I'm working on a fantasy siren map and trying to figure out how far Modulator 1004's, 2008's and 3012's can be heard at about 60db, or clearly. Can anybody help me with this?

Subtract -10 (db) from distance doubled.
1004: 108db-10(5)=58db. Double distance of 100feet by five
2008: 112db-10(5)=62db. Double distance of 100feet by five
3012: 116db-10(5)=66db. Double distance of 100feet by five
1004: approximately 2,900 feet
2008: approximately 3,400 feet
3012: approximately: approximately 3,900 feet
Equation:
r=10(x)=60 then 100(2^x)
