抄録	Lattice vibrations on two-dimensional Penrose lattices are investigated numerically. The resultant spectra exhibit several peaks similar to those of disordered systems. From the dependence of the vibrational phase difference and the distribution of the local elastic energy on the different boundary conditions, it is found that the lattice vibrations of this system seem to be isotropic and localized above a certain critical frequency. The spectral peaks are attributed to van Hove singularities and localization.
