PROBLEM TO BE SOLVED: To generate a notification sound which is outputted at a desired position in stable localization.SOLUTION: A dummy head device 200 includes a dummy head 210 and a microphone 220. An audio output unit 100 includes a speaker 150 outputting a measurement signal. A notification sound generator 300 includes a sound field measurement control unit 311 for measuring the transfer function from the speaker 150 to the microphone 220, a crosstalk cancellation filter generation control unit 312 generating a crosstalk cancellation filter for cancelling crosstalk at a position where the microphone 220 is attached on the basis of the transfer function, a crosstalk cancellation verification unit 313 for extracting a frequency band of high crosstalk cancellation effect in the crosstalk cancellation filter, and a notification sound generation control unit 314 for generating a notification sound on the basis of the frequency band thus extracted. |
