The absolute consideration of the acoustic environment within architectural design praxis has traditionally been reserved only for those specialised listening facilities such as concert halls or recording studios. This is in spite of numerous recent calls from architects and theorists such as Juhani Pallasmaa, Ted Sheriden, Karen Van Lengen, and Björn Hellström that architectural praxis must seek to move beyond what Jeremy Till describes as the vanity of form, and what Rafael Pizarro acknowledges as the seductive immediacy of pure visual articulations of space. That architectural design has traditionally been in a more than willing position to seek out myriad influences, theories, and extra-architectural knowledge has even led Jean-Claude Guédon and Botond Bognar to argue that architecture has ceased to occupy a finite domain – its boundaries have dissipated as the definition of what architecture is continues to evolve and expand.
