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.”

The Death roll verses the Pitchpole

I like yachts.  Love messing around in them like my dad loved airports. It is that spirit of movement and sense of adventure they embody. The smell of salt water, the tinkle of the halyards against masts set the pulse racing. Not that I am sailor I got my first job in my 20’s and spend my salary on a sailing dingy - a Topper. That year I lived and worked in Cowes, which is quite a sailing Mecca. I seem to capsize in front of the posh sailing club every time I had to turn direction. Do you remember learning to ride a bike? For me it was riding in straight lines that came first. Every time I had to take a bend, off I came with knees, elbows and hands bearing the brunt of my mistakes. Eventually, I learned to corners on bikes. Unfortunately, in sailing I never mastered certain manoeuvres.  The two main reasons for my capsizing have wonderful names.  One is called the Death roll and the other is called the Pitchpole. 

“Death roll

This is an interesting setup to the broach.  Sailing downwind can cause an oscillation of the boat rocking back and forth.  An inexperienced helmsman will tend to try to correct this by steering away from the "roll" but this will cause it to get worse.  Once the roll gets to strong the boat broaches.

Pitchpole

This is a different sort of hydrodynamic problem.  The boat is going at a certain speed and the sails are under enough pressure to maintain the speed.  When the hull suddenly slows down the sail "keeps going" and the boat pitches over the bow in a spectacular summersault.  This is usually because you're racing down the back of a wave and when your bow hits the next wave it slows down abruptly.”

When in either position and moving fast  I invariably managed to capsize the boat. I didn't let it stop me sailing. One colleague from work who foolishly came sailing with me abandoned ship after the third capsize.  I watched him flee for shore as if his life depended on it. 

I didn't belong to any sailing club and I never minded the Hurrah Henrys looking on with their irritating nasal laughter, canvas shoes and wine glasses. It was the wind, waves and adventure that had me mesmerised. There is a feeling being really in the moment that confirms you're really alive not spectating or waiting for life to begin. My Topper taught me that.  I learned to right the boat again with remorseless painful practice. It's not the end of the world to find yourself in the water with the sail on your head. Sometimes, you have to work out which way is up and down. You can be that disorientated. Breathe as much air as you can before working on getting the boat upright. Before you can get moving again you will need to find your bearings and get above water.

At times life will do that.  It will take the feet from under you. Don't waste time worrying about who is watching you. Focus on deep breaths and conserving your energy for the task in hand. Wind direction changes, waves can come in all sizes and at times your skills don't quite meet the challenge. There is no shame in that. You're not responsible for what comes your way. Only for how you choose to respond to it. We need to remember that! Don't waste time on being humiliated by life. Instead, fill your days with times worth remembering.

"It is not death that a man should fear, but he should fear never beginning to live."

Art in Valetta, all shapes and sizes

Entered the St James Cavalier Centre and was rather confused by an art exhibit.  But to be honest, I am no artist so take my opinions with a pinch of salt.  So here goes...

I found the rather long explanation on video by the artist unconvincing.  I reckon if you have to emphasis simplicity and witter on about the hidden meaning in each brush stroke you are stretching the margins of artistic endeavour a little too thin.  Looking carefully at each one I searched for what I could find and came up with very little.

Moving onto the galleries upstairs I really enjoyed the photo display on exhibition.  I urge all who haven't been to check it out before it goes.  To entice you I am showing a few with my own captions (apologies to wonderful photographers whose work this really is).

Running down sand dunes with kites is something only kids think of doing - but we all should.

Children make such wonderful subjects of photography.

Real beauty cuts across all cultures and boundaries.

Some photographs are so good they become paintings in our heads.

You can never have enough colours.

A whole new meaning to the expression, "The train was packed this morning!"

A new way to use old bottle tops and carry it off with style.

Making art is about getting down and personal with your creation and becoming part of the joy of it.

Transporting nuclear warheads in an ecologically sound manner. (only joking)

Why are you looking at me? it is purely circumstantial evidence, I am totally innocent.

Leaving the galleries I am confronted with the beautiful square outside and wonder why someone thought it a good idea to put a pillar with what looks like part of someone's colon on top!  (see white monstrosity on black stone underneath) There are some modern art sculptures that seem criminal in their ugliness.  The surrounding beauty serves to only stress its hideousness.

On leaving Valetta through its main gates I check out an exhibition in the Parliament Building on diversity and loved the Maltese children's take on this topic.  Their pure hearted expressions won me over completely and filled me with hope for the future of us all.

A Love Affair

I have a deep and abiding love of libraries.  My father had his own extensive collection of books and I can remember lifting a green book from his shelves unable to read at that early stage but burning with curiosity.  Many libraries often began as private collections.  For example Pierpoint Morgan's Library in New York was made by the financier Pierpoint Morgan (1837-1913) during the years of 1902 - 1906.  Eleven years after his death his son J P Morgan converted it into a public institution.  It is startlingly beautiful.

So lovely to have this resource available to the public, mind you they have to pay 20 dollars to get in.

You don't have to pay to get into the New York Public library.  It was created from the private libraries of Astor, Lenox and Tilden being amalgamated into a new library in 1989.  The new library opened in its present position in 1911.  The building itself is grand enough.

 But it is the Rose Main Reading Room which lies inside that makes my heart beat, despite never having had the delight of visiting it.

So during a visit to my son in Manchester, this summer, I took advantage of both the huge bookshops and lovely libraries available.  Rylands library in Manchester is a Gothic structure strangely imposing from the outside.

Despite its deceptively aged exterior look it was constructed and took ten years to build, opening in 1900.  It was built in memory of Manchester's first millionaire John Ryland (1801-1888) by his widow.  It has a somber beauty to it.

With strange dark corners and bookcases that hint of mysterious contents.  The Rylands Library contains a fragment of St John's gospel, only 3.5 by 2.5 inches in Greek dating from the second or early third century. Recently, one team of researchers stated that they may have found the oldest-known copy of a gospel within the papyrus-wrapped mask of mummy. When wrapping mummies scraps of papyrus from all kinds of sources were used including it turns out stories from the the Greek poet Homer to mundane business/personal letters etc The writing on this scrap is thought to be a part of the Gospel of Mark and dates back to around 90 A.D.—decades earlier than any other previously discovered gospel text.

But by far my favourite library is the Public library of Manchester.  The Public Libraries Act was passed in 1850 and in response Manchester was the first local authority to provide a free lending and reference library.  The official opening of the public library was attended by Charles Dickens in 1852. The present existing public library was opened in 1934 and was based on the Pantheon in Rome.  It is wonderfully impressive from the exterior.

Having gone through much restoration the inside is equally delightful.

High above this dome there are inscribed the memorable words from the bible,

“

Wisdom is the principal thing; therefore get wisdom, and with all thy getting get understanding. Exalt her and she shall promote thee; she shall bring thee to honour when thou dost embrace her, she shall give of thine head an ornament of grace, a crown of glory she shall deliver to thee.Proverbs 4:7”

What a wonderful reminder of what libraries should be all about.  I found the library full of people from all walks of life.  There were media booths, archives, maps, computers, coffee shop, study booths and books in all languages.  I felt strangely touched watching a Chinese couple choosing from the extensive Chinese bookshelves.  How wonderful to find yourself in a foreign country and yet discover your culture respected and acknowledged so openly.  A down and out character with holes in his socks and no shoes sat in comfort staring at the ceiling but enjoying the warmth and company around him.

Moving to a different level of the library I discovered the music section with pianos, drum kits, mixing decks and other musical instruments all available to members of the public. This is the Henry Watson Music Library. Henry Watson(1846-1911) was originally an errand boy in a Blackburn music store and by six had taught himself the dulcimer.  By ten he was a session musician and by fourteen he was touring the county as an accompanist to an antislavery show.  At 18 he was part of a booming instrument repair business.  He went on to get a doctorate from Cambridge and was a prolific composer and arranger.  He founded a library of 15,000 rare scores, 300 instruments and 200, 000 volumes of printed music.  Despite being completely self taught this errand boy ended up a professor of the Manchester College of Music.  He would have been delighted, as I was, to come upon an African teenager with headphones playing the set of drums with intensity and concentration in a library donated by him.  A famous composer was curious about a detail in the horn part of the slow movement in Beethoven's 4th Symphony.  Fortunately this library contains the 1st edition of the full score and band parts.  He was able to find the notes never performed in modern editions but there faithfully recorded as it was originally played.

If ever you are in Manchester check out this amazing building and soak up its wonderful atmosphere.
