A sheet separating device having a noise suppressing function is used with an auto document feeder. The sheet separating device includes a sheet separating pad, a sheet separating holder, a resilient element and a noise suppressing element. The sheet separating pad cooperates with a sheet separating roller to separate a paper sheet fed into a sheet-guiding path of the auto document feeder. The sheet separating pad is disposed on the sheet separating holder. The resilient element is sustained against or coupled to the sheet separating holder, so that sheet separating pad disposed on the sheet separating holder is urged against the sheet separating roller. The noise suppressing element is arranged on the sheet separating holder for altering the natural frequency dynamic response of an assembly of the sheet separating pad and the sheet separating holder, thereby shifting the natural frequency dynamic response of the assembly of the sheet separating pad and the sheet separating holder from the working frequency and the harmonic frequency of the sheet separating roller.
