Classification: CPC H | IPC H

Claim 2:
3. An out-of-head localization filter determination method for determining an out-of-head localization filter for the user by using:
an output unit configured to be worn on a user and output sounds to an ear of the user; and
a microphone unit, including a microphone, configured to be worn on the ear of the user, the microphone picking up sounds output from the output unit, the out-of-head localization filter determination method comprising:
a step of measuring first ear canal transfer characteristics from a first position to the microphone and second ear canal transfer characteristics from a second position to the microphone;
a step of acquiring user data based on measurement data related to the first and second ear canal transfer characteristics;
a step of storing a plurality of first and second preset data acquired for a plurality of persons being measured, in such a way that associates the first preset data related to spatial acoustic transfer characteristics from a sound source to ears of persons being measured and the second preset data related to ear canal transfer characteristics of the cars of the persons being measured; and
a step of comparing the user data with the plurality of second preset data and thereby extracting first preset data from the plurality of first preset data.
