Double-mode Gauss-like time relaxation frequency spectrum $H\left(v\right)$ (71) (solid red line) and the corresponding models ${\overline{H}}_K\left(v\right)$ (42) for $K$ measurements of the relaxation modulus corrupted by additive independent noises uniformly distributed over the interval $\left[-0.005, 0.005\right] \mathrm{P}\mathrm{a}$: (a) $K=50, 100, 150$; (b) $K=150, 200, 300$.
