PROBLEM TO BE SOLVED: To provide a sound reproduction device capable of automatically rewinding a reproduction position in accordance with a hearing loss period due to the increase of a noise level.SOLUTION: A sound reproduction device includes: sound content storage means for holding sound content; reproduction control means for reproducing the sound content; and noise detection means for detecting a noise level. The reproduction control means includes: noise increase position storage means for storing the reproduction position of the sound content when a noise level exceeds a first threshold as a noise increase position; hearing loss period measurement means for measuring a time between a time point when a noise level exceeds the first threshold and a time point when a noise level becomes lower than a second threshold as a hearing loss period; a rewinding time determination means for determining a rewinding time on the basis of the hearing loss period; and rewinding reproduction means for rewinding the reproduction of the sound content to a position wound back from the noise increase position by the rewinding time when the hearing loss period is terminated. |
