i have processed the .wav file and plotted the db(a) vs freqyncy data. But the RMS value using the in-built function of matlab returns a different value compared to Siemens Test center that i used to proess the audio file.
i Believe there is a difference between the rms formulas used in both the cases.
can anybody help me ?

It might just be a matter of scaling. For example, if there is a microphone involved, you may need to calibrate for that if the other software is.
