Das Dokument beschreibt ein verhältnismäßig einfaches Verfahren der Genauigkeitsklasse 2 zur Bestimmung der Schallleistungspegel kleiner, transportabler Geräuschquellen. Für die Messungen wird die Quelle in einem Sonder-Hallraum aufgestellt. Leitlinien für die Ausführung von Sonder-Hallräumen sind in einem Anhang aufgeführt. Der A-bewertete Schallleistungspegel der Quelle wird bei dem beschriebenen Direktverfahren aus der Messung der A-bewerteten Schalldruckpegel bestimmt; es wird keine Vergleichsschallquelle benötigt. In Ergänzung wird auch noch ein Vergleichsverfahren beschrieben.
