“…Minnaar et al (2001) studied localization accuracy with binaural recordings made with several artificial heads and reported continuous improvement over a period of five days. Honda et al (2007) reported that two weeks of game playing in an AVR substantially improved the players' AVR localization accuracy in both the horizontal and vertical planes. However, for studies demonstrating the effectiveness of practice on localization performance in AVR environments, the question arises as to what extent the observed improvements are the results of the practice itself and to what extent they are the effects of procedural learning and adaptation to the AVR environment (Hawkey et al 2004).…”

“…Most of the subjects reached the same level of localisation performance as their counterparts from the control group (who listened to 3D sounds filtered with individualised HRTFs) after performing several training sessions (Parseihian, Katz, 2012;Blum et al, 2004). Moreover, the training procedure proved to have long-term effects, as the listeners recorded similar levels of performance even one month after the experiment had taken place (Honda et al, 2007). In addition, the game-based training method helped the subjects to adapt to altered hearing conditions (the perception of 3D binaural sounds synthesised with non-individualised HRTFs in virtual auditory environments) and to recalibrate their spatial auditory representation while focusing on the most salient features of the incoming sound (Ohuchi et al, 2006).…”

“…In the majority of the studied experiments, the auditory recalibration procedure was based on proprioceptive feedback (Honda et al, 2013), audiovisual (Strelnikov et al, 2011;Shinn-Cunningham et al, 2005) and multimodal training (Blum et al, 2004), or 3D audio games (Honda et al, 2007;Blum et al, 2004). Most of the subjects reached the same level of localisation performance as their counterparts from the control group (who listened to 3D sounds filtered with individualised HRTFs) after performing several training sessions (Parseihian, Katz, 2012;Blum et al, 2004).…”

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 conditions. However, they depend on the anatomical characteristics of the human body and significantly vary among individuals, so that the use of the same dataset of HRTFs for all the users of a designed system will not offer the same level of auditory performance. This paper presents an alternative approach to the use on non-individualised HRTFs that is based on a procedural learning, training, and adaptation to altered auditory cues. We tested the sound localisation performance of nine sighted and visually impaired people, before and after a series of perceptual (auditory, visual, and haptic) feedback based training sessions. The results demonstrated that our subjects significantly improved their spatial hearing under altered listening conditions (such as the presentation of 3D binaural sounds synthesised from non-individualized HRTFs), the improvement being reflected into a higher localisation accuracy and a lower rate of front-back confusion errors.

“…As stated previously, within the sweep condition this lack of improvement may be due to participants ignoring the supplementary spatial cues once the front-back region was identified. In the case of the swing condition, perhaps localising performance was not improved given the absence of prior learning [16].…”

This study examined whether azimuth localising performance for non-individualised 3-D audio without integrated head tracking can be improved through the provision of supplementary reference signals. Twenty-two participants attempted to determine the location of spatial sounds developed through a non-individualised head-related transfer function (HRTF) while performing a visual distractor task. Localising sounds were randomly presented at 0-degrees elevation for each 10-degree increment about the azimuth. Three audio conditions were tested, two of which included different supplementary cues in the form of stationary and transient sounds that were spatially positioned to aid localising reference toward the midsagittal plane and interaural axis. The supplementary cues decreased errors in frontback perception; however, they did not significantly aid azimuth localising performance, and occasionally were reported to distract and disorient some participants. Supplementary audio cues have the potential to improve localising performance but should be more closely associated with the presented sound to lessen distraction and disorientation.
