An acoustical panel is formed from a core of glass fiber reinforced material which is acoustically porous so as to absorb sound waves with the core being sufficiently rigid to form the panel for supporting within an area where sound waves are to be absorbed. On the front surface is adhesively attached a sheet of wood veneer to provide an attractive front surface for presentation into the area such that the sound waves in the area impact upon the sheet. The sheet is perforated prior to adhesive attachment over its entire surface with an array of punched holes of a number and size sufficient to allow passage through the sheet of sound waves for transfer into the core so that the punched holes extend through the sheet only.
