Eleven-year-old SUZUKI Ryota became inter- ested in electromagnetic waves and repeated experiments for the experience of it. His inter- est was expanded to high-frequency waves, which become more dif cult to hear as people age. This acoustic work includes the process- es he employed to create a sampling of high frequencies using an iPad and what he discov- ered and felt. This summary video work puts together behind-the-scenes lm of viewpoints and realizations.
