Attenuation and source positioning

[QUOTE="Dade Murphy, post: 5461364, member: 592705"] 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 [INDENT][INDENT][I]I = I[SUB]0[/SUB]e[SUP]-μx[/SUP][/I][/INDENT][/INDENT] where: [INDENT][B]I[/B] = intensity [B]I[/B][SUB][B]0[/B][/SUB] = initial intensity [B]μ[/B] = attenuation coefficient [B]x[/B] = distance traveled through medium[/INDENT] My question is this: if I have the information [B]μ[/B] and [B]I[/B], is there some way to determine [B]x[/B], and/or [B]I[SUB]0[/SUB][/B]? 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. 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 [B]x[/B]? Thank you kindly for your time and knowledge. [/QUOTE]
