5. Hearing distance: A low-cost model for near-field binaural effects.

Abstract

An extremely low-order filter model for source distance rendering in binaural reproduction is proposed in this paper. The main purpose of such model is to cheaply simulate the effect that source-listener distance has on the sound waves arriving at the ears in the near field, a region where the relation between sound pressure and distance is both highly frequency-dependent and nonlinear. The reference for the model is based on an analytical description of a spherical head response, appropriately filtered out so as to include distance-dependent patterns only. To this regard, the model is objectively seen to provide an excellent fit in the whole near field, despite its simplicity. [ABSTRACT FROM PUBLISHER]

Abstract

Purpose The paper presents a system for customized binaural audio delivery based on the extraction of relevant features from a 2-D representation of the listener's pinna. Design/methodology/approach The most significant pinna contours are extracted by means of multi-flash imaging, and they provide values for the parameters of a structural head-related transfer function (HRTF) model. The HRTF model spatializes a given sound file according to the listener's head orientation, tracked by sensor-equipped headphones, with respect to the virtual sound source. Findings A preliminary localization test shows that the model is able to statically render the elevation of a virtual sound source better than non-individual HRTFs. Research limitations/implications Results encourage a deeper analysis of the psychoacoustic impact that the individualized HRTF model has on perceived elevation of virtual sound sources. Practical implications The model has low complexity and is suitable for implementation on mobile devices. The resulting hardware/software package will hopefully allow an easy and low-tech fruition of custom spatial audio to any user. Originality/value We show that custom binaural audio can be successfully deployed without the need of cumbersome subjective measurements. [ABSTRACT FROM AUTHOR]
