We derive a fast decay estimate for the wave equation with a local degenerate dissipation of the type a(x)u t in a bounded domain โ„ฆ. The dissipative coefficient a(x) is a nonnegative function only on a neighborhood of some part of the boundary โˆ‚โ„ฆ and may vanish somewhere in โ„ฆ. The results obtained e
