PROBLEM TO BE SOLVED: To provide a head transfer function selection apparatus capable of facilitating selection of a head transfer function approximate to an own head transfer function.SOLUTION: A measurement part 41 acquires a head impulse response, on the basis of a voice signal collected by a microphone 20 fitted into a user's ear, with a predetermined voice as a measurement signal generated from a speaker 6. A feature amount extraction part 42 extracts a feature amount of a frequency characteristic corresponding to the head impulse response. A characteristic selection part 43 selects any head transfer function from a database 301 linking a head transfer function of each of a plurality of persons to a feature amount of the head transfer function, on the basis of the extracted feature amount.SELECTED DRAWING: Figure 1 |
