G^2/hz asd
WebMar 29, 2005 · GREGLOCOCK: Not sound pressure levels but an acceleration time history. The one third octave analysis is done on the acceleration time history. The PSD is done on the acceleration time history also. The time history has to be in G peak since when the PSD is performed it convets it to Grms^2/hz.

In this test type, such term as ASD (acceleration spectral density) is often used. This term should be interpreted as “random vibration acceleration spectral density measured as “squared acceleration divided by frequency (g 2 /Hz)”. ASD spectrum determines ASD measurement method within …
