The Shape of Sound

The maleus, incus & stapes bones are so small
that they all fit on the face of a penny.

A Little Background on Sound

As you may already know, deep within the human ear are the smallest bones in the body: malleus (mal'-ee-us) or hammer; incus (in-kus) or anvil; stapes (stay-peez) or stirrup. They percuss on delicate auditory membranes in response to sound vibrations in the environment. Perception of sound is a complicated matter involving the fields of physiology, neurology, psychology, and acoustics.  In the human auditory system invisible sound waves become noise that is perceived as language, music, emotions, and memories.

How Does it Work?

Sound waves travel down the ear canal, hit the eardrum which stimulates the vibration of the smallest bones in the body that

The ear has sensory receptors for both sound and balance.

causes a chain of events through a densely anatomically populated area behind the temporal bone culminating in signals sent to the brain via the auditory nerve. After arriving in the brain (very much unlike taking an elevator up a couple of floors, but more like fireworks in the night sky), synapses in various parts of the brain take this info from the outside world and turn it into our auditory perception of the world.

Good Vibes Are For Real

Sound is vibration and vibration affects the physical form. Chanting in the spiritual practice of yoga is thought to influence how the physical and spiritual bodies function. Since these practices have been around for a few millennium, you'd think there must be something to it. Perhaps these yogis fine tuned their senses so that they could feel the effects of sounds on their bodies. The following video backs up what I'm trying to explain here. Just watch how the sand dances and then settles into various patterns depending on the tone of the resonance. If we surround ourselves with or create certain vocal frequencies why wouldn't our bodies shift in response to this?

Visual Patterns of Audio Frequencies

Please watch this astounding video. It depicts the patterns formed by varying tones of sound and it blows my mind. Honestly, after seeing this video I had to come up with some legit anatomical reason for sharing it with you, hence this blog post. The comments on Youtube are wonderfully nerdy. It makes me so happy to know that some folks use math to quantify beauty such as this. I'm fulfilled by knowing that beauty simply exists whether or not we know how or why.

See you in the clinic,
Dana
