Schallisolierung einer Mehrzweckhalle - Inselregierung Gran Canaria

PRÄSENTATION
Große GelĂ€nde mit mehreren Hallen weisen in der Regel zahlreiche akustische Defekte auf, die mithilfe von schallabsorbierenden Materialien korrigiert werden mĂŒssen, mit denen man adĂ€quate RĂŒckstrahlungswerte erzielen kann, sodass in den RĂ€umen zeitgleich unterschiedliche AktivitĂ€ten durchgefĂŒhrt werden können. Dabei muss berĂŒcksichtigt werden, dass die Effekte der lĂ€ngeren RĂŒckstrahlungszeit durch das Nichtvorhandensein von schallabsorbierenden FlĂ€chen auf Böden, Decken und WĂ€nden die erforderlichen Parameter fĂŒr eine mĂŒndliche Kommunikation zwischen Sprechern und Zuhörern deutlich vermindern. Der Verlust der VerstĂ€ndlichkeit des gesprochenen Wortes in einer Umgebung mit stark erhöhter RĂŒckstrahlungszeit ist betrĂ€chtlich.

AcĂșstica Integral verfĂŒgt ĂŒber geeignete schallisolierende Materialien fĂŒr die entsprechende Anpassung der Akustik. Durch ihr dekoratives Aussehen und die Vielseitigkeit in Bezug auf GrĂ¶ĂŸe und Form lassen sich diese Materialien an jedes Design anpassen und korrigieren Probleme aufgrund fehlender Schallabsorption.

Nach einer grĂŒndlichen Analyse basierend auf LĂ€rmmessungen vor Ort konnten wir die RĂŒckstrahlungszeit in der Einrichtung erfassen und die störenden FrequenzbĂ€nder bestimmen, die dadurch entstehen, dass die Reflexionen auf wenig absorbierenden FlĂ€chen GerĂ€usche nicht abschwĂ€chen.Nachdem die Ziele bezĂŒglich der Akustik und die zu korrigierenden FrequenzbĂ€nder bestimmt waren, wurden die verschiedenen Materialien ausgewĂ€hlt, mit denen eine adĂ€quate Kontrolle der RĂŒckstrahlungszeit erreicht werden sollte.

Unser Fall betrifft ein großes GelĂ€nde der Inselregierung von Gran Canaria, das als Mehrzweckhalle (Konferenzraum, Ausstellungssaal, Messen etc.) dient. In der ersten Analyse erreichte die RĂŒckstrahlungszeit Werte um 5,5 Sekunden – völlig ungeeignet fĂŒr die Art der AktivitĂ€ten, die in dem GebĂ€ude durchgefĂŒhrt werden sollen.
Um mögliche Problemlösungen zu finden, wurde ein 3D-Modell des GelĂ€ndes mit den ursprĂŒnglichen Eigenschaften ohne SchalldĂ€mmung erstellt; es wurden verschiedene Optionen geprĂŒft und entschieden, dass die akustische Konditionierung mithilfe der Installierung von schallisolierenden Inseln erfolgen sollte, in unserem Fall 90 Einheiten Acustiart  fĂŒr die Decke, Farbe Titanium, 100 x 500 x 50 mm und 33 Einheiten Acustiart. Farbe Cherrry, 1500 x 1000 x 50 mm.
Mit dieser Installation konnte die RĂŒckstrahlungskurve auf einen Wert von 1,4 Sekunden verringert werden. Diese Reduzierung ist deutlich bemerkbar und passt sich adĂ€quat an alle Typen von AktivitĂ€ten an, die im GebĂ€ude durchgefĂŒhrt werden sollen. Der Kunde ist hoch zufrieden mit dem Ergebnis.
