Description: Das Projekt "Schallmessung von Spacelab ECLS Avionics Fan Assembly und Avionics Heat Exchanger Assembly ein einem Reverberier - Raum (Nachhall/Raum)" wird vom Umweltbundesamt gefördert und von Dornier SystemConsult GmbH durchgeführt. The objective of this test was to measure the sound emission from the Spacelab ECLS Avionics Fan Assembly coupled with the Spacelab ECLS Avionics Heat Exchanger Assembly. From the obtained third-octave sound pressure spectra measured in the reverberation room octave sound pressure and power spectra were calculated for the three main noise sources of the assemblies: casing noise, outlet noise, inlet noise.
