Figuring out changes in Intensity (Inverse Square Law)

[QUOTE="RichardGib, post: 4973359, member: 537623"] [h2]Homework Statement [/h2] If I measure a sound [B]intensity[/B] of 1.0 at distance [I]R[/I] from its source, what intensity would I measure at distance [I]3R [/I]in a free, unbounded space? What is the difference in decibels? [h2]Homework Equations[/h2] I know that the equation for this is 10 (log R2/R1) [h2]The Attempt at a Solution[/h2] 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 [/QUOTE]
