Abstract
An information processing apparatus includes: an estimator configured to estimate, based on biological information of a human subject, a sleep indicator indicative of a depth of sleep of the human subject; and a volume controller configured to control a volume adjuster that generates a second playback sound signal by adjusting an amplitude of a first playback sound signal, such that the first playback sound signal is adjusted based on the sleep indicator and a volume of an ambient sound in an environment in which the human subject is situated.
