Silent Emergency Call

In the journal Current Biology and Journal of Avian Biology, a journal of modern biology, papers were published on the effects of traffic noise on the cries of Black-capped Chickadee in North America. According to the paper, Black-capped Chickadees in cities increase frequency or volume to efficiently communicate to colleagues, avoiding their cries to not be buried in traffic noise. It is a painful strategy to survive in a rapidly changing environment. This is not just a matter for the North American chickadees. Similar results can be easily found in studies of birds living in the city center, such as the Eurasian Blackbird, which is easily found throughout Europe, and the Great tit (Parus major, Parus minor) that lives in Europe and East Asia. Wild animals, which have evolved to accommodate the noise they hear in their natural environment, are responding to the rapidly changing artificial noise environment. Sooyeun wants to reconstruct the phenomenon that birds are affected by traffic noise and reinterpret it from her own perspective using the properties of the virtual boundary that sound has. The title of the work, Silent Emergency Call, describes that a bird continues to send warning signals to colleagues in traffic noise, but it is too weak compared to traffic noise to be heard by colleagues. Silent Emergency Call is a sound installation using multiple channel speakers. The audience can enjoy the sounds from various directions in a spatial way.
