PROBLEM TO BE SOLVED: To reproduce a binaural signal subjected to personal adaptation by simply measuring the depth of the pinna of the ear of a user.SOLUTION: A three-dimensional sound reproduction device (10) includes a processor (12), and a right and left head transfer function set is previously registered for each average value of the depth (d1) of a first part of the pinna of a user in a head transfer function database (22). When the depth of a first part of the ear of a user measured actually is inputted from an input device (20), the depth of the ear is considered as an average value, and a set of head transfer function registered for the average value is read as the head transfer function subjected to personal adaption of the user, and the right and left binaural signals are generated by performing convolution operation of a sound source signal from a sound source (14), and then reproduced by a headphone (18). |
