Estimating headphone-to-ear transfer functions given parameters of headphones and external ears.
What is it about?
Headphone-to-ear transfer functions (HpTFs) vary considerably with headphones and listeners. Previously, in-ear measurements are needed to obtain HpTFs for various listener-headphone combinations, which is time consuming and inconvenient or impossible sometime. This paper shows that if parameters of the external ears of a listener and of a given headphone are known, then the HpTFs of the listener wearing that headphone can be calculated from these parameters, needless to require the listener to wear that headphone and to be tested on.
Why is it important?
HpTFs can be easily estimated through calculations for various listener-headphone combinations, without requiring in-ear measurements. The effects of different ear canals and headphones on the sound signals transmitted from headphones to eardrums can evaluated more accurately than using current standard ear simulators that have fixed acoustic structures and are unable to simulate individual differences in external ears.
