People can discriminate the synchrony between audio-visual scenes. However, the sensitivity of audio-visual synchrony perception can be affected by many factors. Using a simultaneity judgment task, the present study investigated whether the synchrony perception of complex audio-visual stimuli was affected by audio-visual causality and stimulus reliability. In Experiment 1, the results showed that audio-visual causality could increase one's sensitivity to audio-visual onset asynchrony (AVOA) of both action stimuli and speech stimuli. Moreover, participants were more (...) tolerant of AVOA of speech stimuli than that of action stimuli in the high causality condition, whereas no significant difference between these two kinds of stimuli was found in the low causality condition. In Experiment 2, the speech stimuli were manipulated with either high or low stimulus reliability. The results revealed a significant interaction between audio-visual causality and stimulus reliability. Under the low causality condition, the percentage of “synchronous” responses of audio-visual intact stimuli was significantly higher than that of visual_intact/auditory_blurred stimuli and audio-visual blurred stimuli. In contrast, no significant difference among all levels of stimulus reliability was observed under the high causality condition. Our study supported the synergistic effect of top-down processing and bottom-up processing in audio-visual synchrony perception. (shrink)

In the Internet age, information security is threatened anytime and anywhere and the copyright protection of audio and video as well as the need for matching detection is increasingly strong. In view of this need, this paper proposes a zero-watermarking algorithm for audio and video matching based on NSCT. The algorithm uses NSCT, DCT, SVD, and Schur decomposition to extract video features and audio features and generates zero-watermark stream through synthesis, which is stored in a third-party organization (...) for detection and identification. The detection algorithm can obtain zero watermark from the audio and video to be tested and judge and locate tampering by comparing with the zero watermark of the third party. From the experimental results, this algorithm can not only detect whether the audio and video are mismatched due to tampering attacks but also locate the mismatched audio and video segments and protect the copyright.

IntroductionThe idea of video recording in the operating room with panoramic cameras and microphones is a new concept that is changing the approach to medical activities in the OR. However, VR in the OR has brought up many concerns regarding patient privacy and has highlighted legal and ethical issues that were never previously exposed.AimTo review the literature concerning these aspects and provide a better ethical and legal understanding of the new challenges concerning VR in the OR.ConclusionsThere is a disparity between (...) the two main legal models concerning VR in the OR, namely the European legal system ) and the American legal framework ). This difference mainly deals with two distinct bioethical paradigms: GDPR places a strong emphasis on protecting patients’ privacy to improve the public health system, whereas HIPAA indicates the need to generate protocols to safeguard the risks connected to medical activity and patient privacy. Following from this point, we may argue that, at the ethical and bioethical level, GDPR and HIPAA depend mainly on two different ethical models: a perspective based on moral acquaintances and weak proceduralism, respectively. It is worth noting the importance of developing additional guidelines concerning different world regions to avoid the ethical problems that may emerge when simply applying a foreign paradigm to a very different culture.

In lieu of an abstract, here is a brief excerpt of the content:Reading Audio BooksWilliam IrwinI hide my audio book habit because most of my colleagues, and even some of my snobbier students, regard audio books as a sign of an impending dark age of mass illiteracy. Feeling uneasy, I wonder: when The Brothers Karamazov comes up in conversation am I obliged to "confess" that I listened to the unabridged audio book, but did not silently read (...) the massive tome? Is there a difference that makes a difference between listening to an audio book and reading a printed book?IPeople read less today, partly because reading silently is not social; we crave the company of loved ones at the end of the day, and so prefer to watch television with them. Silent reading does not fit today's multitasking lifestyle; you can listen to music while you drive or jog, but you cannot read a book. Or, then again, perhaps you can, if listening to an audio book is reading after all. Time does not need to be specifically set aside for an audio book the way it does with a conventional book—the lights don't even have to be on. And surprisingly, it is satisfying to listen to a book ten minutes at a time while running errands. Perhaps this is because getting started is as easy as pressing a button. By contrast, few people read printed books in ten minute blocks, presumably because it takes something for most people to warm up to reading. If they are going to read, then they are going to do it for a sustained time—something longer than a ten-minute block. It is easier to "push through" and finish an audio book. I nearly gave up on Catch-22; it's too thick and over the top with satire for my taste. And I surely would have given up on it if I had been reading the book silently. I stuck with [End Page 358] the audio book, however, largely because it was easy to continue; I just pressed play every time I got in my car.Books on tape have been available for quite some time, but, despite often being abridged, they were too clunky and cumbersome for most people. The availability of books on CD and for MP3 download makes it all much more convenient. Audio books are now the fastest growing segment of the book industry and are likely to become even more common and popular, perhaps some day eclipsing the sale of conventional books, perhaps some day becoming the normal way of "reading" literature. And far from being abridged, some audio books today include extras. For example, the audio version of The Amber Spyglass includes epigrams before each chapter that are not in the print version.IIHarold Bloom says, "Deep reading really demands the inner ear as well as the outer ear. You need the whole cognitive process, that part of you which is open to wisdom. You need the text in front of you."1 Before listening to audio books myself I would have agreed with Bloom; but now I suspect he simply has never listened to an audio book. Skeptical of literature on audio, I started my audio experience with nonfiction. Pleasantly surprised with nonfiction, I tried listening to fiction and found the presentation very different. Nonfiction books are simply read, whereas works of fiction are typically performed—characters get distinct voices and the reader really puts on a show. Most audio book performances of literature are much like a one-man play, taking us back to the days of traveling bards and rhapsodes.In The Performance of Reading Peter Kivy highlights that for most of its history Western literature has been experienced out loud.2 As is well known, Homer's Iliad and Odyssey were performed out loud by bards, as Beowulf was centuries later. But less well known is the fact that even after the invention of the printing press, when books were still scarce and expensive, even people in possession of books generally read them out loud to themselves and to others. So it is odd that along with Harold Bloom, my colleagues and students, look with mistrust at... (shrink)

We examined whether facial expressions of performers influence the emotional connotations of sung materials, and whether attention is implicated in audio-visual integration of affective cues. In Experiment 1, participants judged the emotional valence of audio-visual presentations of sung intervals. Performances were edited such that auditory and visual information conveyed congruent or incongruent affective connotations. In the single-task condition, participants judged the emotional connotation of sung intervals. In the dual-task condition, participants judged the emotional connotation of intervals while performing (...) a secondary task. Judgements were influenced by melodic cues and facial expressions and the effects were undiminished by the secondary task. Experiment 2 involved identical conditions but participants were instructed to base judgements on auditory information alone. Again, facial expressions influenced judgements and the effect was undiminished by the secondary task. The results suggest that visual aspects of music performance are automatically and preattentively registered and integrated with auditory cues. (shrink)

Audio description remains the cornerstone of accessibility for visually impaired audiences to all sorts of audiovisual content, including porn. Existing work points to the efficacy of audio description to guarantee immersion and emotional engagement, but evidence on its role in sexual arousal and engagement in porn is still scant. The present study takes on this challenge by comparing sighted and visually impaired participants’ experiences with porn in terms of their physiological response [i.e., cortisol and heart rate ] and (...) self-report measures of affect [Positive and Negative Affect Schedule ; Watson et al., 1988], anxiety [State-Trait Anxiety Inventory ; Spielberger et al., 1970], sexual reactivity and arousal [Sexual Inhibition/Sexual Excitation Scale ; Moyano and Sierra ; and the Ratings of Sexual Arousal ; Mosher ], and narrative engagement or transportation [The Transport Narrative Questionnaire, Green and Brock ]. 69 Spanish participants were allocated into three different groups: 25 sighted participants who watched and heard the porn scenes in their audio-visual version ; 22 sighted participants who listened to the audio described version without images ; and 22 visually impaired participants who also listened to the audio described version without images. Overall, results on physiological and self-report measures revealed no significant differences between groups or different versions of the clips. The analysis of cortisol reactivity to porn as the maximum increase or decrease in cortisol with respect to baseline values revealed no significant differences between the groups, but pointed to a higher percentage of non-responders than responders in the three groups, the highest being found in the ONCE group. As for participants’ cardiac response to the clips, no significant differences were found across the groups, with the highest HR levels being registered in the baseline phase. Self-report measures revealed significant between-group differences in negative affect. The ONCE group displayed the highest pre-task levels of negative affect and was the only group that showed a decrease in negative affect after exposure to the clips. Sighted and visually impaired participants reported to be moderately aroused and immersed in the films, regardless of exposure to AV or AD porn. In addition, correlations found between participants’ levels of self-report sexual arousal and transportation and post-task affect pointed to a positive relationship between exposure to porn and perceived levels of sexual arousal and affect. Results from the study reflected the efficacy of audio description in providing sighted and visually impaired audiences with a similar experience to that offered by original AV porn scenes. This study is exploratory but provides valid, initial groundwork for further research on the impact of audio description on porn reception. (shrink)

Experimental research has shown that pairs of stimuli which are congruent and assumed to 'go together' are recalled more effectively than an item presented in isolation. Will this multisensory memory benefit occur when stimuli are richer and longer, in an ecological setting? In the present study, we focused on an everyday situation of audio-visual learning and manipulated the relationship between audio guide tracks and viewed portraits in the galleries of the Tate Britain. By varying the gender and narrative (...) style of the voice-over, we examined how the perceived congruency and assumed unity of the audio guide track with painted portraits affected subsequent recall. We show that tracks perceived as best matching the viewed portraits led to greater recall of both sensory and linguistic content. We provide the first evidence that manipulating crossmodal congruence and unity assumptions can effectively impact memory in a multisensory ecological setting, even in the absence of precise temporal alignment between sensory cues.

In this paper we offer a theory of cross-modal objects. To begin, we discuss two kinds of linkages between vision and audition. The first is a duality. The the visual system detects and identifies surfaces ; the auditory system detects and identifies sources . Surfaces are illuminated by sources of light; sound is reflected off surfaces. However, the visual system discounts sources and the auditory system discounts surfaces. These and similar considerations lead to the Theory of Indispensable Attributes that states (...) the conditions for the formation of gestalts in the two modalities. The second linkage involves the formation of audiovisual objects, integrated cross-modal experiences. We describe research that reveals the role of cross-modal causality in the formation of such objects. These experiments use the canonical example of a causal link between vision and audition: a visible impact that causes a percussive sound. (shrink)

This article investigates the hypothesis of creating non-linear audio-visual narratives, through an unanticipated use of traditional print-based games, enriched with videos, via augmented reality (AR) possibilities. A ludic system has been created and presented. Based on a traditional card game, a non-linear cinematic narrative occurs. We attempt to examine the following questions: in which way can we bring together different forms of visual communication, such as graphic design and video? Can the above forms create a complex narrative whole and (...) what kind of rules will be needed for this? How can we enrich traditional forms of gaming with the potentials of AR? Gaming itself demands a set of rules. Can these rules play the role of algorithms in the combined universe that we have designed and created? In which way can the designer on the one hand and the user on the other influence the overall output of the system? What will the user experience be like? The printed card system chosen for this is Tarot and more precisely the Great Arcana, which makes use of the 22 fundamental Tarot figures. (shrink)

Previous research with speech and non-speech stimuli suggested that in audiovisual perception, visual information starting prior to the onset of corresponding sound can provide visual cues, and form a prediction about the upcoming auditory sound. This prediction leads to audiovisual interaction. Auditory and visual perception interact and induce suppression and speeding up of the early auditory event-related potentials such as N1 and P2. To investigate AV interaction, previous research examined N1 and P2 amplitudes and latencies in response to audio (...) only, video only, audiovisual, and control stimuli, and compared AV with auditory perception based on four AV interaction models. The current study addresses how different models of AV interaction express N1 and P2 suppression in music perception. Furthermore, the current study took one step further and examined whether previous musical experience, which can potentially lead to higher N1 and P2 amplitudes in auditory perception, influenced AV interaction in different models. Musicians and non-musicians were presented the recordings of a keyboard /C4/ key being played, as well as CO stimuli. Results showed that AV interaction models differ in their expression of N1 and P2 amplitude and latency suppression. The calculation of model and has consequences for the resulting N1 and P2 difference waves. Furthermore, while musicians, compared to non-musicians, showed higher N1 amplitude in auditory perception, suppression of amplitudes and latencies for N1 and P2 was similar for the two groups across the AV models. Collectively, these results suggest that when visual cues from finger and hand movements predict the upcoming sound in AV music perception, suppression of early ERPs is similar for musicians and non-musicians. Notably, the calculation differences across models do not lead to the same pattern of results for N1 and P2, demonstrating that the four models are not interchangeable and are not directly comparable.

We investigate whether smile mimicry and emotional contagion are evident in non-text-based computer-mediated communication (CMC). Via an ostensibly real-time audio-visual CMC platform, participants interacted with a confederate who either smiled radiantly or displayed a neutral expression throughout the interaction. Automatic analyses of expressions displayed by participants indicated that smile mimicry was at play: A higher level of activation of the facial muscle that characterises genuine smiles was observed among participants who interacted with the smiling confederate than among participants who (...) interacted with the unexpressive confederate. However, there was no difference in the self-reported level of joviality between participants in the two conditions. Our findings demonstrate that people mimic smiles in audio-visual CMC, but that even though the diffusion of emotions has been documented in text-based CMC in previous studies, we find no convincing support for the phenomenon of emotional contagion in non-text-based CMC.

It is commonly believed that human perceptual experiences can be, and usually are, multimodal. What is more, a stronger thesis is often proposed that some perceptual multimodal characters cannot be described simply as a conjunction of unimodal phenomenal elements. If it is the case, then a question arises: what is the additional mode of combination that is required to adequately describe the phenomenal structure of multimodal experiences? The paper investigates what types of audio–visual experiences have phenomenal character that cannot (...) be analysed as a mere conjunction of visual and auditory elements; and how can we properly characterise the required, additional mode of perceptual combination. Three main modes of combination are considered: instantiation, parthood, and grouping. It is argued that some phenomena involving intermodal relations, like spatial and temporal ventriloquism, can be analysed in terms of audio–visual, perceptual grouping. On the other hand, cases of intermodal binding need a different treatment. Experiences involving audio–visual binding should be analysed as experiences presenting objects or events which instantiate, or which have a proper part instantiating, both visually and auditorily determined properties.

Following Cass Sunstein's popular treatment of the concept, echo chambers are often defined as environments which exclude contrary opinions through omission. C. Thi Nguyen contests the popular usage and defines echo chambers in terms of in-group trust and out-group distrust. In this paper, I argue for a more comprehensive treatment. While both exclusion by omission and out-group distrust help sustain echo chambers, neither defines the phenomenon. I develop a social network model of echo chambers which focuses on the role of (...) belief-reinforcing echoes. First, I argue that the model allows us to incorporate Nguyen's main point about distrust without construing other commentators as deeply mistaken about the nature of echo chambers. Second, I use the model to develop an account of collaborative resistance and use it to clarify the role echo chambers play in spreading misinformation. (shrink)

This article argues that errors in audio data processing should be examined to explore and expose the underlying components that enable linguistic communication and cross-cultural understanding. Examples of errors in the transcription of a Mexican social network’s conversations are analyzed to demonstrate the potential of such data in the development of sociocognitive language-processing theories. It is suggested that researchers working with audio-recorded data should expand the scope of what is considered useful data for the sake of both methodological (...) reflexivity and identifying the underlying cognitive processes enabling linguistic understanding.

Podcasts have been described as “a cinema for the ears” and this application of a visual rhetoric to describe an audio-only experience results in an attempt to define what is still a relatively new medium. I argue that it is possible to consider something cinematic without the presence of moving images. Assertions in favour of the cinematic nature of podcasts often employ the visual imagination of listeners evoked by heightened audio characteristics that a particular podcast may possess. By (...) focusing on film-centred podcasts specifically, which, in terms of content and form, are implicitly and often explicitly concerned with properties of the cinematic, I argue for a more conceptual analysis of the idea of a visual form of audio. While many film-oriented podcasts provide a supplementary celebration of cinema culture rather than manifesting a unique cinematic experience of their own, there are examples of film-centred podcasts that attempt to actualise what I will call an “audio-cinematic” experience, deploying the creative potential of the podcast to manifest an experiential aura that evokes a cinematic imagination. I analyse the sonic dimensions of audio-cinematic podcasts including my work with Neil Fox on The Cinematologists Podcast. (shrink)

Audio features such as inharmonicity, noisiness, and spectral roll-off have been identified as correlates of “noisy” sounds. However, such features are likely involved in the experience of multiple semantic timbre categories of varied meaning and valence. This paper examines the relationships of stimulus properties and audio features with the semantic timbre categories raspy/grainy/rough, harsh/noisy, and airy/breathy. Participants rated a random subset of 52 stimuli from a set of 156 approximately 2-s orchestral instrument sounds representing varied instrument families, registers, (...) and both traditional and extended playing techniques. Stimuli were rated on the three semantic categories of interest, as well as on perceived playing exertion and emotional valence. Correlational analyses demonstrated a strong negative relationship between positive valence and perceived physical exertion. Exploratory linear mixed models revealed significant effects of extended technique and pitch register on valence, the perception of physical exertion, raspy/grainy/rough, and harsh/noisy. Instrument family was significantly related to ratings of airy/breathy. With an updated version of the Timbre Toolbox, we used 44 summary audio features, extracted from the stimuli using spectral and harmonic representations, as input for various models built to predict mean semantic ratings for each sound on the three semantic categories, on perceived exertion, and on valence. Random Forest models predicting semantic ratings from audio features outperformed Partial Least-Squares Regression models, consistent with previous results suggesting that non-linear methods are advantageous in timbre semantic predictions using audio features. Relative Variable Importance measures from the models among the three semantic categories demonstrate that although these related semantic categories are associated in part with overlapping features, they can be differentiated through individual patterns of audio feature relationships.

Lip reading is the ability to partially understand speech by looking at the speaker's lips. It improves the intelligibility of speech in noise when audio-visual perception is compared with audio-only perception. A recent set of experiments showed that seeing the speaker's lips also enhances sensitivity to acoustic information, decreasing the auditory detection threshold of speech embedded in noise [J. Acoust. Soc. Am. 109 (2001) 2272; J. Acoust. Soc. Am. 108 (2000) 1197]. However, detection is different from comprehension, and (...) it remains to be seen whether improved sensitivity also results in an intelligibility gain in audio-visual speech perception. In this work, we use an original paradigm to show that seeing the speaker's lips enables the listener to hear better and hence to understand better. The audio-visual stimuli used here could not be differentiated by lip reading per se since they contained exactly the same lip gesture matched with different compatible speech sounds. Nevertheless, the noise-masked stimuli were more intelligible in the audio-visual condition than in the audio-only condition due to the contribution of visual information to the extraction of acoustic cues. Replacing the lip gesture by a non-speech visual input with exactly the same time course, providing the same temporal cues for extraction, removed the intelligibility benefit. This early contribution to audio-visual speech identification is discussed in relationships with recent neurophysiological data on audio-visual perception. (shrink)

Despite a predominantly digital, 21st century music production landscape, analogue hardware professional audio technologies persist. In the discoursal throes of the leading online audio technology message forum Gearslutz, such technologies are routinely objectified, sexualized, fetishized and socialized into gear. Situated in a contemporary critical, interdisciplinary framework of fetish, masculinity and sexuality studies, this research interrogates how audio technologies manufactured and intended for music production contexts become sexy. Applying a mixed-mode methodology, including an intensive discourse, image and material-semiotic (...) analysis of an ‘epic’ sexy gear thread, we collated extensive data about technological fetishization. Sexy gear discourse articulates themes of voyeurism, acquisition, control and animation – linking the fetish value of technological objects and their connoisseurship with the erotic potential of sexualized objects. Such discourses ultimately serve to maintain social order, and become sites for performing the maintenance work of hegemonic masculine formations. This research provides new insights into how hegemonic masculinities depend upon the organization of online and offline sociability around fetishized material objects. Furthermore, our findings align with those of current scholarship focused on representational politics of technoculture. (shrink)

Utilizing a pre-experimental pre-test post-test design, this study investigated the effect of an authentic audio-visual American sitcom on the intercultural sensitivity and intercultural effectiveness of a sample of male and female upper-intermediate English students. To this aim, 34 Iranian EFL students were selected through convenient non-random sampling.

Over a 10-week period, the participants were presented with (...) nearly 30-min-long episodes of Friends in a flipped context, two episodes every week uploaded to the accompanying website. An online 10-item quiz on the day of watching and a next-day meeting were held. During the online discussion meetings, the participants discussed cultural questions tailored to the aims of the study. The required data were collected through the administration of the intercultural sensitivity scale and intercultural effectiveness scale in pre- and post-test assessments. The analyses of the data indicated that both ICS and ICE improved significantly during the intervention. However, ICS indicated more improvement. In addition, a semi-structured interview was administered to the participants to examine their perception of the flipped classroom experience. Having analyzed the data using MAXQDA 2020, some significant themes emerged which are reported. On the whole, the participants portrayed positive attitudes toward using technology in flipped classes.

Assistive Device Art derives from the integration of Assistive Technology and Art, involving the mediation of sensorimotor functions and perception from both, psychophysical methods and conceptual mechanics of sensory embodiment. This paper describes the concept of ADA and its origins by observing the phenomena that surround the aesthetics of prosthesis-related art. It also analyzes one case study, the Echolocation Headphones, relating its provenience and performance to this new conceptual and psychophysical approach of tool design. This ADA tool is designed to (...) aid human echolocation. They facilitate the experience of sonic vision, as a way of reflecting and learning about the construct of our spatial perception. Echolocation Headphones are a pair of opaque goggles which disable the participant’s vision. This device emits a focused sound beam which activates the space with directional acoustic reflection, giving the user the ability to navigate and perceive space through audition. The directional properties of parametric sound provide the participant a focal echo, similar to the focal point of vision. This study analyzes the effectiveness of this wearable sensory extension for aiding auditory spatial location in three experiments; optimal sound type and distance for object location, perceptual resolution by just noticeable difference, and goal-directed spatial navigation for open pathway detection, all conducted at the Virtual Reality Lab of the University of Tsukuba, Japan. The Echolocation Headphones have been designed for a diverse participant base. They have both the potential to aid auditory spatial perception for the visually impaired and to train sighted individuals in gaining human echolocation abilities. Furthermore, this Assistive Device artwork instigates participants to contemplate on the plasticity of their sensorimotor architecture. (shrink)

During the COVID-19 pandemic, questions have been raised about the impact of face masks on communication in classroom settings. However, it is unclear to what extent visual obstruction of the speaker’s mouth or changes to the acoustic signal lead to speech processing difficulties, and whether these effects can be mitigated by semantic predictability, i.e., the availability of contextual information. The present study investigated the acoustic and visual effects of face masks on speech intelligibility and processing speed under varying semantic predictability. (...) Twenty-six children and twenty-six adults performed an internet-based cued shadowing task, in which they had to repeat aloud the last word of sentences presented in audio-visual format. The results showed that children and adults made more mistakes and responded more slowly when listening to face mask speech compared to speech produced without a face mask. Adults were only significantly affected by face mask speech when both the acoustic and the visual signal were degraded. While acoustic mask effects were similar for children, removal of visual speech cues through the face mask affected children to a lesser degree. However, high semantic predictability reduced audio-visual mask effects, leading to full compensation of the acoustically degraded mask speech in the adult group. Even though children did not fully compensate for face mask speech with high semantic predictability, overall, they still profited from semantic cues in all conditions. Therefore, in classroom settings, strategies that increase contextual information such as building on students’ prior knowledge, using keywords, and providing visual aids, are likely to help overcome any adverse face mask effects.
