The elliptic and triangular flow coefficients ($\mathrm{v_n, \, n=2,3}$)measured in Pb+Pb ($\sqrt{s_{_{\rm NN}}} = 2.76$ TeV) and p+Pb ($\sqrt{s_{_{\rmNN}}} = 5.02$ TeV) collisions, are studied as a function of initial-stateeccentricity ($\varepsilon_n$), and dimensionless size characterized by thecube root of the mid-rapidity charged hadron multiplicity density$\mathrm{\left< N_{ch} \right>^{1/3}}$. The results indicate that the influenceof eccentricity ($\mathrm{v_n} \propto \varepsilon_n$) observed for large$\mathrm{\left< N_{ch} \right>}$, is superseded by the effects of viscousattenuation for small $\mathrm{\left< N_{ch} \right>}$, irrespective of thecolliding species. Strikingly similar acoustic scaling patterns of exponentialviscous modulation, with a damping rate proportional to $\mathrm{n^2}$ andinversely proportional to the dimensionless size, are observed for theeccentricity-scaled coefficients for the two sets of colliding species. Theresulting scaling parameters suggest that, contrary to current predilections,the patterns of viscous attenuation, as well as the specific shear viscosity$\left<\frac{\eta}{s}(\text{T})\right>$ for the matter created in p+Pb andPb+Pb collisions, are comparable.
