Does the Dutta-Horn fluctuator model describe 1/f noise in metal films?

In the Dutta-Horn model $S(f, T)$ is a superposition of Lorentzians from thermally activated fluctuators with rates $\left(1/\tau_0\right) \exp(-E/T)$ and a smooth activation-energy distribution $D(E)$; it predicts $\alpha(f, T) = 1 - (d \ln S/d \ln T - 1)/\ln(2 \pi f \tau_0)$, where $\alpha = -d \ln S/d \ln f$. For thin metal films (for example Au, Cu, Ag, Bi) over $f \sim 10^{-3} \text{ to } 10^{3}\,\mathrm{Hz}$ and $T \sim 10 \text{ to } 500\,\mathrm{K}$, determine whether this relation holds with a single $\tau_0$, and whether $D(E)$ inferred from the noise matches $D(E)$ obtained independently (from internal friction or defect spectroscopy).

Noise spectra over at least six decades of $f$ at many temperatures on one film, with the fluctuator energy distribution measured independently, testing the predicted relation with $\tau_0$ as the only parameter.
