Claim 0:
1. An out-of-head localization filter determination system, comprising:
an output unit configured to be worn on a user and output sounds to an ear of the user;
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;
a measurement processor configured to output a measurement signal to the output unit and acquire a sound pickup signal output from the microphone unit, and thereby measure ear canal transfer characteristics; and
a server device configured to be able to communicate with the measurement processor, wherein
the measurement processor:
measures first car canal transfer characteristics from a first position to the microphone with a driver of the output unit being at the first position;
measures a second ear canal transfer characteristics from a second position, different from the first position, to the microphone; and
transmits user data related to the first and second ear canal transfer characteristics to the server device, and

the server device includes:
a data storage unit configured to store first preset data related to spatial acoustic transfer characteristics from a sound source to an ear of a person being measured and second preset data related to ear canal transfer characteristics of the ear of the person being measured in association with each other, and store a plurality of the first and second preset data acquired for a plurality of persons being measured;
a comparison unit configured to compare the user data with the plurality of second preset data; and
an extraction unit configured to extract first preset data from the plurality of first preset data based on a comparison result in the comparison unit.
