Direct comparison of the impact of head tracking, reverberation, and individualized head-related transfer functions on the spatial perception of a virtual speech source.

چکیده
A study of sound localization performance was conducted using headphone-delivered virtual speech stimuli, rendered via HRTF-based acoustic auralization software and hardware, and blocked-meatus HRTF measurements. The independent variables were chosen to evaluate commonly held assumptions in the literature regarding improved localization: inclusion of head tracking, individualized HRTFs, and early and diffuse reflections. Significant effects were found for azimuth and elevation error, reversal rates, and externalization.

Use of Personalized Binaural Audio and Interactive Distance Cues in an Auditory Goal-reaching Task
While the angular spatialization of source sounds through individualized Head-related transfer functions (HRTFs) has been extensively investigated in auditory display research, also leading to effective real-time rendering of these functions, conversely the interactive simulation of egocentric distance information has received less attention. The latter, in fact, suffers from the lack of realti...
متن کاملDistance perception of a nearby virtual sound source reproduced by a linear loudspeaker array
When a virtual sound source is reproduced by a linear loudspeaker array, listeners can perceive not only the direction of the source, but also its distance. Control over perceived distance has often been implemented via the adjustment of various acoustic parameters, such as loudness, spectrum change, and the direct-to-reverberant energy ratio; however, there is a neglected yet powerful cue to t...
متن کاملEffect of Increasing System Latency on Localization of Virtual Sounds
In a virtual acoustic environment, the total system latency (TSL) refers to the time elapsed from the transduction of an event or action, such as movement of the head, until the consequences of that action cause the equivalent change in the virtual sound source. This paper reports on the impact of increasing TSL on localization accuracy when head motion is enabled. Five subjects estimated the l...
متن کاملMultimodal Perceptual Training for Improving Spatial Auditory Performance in Blind and Sighted Listeners
The use of individualised Head Related Transfer Functions (HRTF) is a fundamental prerequisite for obtaining an accurate rendering of 3D spatialised sounds in virtual auditory environments. The HRTFs are transfer functions that define the acoustical basis of auditory perception of a sound source in space and are frequently used in virtual auditory displays to simulate free-field listening condi...
متن کاملMeasurements of Sound Localization Performance and Speech Quality in the Context of 3D Audio Conference Calls
Teleconferencing solutions supporting 3D audio have two advantages. First, the talkers can be identified easily by locating their position in the virtual acoustic environment. Second, if multiple persons talk at the same time, humans can focus on the talker of their choice by taking advantage of the cocktail party effect. However, 3D audio lowers the speech quality by decreasing loudness and ad...
