Converting sound pressure levels (dB) to psd (g^2/Hz)
Converting sound pressure levels (dB) to psd (g^2/Hz)
(OP)
I have data supplied as broadband sound pressure levels in dB against frequency. I need to convert this into a psd (g^2/Hz) versus frequency. Anyone know how to do this?

These methods are for structures such as plates and cylinders.
The Franken method is used for cylinders.
In addition, Steinberg gives a simplified example in text.
This type of analysis is called "vibroacoustics."

Lo and behold, all the low-frequency floor vibration modes were equally well-represented by the acoustic data.
