There are provided a paper conveying apparatus, a jam detection method and a computer-readable, non-transitory medium that can suppress erroneous detection of a jam. The paper conveying apparatus includes a sound signal generator, provided with a sound detector near a conveyance path of a paper, for generating a sound signal, and a sound jam detector for determining whether a jam has occurred based on a variation of a component of the sound signal.
