## Abstract We study a decay property of solutions for the wave equation with a localized dissipation and a boundary dissipation in an exterior domain ฮฉ with the boundary โฮฉ = ฮ~0~ โช ฮ~1~, ฮ~0~ โฉ ฮ~1~ = โ ๏ธ. We impose the homogeneous Dirichlet condition on ฮ~0~ and a dissipative Neumann condition on
