transmission loss calculation

[rotia]

Hi, I´m sttarting with the software LMS Virtual Lab an d I need to calculate the transmission loss of a simple panel. My problem is that I can not find any tutorial about this kind of analysis.

So please, if you know something about this answer and let me know,

thank you.

Be careful to understand exactly what the desired result is and how your measurements contribute to its calculation. Don't just press a button marked "Transmission Loss" and assume that your combination of test equipment and sensor measurements will let the canned computation (usually based on pressure measurements) provide a sensible answer.
