A project of Audiochmura (Audiocloud) was inspired by the concept of Audioarchitektura (Sonicarchitecture) - brainchild of artist Piotr Adamski (adamski / brzuzan) and mode:lina. It is a sonic installation using corrugated pipes as amplifiers emitting sounds gathered around its actual position. The shape of a cloud relates to something ephemeral, almost non-existent and likely to move. Audioarchitektura (Sonicarchitecture) is a utopian vision of a city that cannot be heard. An innovative system of sound emission, which isolates people from the unbearable audiosphere of crowded streets, traffic and all the noise that unnaturally has become an inseparable part of our life. Invisible Sonic-buildings, spread along the sidewalks, in parks and boulevards, emitting sound waves that drown out the city noise. Passer-by walking in their range are surrounded by the sound of hypnotic composition of Steve Reich’s concert, broadcasted live from the concert hall or a melody of raindrops falling on the tin roofs of urban buildings. Today this is a utopian technology, but Sonic Architecture is also a basis for discussion on acoustic ecology, city’s acoustic landscape and its impact on the inhabitants.
