Optimierung des Trittschallschutzes von Holzbalkendecken in Gründerzeithäusern – Teil 1: Problemstellung und Sanierungsmöglichkeiten.

Impact sound insulation in renovated Wilhelminian‐style buildings – Part 1: Problem statement and renovation options Gassner & Partner Baumanagement GmbH, in collaboration with TU Wien, conducted a study to optimize impact sound insulation in Wilhelminian‐style building renovations. Historical renovations lacked specific sound standards, causing resident disruption. The research varied parameters like screed thickness, impact sound insulation, aggregate, and suspended subceilings to assess impact sound protection per ÖNORM B 8115‐5. Initial analysis of three properties showed reasonable protection in existing wooden beam ceilings. Suspended subceilings significantly improved sound levels, with the spectrum adaptation value CI,50‐2500 crucial for higher classification. Measurements during multiple renovations demonstrated that these measures are reproducible and can exceed new construction standards, significantly enhancing living comfort in historic buildings.
