Abstract
A sound output device includes an acquisition unit, an ear speaker, and a sound controller. The acquisition unit acquires data of an information sound providing an operator with information. The ear speaker outputs the information sound such that sound pressure of the information sound at a position of an ear of the operator is higher than sound pressure at positions other than the position of the ear. The sound controller controls the ear speaker to emphasize the information sound more when the information sound indicates a high degree of necessity for the operator to take action against the information sound than when the information sound indicates a low degree of the necessity.
