             Abstract
 
A compact Riemannian manifold  (M,g)  is said to be locally audible if the
following statement holds for every metric  g'  on  M  which is
sufficiently close to  g:  if the metrics  g  and  g'  are isospectral
then they are isometric.
 
   We prove local audibility of a compact locally symmetric Riemannian manifold
of negative sectional curvature.
Along with the proof, I will try to give you some flavor of spectral geometry.
