A sound pressure level prediction apparatus includes a storage unit for storing measured sound pressure levels. The sound pressure level prediction apparatus also includes an acquisition unit configured to acquire sound pressure levels measured at a plurality of locations for a first fan and at least one sound pressure level for a second fan, and the at least one sound pressure level being measured at the same location as at least one of the plurality of locations used for measuring the sound pressure levels for the first fan. The sound pressure level prediction apparatus further includes a prediction unit configured to predict, based on the acquired sound pressure levels of the first fan and the at least one sound pressure level for the second fan, a sound pressure level for the second fan at a location where the sound pressure level for the second fan has not yet been measured.
