The present invention provides a multilayer dash isolation pad having superior formability and sound absorption performance. The multilayer dash isolation pad includes a decoupler and a sound absorption and insulation layer. The decoupler is a soft felt manufactured from urethane foam or octalobal cross-section fiber, and the sound absorption and insulation layer includes a compressed felt manufactured from octalobal cross-section fibers. In particular, the shape factor (±) of the octalobal cross-section fiber is 2.0 to 2.7. Particularly, the multilayer dash isolation pad according to the present invention does not decrease thickness or be contracted upon press molding after preheating felt, such that superior formability in components can be obtained and a sound absorption coefficient may be enhanced without increase in the weights and thicknesses of the decoupler and the sound absorption and insulation layer.
