Motivated by the recent discoveries of binary black-hole mergers by theAdvanced Laser Interferometer Gravitational-wave Observatory (Advanced LIGO),we investigate the prospects of ground-based detectors to perform aspectroscopic analysis of signals emitted during the ringdown of the final Kerrblack-hole formed by a stellar mass binary black-hole merger. If we assume anoptimistic rate of 240 Gpc$^{-3}$yr$^{-1}$, about 3 events per year can bemeasured by Advanced LIGO. Further, upgrades to the existing LIGO detectorswill increase the odds of measuring multiple ringdown modes significantly. Newground-based facilities such as Einstein Telescope or Cosmic Explorer couldmeasure multiple ringdown modes in about thousand events per year. We performMonte-Carlo injections of $10^{6}$ binary black-hole mergers in a search volumedefined by a sphere of radius 1500 Mpc centered at the detector, for variousproposed ground-based detector models. We assume a uniform random distributionin component masses of the progenitor binaries, sky positions and orientationsto investigate the fraction of the population that satisfy our criteria fordetectability and resolvability of multiple ringdown modes. We investigate thedetectability and resolvability of the sub-dominant modes $l=m=3$, $l=m=4$ and$l=2, m=1$. Our results indicate that the modes with $l=m=3$ and $l=2, m=1$ arethe most promising candidates for sub-dominant mode measurability. We find thatfor stellar mass black-hole mergers, resolvability is not a limiting criteriafor these modes. We emphasize that the measurability of the $l=2, m=1$ mode isnot impeded by the resolvability criterion.
