Abstract:
Both the medical and building authority requirements not to exceed a night-time indoor sound pressure level of 30 dB(A) in bedrooms and to ensure a sufficient hygienic minimum air exchange repeatedly pose major challenges for building professionals. The newly developed "attached soundproof window" can be a solution for this. The "attached soundproof window" ensures both sufficient air exchange, with low heat losses thanks to heat recovery, as well as very good sound insulation of up to 20 dB sound level difference in the case of a fully open window. The advantages of an "attached soundproof window" also include excellent summer thermal insulation, thermal bridge-free installation on the façade and all without reducing sound insulation. This article presents the operating principle of the "attached soundproof window" and shows which applications can be derived from it. In this article, the acoustic improvements that can be achieved are discussed based on measurement results.
