## Homework Statement

If I measure a sound

**intensity**of 1.0 at distance

*R*from its source, what intensity would I measure at distance

*3R*in a free, unbounded space? What is the difference in decibels?

## Homework Equations

I know that the equation for this is 10 (log R2/R1)

## The Attempt at a Solution

I thought that the answer could be a 9.54 dB difference. I did: 10(log(9) to figure this out but the answer doesn't seem correct. Any help with answering this question would be greatly appreciated. Thank you
