By changing the headphones of the self-independent nature of personalized sound into a new medium of communication, Byungjun Kwon presents and experiments with harmonious connection between community members. Visitors wear headphones equipped with sound of nature and composition from its motifs, walk through the exhibition space, and sense and hear what the other party is hearing when approaching other visitors. In addition to your own sounds, you can mix your opponent's sounds over a physical distance, and then you can exchange your own sounds with the other's sounds by bowing to each other. It presents a new model of a society where sounds are used to reach out to others, create a bridge, and share things with each other.
