    Vocal imitations and the identification of sound events

    International audienceIt is commonly observed that a speaker vocally imitates a sound that she or he intends to communicate to an interlocutor. We report on an experiment that examined the assumption that vocal imitations can e ffectively communicate a referent sound, and that they do so by conveying the features necessary for the identifi cation of the referent sound event. Subjects were required to sort a set of vocal imitations of everyday sounds. The resulting clusters corresponded in most of the cases to the categories of the referent sound events, indicating that the imitations enabled the listeners to recover what was imitated. Furthermore, a binary decision tree analysis showed that a few characteristic acoustic features predicted the clusters. These features also predicted the classi fication of the referent sounds, but did not generalize to the categorization of other sounds. This showed that, for the speaker, vocally imitating a sound consists of conveying the acoustic features important for recognition, within the constraints of human vocal production. As such vocal imitations prove to be a phenomenon potentially useful to study sound identifi cation

    Which words are most iconic?:Iconicity in English sensory words

    Some spoken words are iconic, exhibiting a resemblance between form and meaning. We used native speaker ratings to assess the iconicity of 3001 English words, analyzing their iconicity in relation to part-of-speech differences and differences between the sensory domain they relate to (sight, sound, touch, taste and smell). First, we replicated previous findings showing that onomatopoeia and interjections were highest in iconicity, followed by verbs and adjectives, and then nouns and grammatical words. We further show that words with meanings related to the senses are more iconic than words with abstract meanings. Moreover, iconicity is not distributed equally across sensory modalities: Auditory and tactile words tend to be more iconic than words denoting concepts related to taste, smell and sight. Last, we examined the relationship between iconicity (resemblance between form and meaning) and systematicity (statistical regularity between form and meaning). We find that iconicity in English words is more strongly related to sensory meanings than systematicity. Altogether, our results shed light on the extent and distribution of iconicity in modern English

    Sonic Skills

    It is common for us today to associate the practice of science primarily with the act of seeing—with staring at computer screens, analyzing graphs, and presenting images. We may notice that physicians use stethoscopes to listen for disease, that biologists tune into sound recordings to understand birds, or that engineers have created Geiger tellers warning us for radiation through sound. But in the sciences overall, we think, seeing is believing. This open access book explains why, indeed, listening for knowledge plays an ambiguous, if fascinating, role in the sciences. For what purposes have scientists, engineers and physicians listened to the objects of their interest? How did they listen exactly? And why has listening often been contested as a legitimate form of access to scientific knowledge? This concise monograph combines historical and ethnographic evidence about the practices of listening on shop floors, in laboratories, field stations, hospitals, and conference halls, between the 1920s and today. It shows how scientists have used sonic skills—skills required for making, recording, storing, retrieving, and listening to sound—in ensembles: sets of instruments and techniques for particular situations of knowledge making. Yet rather than pleading for the emancipation of hearing at the expense of seeing, this essay investigates when, how, and under which conditions the ear has contributed to science dynamics, either in tandem with or without the eye

    Investigating the spatial understanding of children who are blind through the use of the child's voice

    This thesis is intended to impact positively on our ability to understand and describe spatial awareness of children who are blind by investigating children’s explanations, understanding, feelings and coping strategies in their use of space in their everyday experience. It examines whether children who are blind are capable of providing reliable information that informs our knowledge of how they perceive space and how they achieve spatial understanding. The thesis also examines whether children’s voices inform the ideas, the theoretical perspectives and the positions adopted by researchers over the years that are found in the literature, in this complex field. The results are discussed in terms of their implications for the theoretical understanding of children’s experience of spatiality and the diversity of environmental circumstances to which they need to adapt. The results are also discussed in terms of their implications for practice by providing practitioners with theorized evidence of practice that supports the effective learning. Taken together, the evidence suggests that children who are blind are able to verbalize their knowledge about spatial relationships using a wide range of sensory and cognitive strategies and demonstrating a sophisticated understanding of space; thus suggesting that cognitive experiments may not be the only way to study spatial processing in children who are blind

    Soundscape mapping: comparing listening experiences

    The perceived auditory environment is an increasingly important part of people’s everyday interactive experiences. While sound design is an established discipline in media such as video games and cinema, this is not the case in Human-Computer Interaction (HCI). HCI designers are rarely trained in sound design, and may not make the most effective use of sound in the design of interactions. Even when sound is at the centre of a design it is rarely evaluated to compare the experiences of designers and listeners. This dissertation reports work conducted to develop a way of comparing sound designers’ intentions for a sound design with the experiences of listeners. Literature on methods of measuring, classifying and visualising sound was reviewed, as well as approaches to sound design in different forms of media and computing. A published method for representing auditory environments was selected for preliminary studies. The four studies addressed to the difficulties of describing auditory environments and how they might be visualised. Two surveys were conducted in order to identify attributes of sound that would be meaningful to 75 audio professionals and 40 listeners. A way of classifying and visualising sound events and their distribution in physical environments was developed and evaluated.The soundscape mapping tool (SMT) was trialled with sound designs from a range of fields within media and computing. The experiences of both the designer and listeners were captured for each of the designs using the SMT. This work demonstrated that the SMT was suitable for capturing the intentions of 10 sound designers and the experiences of 100 listeners. The trial also provided information about how the SMT could be developed further. The dissertation contributes evidence that auditory environments can be abstracted and visualised in a manner that allows designers to represent their designs, and listeners to record their experiences
