A noise attenuating assembly for use in conjuction with an air conditioning unit having a sloped discharge opening is disclosed. The assembly includes a front wall and a pair of side walls forming a flow path for the conditioned air which is discharged to the space containing the unit. The assembly has a layer of sound attenuating material attached to the inside surface of the walls so that the assembly deflects and absorbs line-of-sight sound produced by the unit fan, thus reducing the noise level of the unit.
