Default How to extract Sound pressure from wav file?

I have to extract the sound pressure [db (A)] over time to determine
the average over 5 seconds. This I must be able to automate in order
to apply it to about 2000 sound files.
The software DIAdem , LabVIEW and MatLab are available. Another
freeware would be no problem.
Does anyone have an idea for it?

You are asking us is like how to determine the depth of the ocean by looking
at the waves.



That can be done given sufficient [possibly infinite] other information.
