Abstract:
1. A method for generating a head related transfer function, comprising: measuring a plurality of impulse response for each individual of a sample group; for each individual of the sample group, converting each of the plurality of measured impulse responses to a set of head related transfer functions; averaging the sets of head related transfer functions for each of the individuals in the sample group to generate one average set of head related transfer functions; testing the average set of head related transfer functions to verify that it produces adequate sound for all members of a target population; wherein measuring each of the plurality of impulse responses comprises acquiring samples of a certain length using a certain sampling rate, and wherein the method further comprises, in the event that testing the average sets of head related functions does not verify that it produces adequate sound, adjusting the length of the samples and re-measuring the plurality of impulse responses for each individual of the sample group.
