Sinutu is a sound visualization, based on the contrast between day and night, this project aims to hear and feel everyday sounds with our eyes by visualizing the sounds created by nature and people. Sounds were recorded in line with the data collected by the answers given by 6 people with different social statuses, according to their own experiences and auditory perceptions. Sinutu is divided into two parts these are day and night, circles representing time, also warm colors represent day and cold colors represent night. The amount, thickness and proximity to the center of the circles change according to the level of the sounds, and the movements of the circles become the reflections of the sounds. This project's name comes from the Sumerians, who for the first time in history divided day and night into 12 hours. According to their beliefs, Sin is the moon god and Utu is the sun god.
