math calculation problem when looking for silence

Tech-Archive recommends: Speed Up your PC by fixing your registry

Hi,
I have basic math calculation understanding problem.
Let say user selectable Silence level is 5dB.
My code is calculating average volume value carrying by the receiving
buffer.
That value is just an absolute value (in range of 0 to 70)
How should I relate that average value to that Silence level threshold set
at 5 dB to find out if that qualifies as a silence or not?
What kind of calculation that does it take?
Your help with the formula will be deeply appreciated,
Jack
