This invention provides a light weight acoustic covering member having excellent characteristics in sound absorption and forming, and an acoustic member using such an acoustic covering member. An acoustic covering member 6 is formed by overlapping a stretchable paper sheet, which is creped and/or embossed, on one or two surfaces of a fibrous sheet. The stretchable paper sheet has a rate of crepe of 10 to 50%, a number projections of 20 to 200 pcs/cm<SP>2</SP>, the projections having a height of 0. 02 to 2. 00 mm. An acoustic member 8 is formed by overlapping a sheet shaped, gas permeable, porous material 7 on the acoustic covering member 6. |
