Kurzfassung deutsch:
(no english version) Within an ongoing project, we explore the potential of double skin facades to provide
both noise control and natural ventilation capability. Three strategies are investigated: i)
Manipulation of sound paths via offset of the openings in the two shells of the façade; ii)
Application of absorbing materials in the interstitial space of the façade; iii) Active noise cancelling
methods utilizing wave-destructive interference. This contribution describes the overall project but
focuses primarily on the active noise cancellation approach. Aside from a comprehensive
background research on existing technology, we undertook the design of an actual setting for noise
cancellation testing with suitable low-cost components as a proof-of-concept. Results of the
experiments are expected to inform subsequent efforts to include noise-cancelling technology in
double skin facades.
