Well, I’m a former (amateur) musician and I still find decibels perfectly appropriate—remembering that 10^0.3 ≈ 2 automatically gives you 10^0.6 ≈ 4, 10^0.9 ≈ 8, 10^1.2 ≈ 16 i.e. 10^0.2 ≈ 1.6, 10^0.5 ≈ 3.2 and going the other way 10^-0.3 ≈ 0.5 i.e. 10^0.7 ≈ 5, 10^0.4 ≈ 2.5 and so on. If those aren’t precise enough, sqrt(10) ≈ 3.16 also gives you 10^0.2 ≈ 1.58 and 10^0.8 ≈ 6.32.
