Abstract

The present invention relates to systems and methods for determining heat related transfer functions. A method for determining HRTF includes obtaining a plurality of reference images of different respective ears, one or more of the reference images associated with a corresponding pre-determined HRTF information, obtaining information regarding an input image that includes an image of an ear of a subject, comparing the information regarding the input image with information regarding the reference images using a processor, and selecting one of the pre-determined HRTF information based at least in part on a result of the act of comparing.

Description

[0001] relevant application data [0002] This application claims priority and benefit from pending Danish Patent Application No. PA201101008 filed on December 30, 2011, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present application relates generally to spatial hearing, and more particularly, to systems and methods for determining head related transfer functions (HRTF). Background technique [0004] Spatial hearing involves measuring the HRTF of the subject being fitted. Determining HRTFs is a difficult task, and existing techniques for determining HRTFs are very time-consuming, expensive, and cumbersome. HRTF is typically measured in an anechoic chamber as a transfer function from a sound source positioned at various horizontal and vertical angles from the subject to a small microphone positioned close to the subject's eardrum. Acquire many measurement positions for accurate HRTF measurements. [0005] The applicants ...
