Schallquellen

Für bauakustische Messungen sind Schallquellen erforderlich, die entsprechenden Normen, wie z. B. ISO140, erfüllen.
Die Schallquellen von Brüel & Kjaer sind für den Bereich Bauakustik optimiert und garantieren eine omnidirektionale Abstrahlung zur Anregung von Räumen, Wänden, Fassaden und Fenstern. Für Trittschallmessung wird ein Normhammerwerk angeboten.
