So it has fallen to me to discuss ‘sound’, in all its myriad form.

If you are reading this, word for word, you and I are not directly communicating via audible sound, unless someone is reading this to you, or perhaps you are reading aloud.

I recommend reading the rest of the article aloud.

The definition of ‘sound’ is “any audible vibrational disturbance”.

A tree falling in the woods with no creature around to hear it would make no sound. It is non-audible. A random assortment of vibrations would tremor through the ground, perhaps tickling a butterfly in New York to flap its wings.

What about in a vacuum?
Does a mandrake uprooted in space make any sound?

I wonder if the inexorable vibration of the earth grinding on its axle makes a sound.
Of course, in space no one can hear you scream.

Does it seem strange that we cannot hear our giant nuclear radiator in the sky?
The Big Bang surely must have been the epitome of extreme sound. I wonder if there was anyone around to hear it.

There is only sound when there is a witness.
Humans create sound out of occurrences in the world.

There are other forms of sound which do not require audible vibration.

A common slang word and phrase in the UK is ‘sound (as a pound)’.

Regardless of vibrational disturbances emanating from the object (your mate), we can still attribute ‘sound’. Depending on your spiritual inclination, it can be suggested that this is the specific resonance of the human: their vibe, their aura.

Some individuals can be referred to as deep.

Attempting plumbing the depths of these individuals’ psyches could not be fathomed by the deepest submariner.

Naturally, we can go deeper.

A ‘sound’ is an expanse of water, such as a bay or an inlet.
You might have seen the ‘sea shore’.

The alternate meanings of ‘shore’ are ‘to make good’ or ‘to secure something’.
An old connotation of the word ‘sound’ is safety.
This stems from the oldest meaning of the word:

vigour
health
activity

Safe and sound.

In the deep of space the Universe expands, increasing in speed.
A CRT television with no aerial displays static white noise, cosmic background radiation, the fallout from the creation of our Universe.

The (inter)minable vastness of the Universe is the prime example of Deep Sound.

Now, the booming, quaking, plosive, orgasmic, sonorous-ness of all audible sound, having been safely covered, it is imperative to consider other options.

What about non-audible frequencies?

‘Mechanical waves, travelling in solids, liquids and gases.’

These vibrations include infrasound – such deep bass that it is felt rather than heard. Also consider the extremely high pitched frequencies of radio and telecommunications.

People with synaesthesia envision colours from sound.

Light, being a wave and a particle, emits at specific frequencies, processed by the brain to form colour.

There are many different sources, or phenomena that humans cannot interpret.
Our senses are limited.

Humans can only hear sound within a varying range. Light can only be seen within a spectrum.

I wonder at imaging electromagnetic radiation in our mind’s eye.
To see and hear the multitudinous patterns of alpha and gamma rays beaming down from the sky, and the chaotic disharmony of existence.

We concern ourselves with the safety and wellbeing of the Universe, meaning ‘one turn’ deserves another.

It is interesting to me that certain frequencies sound pleasurable.
This can also be said of combinations of colours.

The beating heart of a pregnant mother, acknowledged by babies in the womb, is suggested as the reason we come to appreciate sound.
