Click to learn more about the Aerosonar project.
Aerosonar is a spatial audio installation which displays air pollution on a macro level in the micro environment of the exhibition space, at the same time emphasising a human impact on air pollution. The musical composition of the installation allows the air pollution to be experienced largely through the sense of hearing, which is otherwise not the case. Human impact on the installation itself and alternating spatial conditions result in changes in the musical composition, which make visitors aware of their impact.
Musical composition is created through the sonification of downtown Belgrade air pollution data, having each selected air pollution parameter correspond to a sound. Visitors’ impact is recorded based on their behaviour in the space of the installation. Each impact is recorded by the movement sensors, and this impact is then translated into a function which modifies the original air pollution com- position. Visitors experience the installation space through a mutual relationship of the air pollution parameters, as well as through their personal relation to the same parameters.
