why, what, where and who?

Colours in our visible spectrum are the portion of the Electromagnetic field that our physical receptor (the eye) is able to perceive.

(430THz infrared – 790 ultraviolet THz)


Colours like sounds have a wavelength and a frequency.

Commonly accepted audio spectrum is 20-20k Hz


Commonly accepted voice spectrum is 85 to 180 Hz for male and from 165 to 255 Hz a typical adult female.


Red color for instance has a frequency between 400 and 484 THz.

However, how red is a color red for each one of us?

Here is where perception and conscious experience come in.

Each sound, each color, each stimuli has a specific resonance in each of us that is conditioned by cultural, personal, physiological and environmental and many other factors.

What is ideasthesia? 

from WIKI is defined as a phenomenon in which activations of concepts (inducers) evoke perception-like experiences (concurrents).

The name comes from the Greek idea and aisthesis, meaning “sensing concepts” or “sensing ideas” and is introduced by Danko Nikolić.

(e.g.,color of a number-color of a letter etc..)

What is synesthesia? 

from WIKI is a neurological phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. (e.g.,sound of a color)

What is the difference between these 2 phenomena?

Apparently synesthesia is not supposed to work on a cognitive level.

Among previous studies on this subject the more noticeable for my intent is the one known as “Bouba/Kiki effect”. This effect was first observed by German- American psychologist Wolfgang Köhler in 1929. (Psychology of Gestalt)


In 2001 the experiment was repeated and more than 95% of the people agreed with the names. This suggests that sounds has an important role in the construction of meaning and therefore the language.

In Bouba/Kiki experiment the shapes and the sounds were predefined.

In my experiment I will give the user the possibility to draw a shape according to her/his own perception of the sound.

this will allow the user to have more control and will hopefully trigger factors such as self awareness.

What interests me is exploring the 5% and the nuances in the subjective perception of the same sensorial input (sound, color, meaning) and what this means in terms of self- perception.

I also want to explore how this system could be used in art therapy sessions, and how this could help the user to express him/herself.

Phonetics: the study of the sounds of human speech. It is concerned with the physical properties of speech sounds, their physiological production, acoustic properties, auditory perception, and neurophysiological status.

Semantics: the study of meaning, focused on the relation between signifiers and their denotations (i.e., meaning and literal meaning). It involves words, phrases, symbols and signs.
