Experiments on turbocharger compressor acoustics

Abstract

Hundreds of noises wove themselves into a wiry texture of sound with barbs protruding here and there, smart edges running along it and subsiding again, with clear notes splintering off and dissipating. By this noise alone, whose special quality cannot be captured in words, a man returning after years of absence would have been able to tell with his eyes shut that he was back in the Imperial Capital and Royal City of Vienna.
