Abstract
An engine sound control device includes: a setter to set point information including coordinates indicating one of multiple cells of a driving state space represented by a coordinate system with parameters indicating a driving state as axes, and spectral information of a target engine sound at the cell; a setter to set region information indicating a driving scene region; a processor to perform an interpolation process to calculate spectral information of an engine sound for each of target cells of the multiple cells for which the point information is not set, based on the point information and region information, and generate a map including spectral information of an engine sound at each cell, from the point information and information obtained by the process; a processor to output a control parameter based on the map; and a controller to cause a unit to output a sound based on the control parameter.
