Science Buddies: "Ask an Expert"

Hello,

I have a problem: how can I convert decibels into linear values? What is the linear unit for sound level measurement? How can I conver tlinear value back to decibels?

I am sorry for a lot of questions...

Thank you!

Alex,

This link gives you the background to understand the conversion:

You will need a calculator that performs log functions. If you don't have a physical calculator with these functions, you may have a virtual calculator in your computer that may be switched to the "scientific calculator mode".

Good Luck!
