Realisation of the unit Watt in airborne sound
, 2020 Die zentrale Größe akustischer Normgebung ist die von einer Quelle abgestrahlte Schallleistung. Ausgehend vom derzeitigen Stand der Wissenschaft in der Schallleistungsmessung wird diese Arbeit aufzeigen, dass die Erstellung einer metrologisch gültigen Kalibrierkette für diese Größe realistisch ist.

Primary Sound Power Sources for the realisation of the unit watt in Airborne sound
, 2016 At present, airborne sound power is not a directly measurable quantity. It is calculated from sound pressure measurements performed in special environments, e.g. free or diffuse fields or from sound intensity measurements using 2-microphone probes. All the different methods are lacking traceability and transparent uncertainty budgets.
