An engineering method to measure structure-borne sounds transmitted through the building partitions
In this paper, the authors present an engineering method to identify the transmission paths of structureborne sounds. The method is based on the use of a standardised impact sound source with an insulation case. The advantage of this approach is the possibility of obtaining repeatable results because the method allows the separation of structure-borne and airborne sounds; the latter do not interrupt the measurement even in the case of loose connections or elements of low acoustic insulation. The research on the verification of the method was performed on the façade of the Cracow Philharmonic building; the main structureborne sound transmission paths were determined successfully. Knowledge of the sound transmission paths allows the subsequent design of efficient vibroacoustic protection.

Metoda inżynierska pomiaru dźwięków materiałowych przenikających przez przegrody budowlane
Streszczenie
W artykule zaproponowano inżynierską metodę identyfikacji dróg transmisji dźwięków przenoszonych drogą materiałową przy użyciu wzorcowego źródła dźwięków uderzeniowych z odpowiednią obudową dźwiękoizolacyjną. Zaletą tego podejścia jest możliwość uzyskania powtarzalnych wyników dzięki odizolowaniu dźwięków uderzeniowych od powietrznych, które nie zakłócają pomiaru w razie występowania nieszczelności lub elementów o niskiej izolacyjności akustycznej. W celu weryfikacji metody przeprowadzono badania budynku Filharmonii Krakowskiej – wyznaczono główne drogi transmisji dźwięków przenoszonych drogą materiałową. Ich znajomość jest niezbędna do projektowania skutecznej ochrony dźwiękoizolacyjnej.
Słowa kluczowe: dźwięk uderzeniowy, drgania, promieniowanie dźwięku
