This paper concerns the use of a simple head-and-torso model to correct deficiencies in the low-frequency behavior of experimentally measured head-related transfer functions (HRTFs). This so-called \snowman'' model consists of a spherical head locate

The head-related transfer function (HRTF) for distant sources is a complicated function of azimuth, elevation and frequency. This paper presents simple geometric models of the head and torso that provide insight into its low-frequency behavior, espec

The analysis and modeling of the response of parts of the body provides valuable insight into many features of the head-related transfer function (HRTF). In spatial sound simulations, partial models, such as the spherical head model, can also generat

An optimal spherical-head model is derived from the high-frequency interaural time difference (ITD) of a population of 25 subjects. Analysis demonstrates that the optimal sphere results in a very small lateral angle errors, except near5 the interaura

Conventional mean squared error based methods for objective image quality assessment are not well correlated with human evaluation. The design of better objective measures of quality has attracted a lot of attention and several image quality metrics

We show how the contralateral head-related transfer function (HRTF) can be modeled by a simple transformation of the ipsilateral HRTF. Components of the transformation are based on a spherical model of the listener's head. Listening tests reveal that

Head Related Transfer Functions (HRTF's) characterize the transformation of pressure waves from the sound source to the listener's eardrums. They are of central interest to binaural hearing and to sound localization. The HRTF is a function of the azi
