Hello,

I've been reading about attenuation, and I wonder if there's a way to determine the distance to your source. Forgive my poor writing; I'm new to the topic.

I understand that equation for linear attenuation is

where:

My question is this: if I have the information

For a simple-minded example, would it be possible to take measurements of intensity at a variety of perpendicular distances in order to determine the geometric spreading and work backward from that to find distance

Thank you kindly for your time and knowledge.

I understand that equation for linear attenuation is

*I = I*

_{0}e^{-μx}**I**= intensity

**I**

_{0}= initial intensity

**μ**= attenuation coefficient

**x**= distance traveled through medium

My question is this: if I have the information

**μ**and**I**, is there some way to determine**x**, and/or**I**? It seems that I need to find either of those to find them both, so I wonder if there's some other measurements I could take that would make this possible._{0}For a simple-minded example, would it be possible to take measurements of intensity at a variety of perpendicular distances in order to determine the geometric spreading and work backward from that to find distance
