Eine Anwendung der derzeit normativ abgedeckten Verfahren f\u00fcr diese Baukonstruktionen ist ausdr\u00fccklich in den betreffenden Regelwerken ausgeschlossen. Die derzeit auf wissenschaftlicher Basis stehenden Berechnungsverfahren bieten im betrachteten Frequenzbereich zwischen 50\u00a0Hz und 5000\u00a0Hz keine ausreichende Zuverl\u00e4ssigkeit der Prognosequalit\u00e4t in den schalltechnischen Kenngr\u00f6\u00dfen zur Beschreibung des bauakustischen Verhaltens solcher Konstruktionen. Neben den zu erwarteten diffusen Berechnungsergebnissen im unteren Frequenzspektrum ist eine Abbildung der Verbindungsausbildung zwischen Plattenwerkstoff und Tragkonstruktion, die in dem betreffenden Frequenzbereich einen wesentlichen Einfluss aufweisen, nicht m\u00f6glich. Ebenso ist es daher auch nicht m\u00f6glich, mittels bestehender Verfahren die Auswirkungen von schwankender Verarbeitungsqualit\u00e4t, wie z.\u00a0B. den Schraubenanzugsmoment, in die Prognose der Kenngr\u00f6\u00dfen einflie\u00dfen zu lassen. Das entwickelte Simulationsmodell in der Finite Elemente-Umgebung \u201eCOMSOL 5.6\u201c bietet die M\u00f6glichkeit der Ber\u00fccksichtigung der Parameter Schraubendimensionen, Schraubenabstand, Anzugsmoment und Position der Schrauben auf der Tragkonstruktion. Durch die numerischen Ergebnisse des Prognosemodells k\u00f6nnen somit die Wechselwirkungen zwischen den unterschiedlichen Wandkomponenten und deren Verbindungselementen untersucht und optimiert werden.<\/jats:p>","DOI":"10.1007\/s00502-021-00877-2","type":"journal-article","created":{"date-parts":[[2021,3,25]],"date-time":"2021-03-25T08:05:05Z","timestamp":1616659505000},"page":"179-189","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Modifikation eines Modells von Verbindungsmitteln zur Prognose des Schalld\u00e4mmma\u00dfes von Leichtbaukonstruktionen mittels Finite Elemente-Methode im erweiterten Frequenzbereich","Modification of a model of connection parts in the finite element method for the prediction of the sound transmission loss of lightweight constructions in the extended frequency range"],"prefix":"10.1007","volume":"138","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3714-7108","authenticated-orcid":false,"given":"Maximilian","family":"Neusser","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1142-5517","authenticated-orcid":false,"given":"Thomas","family":"Bednar","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2021,3,25]]},"reference":[{"key":"877_CR1","volume-title":"Results from the search for available systematic reviews and meta-analyses on environmental noise","author":"M.
