What do b and n signify in the damped harmonic motion equation?

[romd]

Homework Statement

Concerning damped harmonic motion (mass on a spring using cardboard discs as dampers); for the equation (below) of the graph describing the effect of different sized dampers on the time taken for amplitude of oscillations to halve, what do b (y-intercept) and n (gradient) represent? (A=area of damper; T=time taken for amplitude to halve)

Homework Equations

$$T=b.A^n$$
(i.e. $$ln(T)=n.ln(A) + ln(b)$$ )

The Attempt at a Solution b represents the time taken for the amplitude to halve when the area of the damper is equal to 1. n represents the rate at which the time taken for the amplitude to halve decreases as the area of the damper increases.
