Singular values of the matrix \(\mathbf {W}_{\mathrm {t}}\hat {\mathbf {H}}_{\mathrm {t}}\) (\(L^{\mathrm {t}}_{g} = 1947\)) and of two sub-matrices \(\mathbf {W}_{\mathrm {s}}\hat {\mathbf {H}}_{\mathrm {s}} \big (L^{\mathrm {s}}_{g} = 1000\) and \(L^{\mathrm {s}}_{g} = 300\big)\) for PMINT. The largest and the smallest non-zero singular values of each matrix are explicitly marked. The considered acoustic system is system S1 described in Section 6.1
