavelength or hear every frequency but you feel your connectedness. Celebrate this intuitive knowledge and hold it close.

Receptivity, hearing loss and dancing hairs in your ear

Hearing is such a wonderful sense. We forget how unique it is. Until we lose it. I have several family members whose hearing is severely damaged because of exposure to loud noises. In those days farmers didn't use ear muffs so machinery and the firing of shotguns did irreparable damage to their hearing. The effects of this often only show themselves in later years. It is particularly hard to learn these vital lessons when the effects are not immediate. My eldest brother returned from a punk rock concert forty years ago, where he had been standing a little too close to the wall of enormous speakers at the event. For three days he had a ringing sound in both ears and it lasted long enough that he thought permanent damage had been done - it wasn't, he was lucky. Who would've thought years later that the very headphones we use to protect the ears of workers are now damaging the ears of our young who blast themselves incessantly with load music. 

We lose your hearing in many different ways and for many different reasons. Conductive hearing loss is when there is a problem in the transmission of sound to the inner ear. Wax and ear infection or middle ear ossicles (when the tiny bones transmitting the vibrations on the ear drum can no longer do their job) can all contribute to this form of hearing loss.  It is sobering to think that the ear drum which is the fragile link between the outer ear and the middle ear is only 10mm in diameter.  However small that appears, the drum thickness is tinier still at only 0.08 mm.  It can be easily ruptured by excessive noise, pressure or physical trauma.  For those among us who insist on jamming ear buds in their ear to clean them - remember a typical sheet of paper is thicker than your ear drum.  Hearing is a sensitive business from every point of view.

This fragility is matched by the bones, the ossicles, which are on the other side of the ear drum resting against it to pick up the vibrations of the drum. The ossicles are the three tiniest bones in the whole body and form the coupling between the vibration of the eardrum and the forces exerted on the oval window of the inner ear.  This system is connected to the cochlea which looks a bit like a shell.  It has tiny hairs inside that vibrate and transmit the sound to our nerves in the brain.  Usually, age related hearing is when these tiny hairs become damaged and die off.  Our high frequency hair cells die off before low frequency ones and we lose some every year.  If you want to see what these hairs look like, check this out.  You need to press the video button to actual see the hair dance to music.

If you have ever wondered how it sounds to have a cochlea implant you can experience it here (click on link below and listen to both tracks).  I must admit I was disappointed with the results but then my expectations were high.  If you cannot hear at all then this must seem like unbelievable progress.  For Beethoven losing his hearing must have been a torment almost impossible to endure.

To see how wonderful these implants can be for those experiencing deafness this young boy's face says it all.

It is startling to discover that the young generally are more receptive.  They literally hear a much broader frequency range than older people.  Another fascinating feature is that if you lost 166,000 photoreceptors in a retina of your eye you would not be able to see a patch in your vision smaller than the moon’s image.  Everything else would look okay. However, destruction of 166,000 hair cells in your ear would result in disequilibrium and profound deafness.  

We need to respect this sense so much more than we do at present.  Think of an inertial guidance system, an acoustic amplifier and a frequency analyser inside the volume of a marble and be impressed.  Hair cells detect motions of atomic dimensions and respond 100,000 times per second.  

Remember that over time, repeated exposure to loud noise and music can cause hearing loss. To put that in perspective we need to know a few facts.

1. The decibel (dB) is a unit to measure the level of sound.
2. The softest sound that some humans can hear is 20 dB or lower.
3. Normal talking is 40 dB to 60 dB.
4. A clap of thunder from a nearby storm (120 dB) or a gunshot (140-190 dB, depending on weapon), can both cause immediate damage.
5. A rock concert is between 110 dB and 120 dB, and can be as high as 140 dB right in front of the speakers.
6. When listening to a personal music system with stock earphones at a maximum volume, the sound generated can reach a level of over 100 dBA, loud enough to begin causing permanent damage after just 15 minutes per day!

But it is the effect that this sense can have on our spirit that surprises me constantly.  Just as we can damage this amazing organ with abuse, when used appropriately it be transformative.  I love these quotes on what music can bring to all our lives.

“..although sounds are but vibrations in the air which affect the ear's auditory nerve, and these vibrations are but chance phenomena carried along through the air, even so, see how they move the heart. A wondrous melody is wings for the spirit, and maketh the soul to tremble for joy.”

`Abdu’l-Bahá

“Music produces a kind of pleasure which human nature cannot do without.”
