Query: Acoustic scaling of linear and mode-coupled anisotropic flow;
  implications for precision extraction of the specific shear viscosity   The $\mathrm{n^{th}}$-order linear flow coefficients $\mathrm{v^L_n \,
(n=2,3,4,5)}$, and the corresponding nonlinear mode-coupled ($\mathrm{mc}$)
coefficients $\mathrm{v^{mc}_{4,(2,2)}}$, $\mathrm{v^{mc}_{5,(2,3)}}$,
$\mathrm{v^{mc}_{6,(3,3)}}$ and $\mathrm{v^{mc}_{6,(2,2,2)}}$, are studied for
Pb+Pb collisions at $\sqrt{s_{_{\rm NN}}} = 2.76$ TeV. Both sets of
coefficients indicate a common acoustic scaling pattern of exponential viscous
modulation, with a rate proportional to the square of the harmonic numbers and
the mean transverse momenta (respectively), and inversely proportional to the
cube root of the charged particle multiplicity ($\mathrm{(N_{ch})^{1/3}}$),
that characterizes the dimensionless size of the systems produced in the
collisions. These patterns and their associated scaling parameters, provide new
stringent constraints for eccentricity independent estimates of the specific
shear viscosity ($\eta/s$) and the viscous correction to the thermal
distribution function for the matter produced in the collisions. They also give
crucial constraints for extraction of the initial-state eccentricity spectrum.
