Abstract/Summary

The Earth and atmosphere are in constant motion. Volcanoes, glaciers, earthquakes, thunderstorms, and even the aurora borealis produce powerful low-frequency sounds known as infrasound. Infrasound is constantly passing through our atmosphere at frequencies of less than 20 Hz, below the range of human hearing, which is effectively an inaudible symphony. Inspired by wanting to allow physical access to this natural phenomenon, a collaboration between the worlds of contemporary art and meteorology has been developed. This led to a project called hertz, named after the 19th century physicist Heinrich Hertz, whose surname provides the scientific unit (Hz) for frequency. Hertz explores the manifestation of the hidden vibrations of our own planet and the secret harmonies of our stars. The manifestation of the hidden vibrations of our own planet was principally achieved using a subwoofer and furniture adapted to vibrate to the amplitude of infrasonic waves from pre-recorded sources and in real time. The project's motivations are to explore new methods for experiencing and re-engaging with parts of our planet through this phenomenon. Hertz has had a UK national tour in which 7000 people interacted with the piece, of which approximately 85 % felt more reconnected to the environment after interacting with the installation. This paper describes the concepts, creative ideas, technology, and science behind the project. It addresses its development, including the steps to make it accessible for all, and examines its impact on those who created and interacted with the work.
