An acoustic device includes a member which divides an ear canal of a user and an external space when being attached to an ear or the ear canal of the user, a memory that stores instructions, and a processor that executes the instructions. The instructions cause the processor to perform, acquiring a sound signal indicating a sound, applying a filter processing to the acquired sound signal, the filter processing being changed in accordance with a predetermined condition, and radiating the sound indicated by the sound signal applied with the filter processing to the ear canal.
