Sensitivity analysis of pinna morphology on head-related transfer functions simulated via a parametric pinna model

Modeling Head-Related Transfer Functions Based on Pinna Anthropometry

The use of Head-Related Transfer Functions (HRTFs) in creating 3D sounds is gaining wide acceptance in multimedia applications. This paper presents a new method of modeling HRTFs based on the shape and size of the outer ear. Using signal processing tools, such as Prony’s signal modeling method, an appropriate set of time delays and a resonant frequency were used to approximate the measured Head...

On distance dependence of pinna spectral patterns in head-related transfer functions.

The aim of this letter is to address a little understood question in sound source localization: Can the distance of a near sound source affect our own perception of its elevation? The issue is studied by means of an objective analysis of a database of distance-dependent head-related transfer functions (HRTFs) of a KEMAR (Knowles Electronic Manikin for Acoustic Research) mannequin with different...

Frequency Estimation of the First Pinna Notch in Head-related Transfer Functions with a Linear Anthropometric Model

The relation between anthropometric parameters and Head-Related Transfer Function (HRTF) features, especially those due to the pinna, are not fully understood yet. In this paper we apply signal processing techniques to extract the frequencies of the main pinna notches (known as N1, N2, and N3) in the frontal part of the median plane and build a model relating them to 13 different anthropometric...

Arteriovenous malformation related to the pinna.

Arteriovenous malformations are rare in the head and neck region and generally arise from intracranial vessels. We present two rare cases with spontaneous arteriovenous malformations related to the ear. The role of magnetic resonance imaging and colour Doppler sonography in the diagnosis and management of such cases is discussed along with a review of the literature.
