Sound of the Eye, an artistic collaboration between Danilo Crnogorac (sound design), Milica Šolajić (photography), Igor Andrić (photography), and Nemanja Blagojević (graphic design). The iris is unique in each individual person, same as the fingerprint, and by transforming its lines and patterns from circular into horizontal form, and then into a wave form, one obtains the “sound of the eye,” which is likewise unique in each of us. This experiment and installation includes photographs of eyes made with macro-lenses and shows the procedure of obtaining sound, as well as the possibility of its reproduction. The aim of the project is to show that, by using one sense, one can gain an insight into the features of another – in this case, these senses are hearing and sight. However, it is the eyes we can hear, not the sight: the audio recording of each person lasts 20 seconds and the visitors can recognize the lines of irises by listening to the sound, making a mental connection between the two. Changes in lines influence the range and level of the sound, which is generated by means of sinusoid – the basic wave form with no additional harmonies.
