Auditory distance perception plays a major role in spatial awareness, enabling location of objects and avoidance of obstacles in the environment. However, it remains under-researched relative to studies of the directional aspect of sound localization. This review focuses on the following four aspects of auditory distance perception: cue processing, development, consequences of visual and auditory loss, and neurological bases. The several auditory distance cues vary in their effective ranges in peripersonal and extrapersonal space. The primary cues are sound level, reverberation, and frequency. Nonperceptual factors, including the importance of the auditory event to the listener, also can affect perceived distance. Basic internal representations of auditory distance emerge at approximately 6 months of age in humans. Although visual information plays an important role in calibrating auditory space, sensorimotor contingencies can be used for calibration when vision is unavailable. Blin...

Purpose: This paper systematically reviews the literature to
determine if improving the signal-to-noise ratio (SNR) im-
proves classroom performance in students with autism spec-
trum disorder (ASD).
Methods: Six databases were searched for the terms acoustics,
signal-to-noise ratio, classroom and ASD. Five studies were
found that met the selection criteria.
Results: All five studies reported improving the SNR benefit-
ted students with ASD in the classroom. Benefits included
improved listening behaviours, increased on-task behaviours,
improved speech recognition and reduced listening stress.
Conclusion: The evidence is suggestive that improving the
SNR improves classroom performance in students with
ASD. Limitations included the small number of studies and
limited range of technologies considered. Further research
should consider other technologies that could mitigate tactile
sensitivities present in some students with ASD.

Temporal order judgment (TOJ) thresholds have been widely reported as valid estimates of the temporal disparity necessary for correctly identifying the order of two stimuli. Data for two auditory TOJ paradigms are often reported in the literature: (1) spatially-based TOJ in which the order of presentation of the same stimulus to the right and left ear differs; and (2) spectrally-based TOJ in which the order of two stimuli differing in frequency is presented to one ear or to both ears simultaneously. Since the thresholds reported using the two paradigms differ, the aim of the current study was to compare their response patterns. The results from three different experiments showed that: (1) while almost none of the participants were able to perform the spatial TOJ task when ISI = 5 ms, with the spectral task, 50% reached an accuracy level of 75% when ISI = 5 ms; (2) temporal separation was only a partial predictor for performance in the spectral task, while it fully predicted performa...

This research was carried out as part of the French national multidisciplinary research project, PREDIT-SARI. Using a driving simulator, it aimed to test the effectiveness of road treatments intended to inform drivers about the risk of losing control on rural roads with “crest vertical curves” (Landis et al., 2004). [Rosey, F., Auberlet, J.M., Bertrand, J., Plainchault, P., 2008. Impact of perceptual treatments on lateral control during driving on crest vertical curves: a driving simulator study. Accid. Anal. Prev. 40, 1515–1523, Scopus.] used a fixed-base driving simulator to test four perceptual treatments intended to help drivers maintain lateral control when driving on crest vertical curves and found that two of them, rumble strips on both sides of the centerline and sealed shoulders, were more effective than the others. This first study prompted us to ask if non-visual sensory cues (e.g., vestibular or proprioceptive perceptions) could influence driver perception and consequently lateral control. We therefore conducted a second study on a motion-base driving simulator, using the same virtual 3D database. The results showed that: (1) drivers drive closer to the center of their lane when there are rumble strips on both sides of the centerline, or when there are sealed shoulders, than they do with the current marking system (i.e., continuous lines), and (2) the impact of the two tested perceptual treatments was replicated on both types of driving simulator.

The essay investigates the usefulness for semiotic disciplines of comparing its heuristic results with those of the scientific and experimental disciplines, without exceeding its theoretical limits. The starting point comes from the affirmation of U. Eco about the opportunity for semiologists to “do not poke their noses into the black box of mind or brain processes”. As a boundary matter on which semiotics is confronted with other disciplines, is then examined the issue of perception, particularly the auditory one, taking into account some explanatory models proposed around cognitive psychology and neuroscience. Specifically, a brief analysis of the problems related to the perceptual recognition of sound is performed, compared to the visual, focusing the attention, also through textual examples, on the role of sound in the audiovisual language. Among auditory perception description models, here are mentioned the “Auditory Scene Analysis” by A. Bregman, and theories related to the “auditory object”, highlighting similarities and divergences with respect to how Eco considers the problem of perception.
Il saggio indaga l’utilità per le discipline semiotiche di porre a confronto i propri risultati euristici con quelli delle discipline scientifiche e sperimentali, senza oltrepassare i propri limiti teorici. Lo spunto iniziale parte dall’affermazione di U. Eco sull’opportunità per i semiologi di “non mettere il naso nella scatola nera dei processi mentali o cerebrali”. Come materia di confine sulla quale la semiotica si confronta con altre discipline viene quindi affrontato il tema della percezione, in particolare quella uditiva, passando in rassegna alcuni modelli esplicativi proposti nell’ambito della psicologia cognitiva e delle neuroscienze. Nello specifico, viene compiuta una breve ricognizione dei problemi relativi al riconoscimento percettivo del suono, comparati al campo visivo, focalizzando l’attenzione, anche attraverso esempi testuali, sul ruolo del suono nel linguaggio audiovisivo. Tra i modelli di descrizione della percezione uditiva vengono menzionati la “Auditory Scene Analysis” di A. Bregman e le teorie relative all’ “oggetto uditivo”, evidenziando analogie e divergenze rispetto alla trattazione del problema della percezione per come viene operato da Eco.

Cross-modal binding in auditory-visual speech perception was investigated by using the McGurk effect, a phenomenon in which hearing is altered by incongruent visual mouth movements. We used functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). In each experiment, the subjects were asked to identify spoken syllables (‘ba’, ‘da’, ‘ga’) presented auditorily, visually, or audiovisually (incongruent stimuli). For the
