“…Nowadays, our ability to localise warns up other danger (cars when crossing a road) and helps us sort out individual speech from the usual background noise. One knows that localisation is mainly based upon interaural differences in intensity and spectrum, and upon interaural differences in arrival time of features of the direct sound waveform …”

Objective To perform a long‐term evaluation of the localisation capabilities in the horizontal plane of single‐sided deaf patients fitted with a BAHA device. Design Single‐centre retrospective study. Participants Twenty‐one adults with single‐sided deafness (SSD) with normal hearing in the contralateral ear (pure tone average <20 dB, SDS > 90%) rehabilitated with a Cochlear BAHA device from 2003 to 2012 on the deaf side over a median follow‐up of 8 years. Outcome measures The task used in this paper is a sound localisation identification task with a set‐up of seven loudspeakers on a semi‐circular array at 30‐degree intervals performed at three periods: before BAHA, initially and at last follow‐up. Our main criterion of judgement was the root‐mean‐square (RMS) localisation error. In addition, the Bern Benefit in Single‐Sided Deafness Questionnaire (BBSS) was administered. Results The mean RMS localisation error was initially estimated at 64° without any rehabilitation (for a chance level RMS estimated at 81°). Initially, with the BAHA device, the RMS localisation error dropped to 51°. At the last follow‐up evaluation, a significant decrease at 23° was noted. Concerning the Bern Questionnaire, 19% of the patients (n = 4) did not report any change (score of 0), 33% (n = 7) are satisfied (score of +1 or +2) and 48% (n = 10) are very satisfied with the BAHA device (score better than +3). Conclusion Improvement of sound localisation in the horizontal plane for some SSD patients is likely related to altered processing of monaural spectral cues. The time needed to learn to use the azimuth‐dependent spectral cues takes time. Long‐term follow‐up should be considered for studies investigating sound localisation performance.

“…Sound source position in the three-dimensional space is determined for a listener using horizontal plane azimuth, elevation in the vertical plane and distance depth. Horizontally, the azimuth is calculated with information arriving at both ears, using interaural time differences (ITD) and interaural intensity differences (IID) [44]. Interaural time difference (ITD) is a human mechanism that localises the source of sound on a horizontal plane, based on the difference between the nearest ear and the furthest ear away from the sound source [35].…”

“…Similar to ITD, interaural intensity difference (IID) is a mechanism that helps with the identification of a sound source position, however, it takes into account difference in sound source volume (intensity) between the ears [35]. Compared to ITD, IID provides better localisation for frequencies above 3 kHz [44].…”

“…Vertical localisation is a result of absorption, reflection and diffraction effects, caused by the pinna of the ear as well as the head, shoulders and chest [35,44]. These spectral cues are called head-related transfer functions or HRTFs and can vary greatly between individual people due to differences in the shape and size of the outer ear [44]. HRTF-based vertical sound localisation has been found to function monoaurally in humans for high frequency (more than 7 kHz) content [14].…”

This study interviewed game audio professionals to establish the implementation requirements for an experiment to ascertain the effect of different spatial audio localisation systems on the perception of threat in a first-person shooter. In addition, a listening study was carried out involving 35 members of the public, and using three scenes made in Unreal Engine 4 with custom designed sound, authored in Wwise. This established that spatial audio does, indeed, have a noticeable effect on players' perception of threat. Each spatial audio system, however, had different effects on the perception of threat, stealth, realism and position estimation, on all three different visual scenes. Meanwhile, the absence of spatial audio can confuse people and contribute towards inaccurate enemy localisation. With this in mind, a tailored approach to the game design requirements for each project is recommended. Rather than a single, spatialised design for the entire game, each scene should have its own design solution.
