Abstract

A method for determining a set of individual HRTFs for a particular person comprising: obtaining a set of approximate HRTFs; obtaining at least one measured HRTF for the particular person; determining one of the at least one measured HRTF relative to the set of approximate HRTFs a bias for a corresponding one of the HRTFs; and forming the set of individual HRTFs by modifying the set of approximate HRTFs based at least in part on the determined bias.

Description

technical field [0001] A new method of determining an individual's HRTF, a new fitting system configured to determine an individual's HRTF according to the new method, and a hearing instrument, or a device for providing audio to the hearing instrument, are provided , where individual HRTFs were determined according to the new method. Background technique [0002] It has been reported that hearing aid users have a poorer ability to localize sound sources while wearing their hearing aids than without their hearing aids. For the hearing impaired population, this represents a serious problem. [0003] Furthermore, hearing aids typically perceive sound in such a way that the user perceives the source of the sound as being located within the head. Sound is said to be internalized rather than externalized. A common complaint of hearing aid users who are trying to understand speech in noise is that it is very difficult to follow everything that is being said, even though the sign...
