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
