With the calculation of sound pressure level with the following eqn:
"'(βdB)=10*LOG((I(W/(m^2)))/(ⒸI0))' "
I was unable to obtain any sensible result. Reason: contrary to the HP50g, DB48X calculates LOG as LN and not as the usual convention of a logarithm in base 10. If we maintain this we have to explicitly write "LOG10" to be precise. BUT if we want to maintain some compatibility with HP50g, I think that LOG should design LOG10. By the way "LOG10" is not even a function in HP50g, it is interpreted as a variable name.
