  We present here a detailed study of the quasi-normal spectrum of
brane-localised Standard Model fields in the vicinity of D-dimensional
black-holes. A variety of such backgrounds (Schwarzschild, Reissner-Nordstrom
and Schwarzszchild-(Anti) de Sitter) are investigated. The dependence of the
quasi-normal spectra on the dimensionality D, spin of the field s, and
multipole number l is analyzed. Analytical formulae are obtained for a number
of limiting cases: in the limit of large multipole number for Schwarzschild,
Schwarzschild-de Sitter and Reissner-Nordstrom black holes, in the extremal
limit of the Schwarzschild-de Sitter black hole, and in the limit of small
horizon radius in the case of Schwarzschild-Anti de Sitter black holes. We show
that an increase in the number of hidden, extra dimensions results in the
faster damping of all fields living on the brane, and that the localization of
fields on a brane affects the QN spectrum in a number of additional ways, both
direct and indirect.
