## Homework Statement

Harry and Sally are sitting on opposite sides of a circus tent when and elephant trumpets a loud blast. If Harry experiences a sound intensity level of 65dB and Sally only 55dB, what is the ratio of the distance between Sally and the elephant to the distance between the elephant and Harry?

## Homework Equations

I=P/(4piR^2)

B=10log(I/10^-12)

## The Attempt at a Solution

65=10log(I/10^-12)

so I(harry)=10^-5.5

55=10log(I/10^-12)

so I(sally)=10^-6.5

*I have no idea where to go from here or if that was even the correct first step to take.

If I knew the Power(P), I would be able to find the radius and get distance from that, but I don't have a way to calculate that.
