Abstract
A method of determining a set of individual HRTFs for a specific human includes: obtaining a set of approximate HRTFs; obtaining at least one measured HRTF of the specific human; determining a deviation of one of the at least one measured HRTF with relation to a corresponding one of the set of approximate HRTFs; and forming the set of individual HRTFs by modification of the set of approximate HRTFs based at least in part on the determined deviation.
Claims13
A method of determining a set of individual head-related transfer-functions (HRTFs) for a specific human, comprising:
- obtaining a set of approximate HRTFs;
- obtaining at least one measured HRTF of the specific human;
- determining a parameter based on one of the at least one measured HRTF, and a corresponding approximate HRTF from the set of approximate HRTFs, wherein the act of determining the parameter comprises determining a synthesizing filter or an impulse response;
- and
- forming the set of individual HRTFs for the specific human by modification of the set of approximate HRTFs based at least in part on the determined parameter;
- wherein the at least on measured HRTF is provisioned based on microphone signals from microphones.

A fitting instrument for fitting a hearing aid to a user, comprising:
- an input configured to receive a set of approximate head-related-transfer-functions (HRTFs) stored in a memory device;
- and a processor configured for
- obtaining at least one measured HRTF of the user;
- determining a parameter based on one of the at least one measured HRTF, and a corresponding approximate HRTF from the set of approximate HRTFs wherein the parameter comprises a synthesizing filter or an impulse response;
- and
- forming a set of individual HRTFs for the user by modification of the set of approximate HRTFs based at least in part on the determined parameter;
- wherein the processor comprises an input for obtaining the at least one measured HRTF, the at least one measured HRTF being provisioned based on microphone signals from microphones.
