Do objects possess unique aural essences that combine to produce the physical sounds we hear? Are these essences a philosophical signifier of their sonic presence?

Unheard is a study situated within a philosophical premise that describes a reality which is imperceptible but intelligible. Every sound is a product of the impact of one surface on the another. But what do objects sound like when they aren’t in contact with other objects and what are the sounds of objects when they are not being defined by their relationship to other objects?

My research navigates the mysteries and realities of the aural essences of my hand. An aural essence, as I define it, is an imperceptible signifier that becomes audible when coupled with the essence of another object. And ‘sound’ happens, when two or more essences combine. 






Aural Essence Derivation Process



To isolate the aural essence of my hand, I first recorded my hand interacting with different objects, surfaces, materials and textures. After this, I recorded an impulse response of the object, which gave me the unique acoustic properties of that object. This technique is commonly used to get the acoustic characteristics of spaces, but I used it for objects.

I wrote a script in python that allowed me to perform a mathematical function called deconvolution - to remove the sound of the surface from the sound of my hand and that surface together – leaving me with the aural essence of my hand.



Wearable Sleeve
I constructed the sleeve with a bone conduction speaker that allows the listener to hear the sounds only when their body is contact with the speaker.



Initial sketches and prototypes of the sleeve. I used a Feather with an Audio Board, a Lithium Polymer Battery and a Bone Conduction Transducer.
