Getrocknete Stimmen. Menschen mit Behinderung benutzen Kassettenrekorder

Der Autor stellt drei Thesen zu der Fragestellung „Wie gehen Jugendliche und junge Erwachsene alltagstauglich mit dem Kassettenrekorder um?“ auf, die er in drei Anläufen begründet: „Es geht zunächst um Alltag und wie sich Menschen mit Benachteiligungen und Behinderung darin bewegen. In einem zweiten Anlauf [skizziert er] kurz die gegenwärtigen sonderpädagogische Fragestellungen und deren Aufmerksamkeit für das Hören und Zuhören … [Daraus] soll deutlich werden, wie man mit O-Tönen Sollbruchstellen herstellen kann, und wie sich eine solche Praxis begründen lässt.“ Indem junge Menschen mit Behinderung mit Audiorekordern ihren Alltag erkunden, kehrt sich durch die Erkundungsform Interview die bisher erlebte asymmetrische Kommunikationssituation um, weil selbst über Inhalt, Anfang und Ende einer Kommunikation bestimmt werden kann. Somit begründen Audioclips Erfahrung von Kommunikationssouveränität. (Orig./Autor)

Hör-Spiele/Laut-Sprecher. Aspekte medialer Hörerziehung an der Schule für Geistigbehinderte

Sonderpädagogisch orientierter Unterricht thematisiert Hören auf dreierlei Weise: Innerhalb von Artikulationsförderung (Lautproduktion) geht es um die Unterscheidung, Wiederholung einzelner Phoneme oder Phonemgruppen, deren Zusammenbinden zu Wörtern, Sätzen usw. und damit um Aufbau und Stabilisierung auditiv-motorischer Regulationskreise bei der Sprachproduktion. In der Wahrnehmungsförderung geht es um Unterscheidung und Benennung von Klängen oder Geräuschen. Ansätze der Medienerziehung heben den Unterschied konservierter/vermittelter und tatsächlicher Klangereignisse hervor. In allen drei Perspektiven geht es um die Ausbildung, Verbesserung, Schulung des Hörorgans und der darauf bezogenen kognitiven und sprachlichen Leistungen. Was dabei allerdings vernachlässigt bleibt ist der ursprüngliche Weltbezug des Hörens. Denn wir hören nicht an sich, sondernd stets irgendwas. Der Klangcharakter der Welt (Schläft ein Lied in allen Dingen) ist nicht eine unverbindliche Metapher sondern korrespondiert mit unserer Fähigkeit zu hören. Nachfolgend wird deshalb vorgeschlagen, Hören als Anliegen des Sachunterrichts zu begreifen und im Rahmen einer ästhetischen Elementarerziehung zu thematisieren. Einige Unterrichtsbeispiele illustrieren, welchen Ertrag eine solche Sicht hat. Dabei soll auch deutlich werden, daß Hörerziehung kein Additivum sein kann, sondern wichtiges Glied schulischer Kommunikationsförderung. (DIPF/Orig.)

Produção e utilização de material didático sobre fisiologia da audição e neurofisiologia

The teaching of hearing physiology requires an knowledge integration of Human Anatomy, Biophysics, more precisely Bioacoustics and Bioelectrogenesis, as well as Neurophysiology. Students present difficulty to build knowledge about functional mechanisms of sound conduction and sensory transduction, especially if the elements are not visible forms, as the middle and inner ear structures. To make the teaching about hearing physiology and sensory perception easier, was produced a set of didactical materials about the subject. At first, a resin model that faithfully describes the anatomical relationship of the ossicles with the tympanic membrane was developed. Subsequently, a second model that, besides illustrates the mechanism of acoustic impedance overcoming, also reveals how acoustic sensorial transduction occurs in inner ear, was designed and produced. In the third didactical model, are visualized, through students interaction, areas of the cerebral cortex that interpret the different sensory modalities. In addition, were created three educational videos about hearing problems and a site on Human Hearing Physiology, available on Institute of Biosciences website. The results of this course conclusion monograph are presented in the form of articles that were submitted to Journal Physics in the School and the Journal of the Nucleus of Teaching

Auditory sensory memory and working memory processes in children with normal hearing and cochlear implants.

There can be wide variation in the level of oral/aural language ability that prelingually hearing-impaired children develop after cochlear implantation. Automatic perceptual processing mechanisms have come under increasing scrutiny in attempts to explain this variation. Using mismatch negativity methods, this study explored associations between auditory sensory memory mechanisms and verbal working memory function in children with cochlear implants and a group of hearing controls of similar age. Whilst clear relationships were observed in the hearing children between mismatch activation and working memory measures, this association appeared to be disrupted in the implant children. These findings would fit with the proposal that early auditory deprivation and a degraded auditory signal can cause changes in the processes underpinning the development of oral/aural language skills in prelingually hearing-impaired children with cochlear implants and thus alter their developmental trajectory

Hearing impairment affects older people’s ability to drive in the presence of distracters

OBJECTIVES: To investigate the effects of hearing impairment and distractibility on older people's driving ability, assessed under real-world conditions. DESIGN: Experimental cross-sectional study. SETTING: University laboratory setting and an on-road driving test. PARTICIPANTS: One hundred seven community-living adults aged 62 to 88. Fifty-five percent had normal hearing, 26% had a mild hearing impairment, and 19% had a moderate or greater impairment. ---------- MEASUREMENTS: Hearing was assessed using objective impairment measures (pure-tone audiometry, speech perception testing) and a self-report measure (Hearing Handicap Inventory for the Elderly). Driving was assessed on a closed road circuit under three conditions: no distracters, auditory distracters, and visual distracters. RESULTS: There was a significant interaction between hearing impairment and distracters, such that people with moderate to severe hearing impairment had significantly poorer driving performance in the presence of distracters than those with normal or mild hearing impairment. CONCLUSION: Older adults with poor hearing have greater difficulty with driving in the presence of distracters than older adults with good hearing.

Binang gurri: turning a deaf ear to indigenous hearing loss

Objective: This paper asks whether Indigenous health policies might be improved if governments listened to Indigenous voices, both Australian and those who drafted the Declaration on the Rights of Indigenous Peoples, 2007. Methods: A fundamental tenet of the Declaration, which Australia endorsed in 2009, is respect for Indigenous knowledge and voice. The author analyses legal, cultural and historical sources for evidence of this respect. The metaphorical and empirical framework of the analysis is the epidemic of otitis media among Indigenous children. Results: A survey of Indigenous advice about health clearly demonstrates that access to their land and respect for the diversity of Indigenous cultures should inform health policies. Despite, however, claiming to consult Indigenous peoples, policy-makers have not been listening. In many Indigenous languages not listening, or ‘bad ears’, has connotations of disrespect. Conclusions: By turning a deaf ear to Indigenous knowledge governments are undermining any respect Indigenous peoples may have for them and their policies. A new approach is needed. Implications: The Declaration on the Rights of Indigenous Peoples can provide federal, state and territory governments with benchmarks against which health policy can be developed and implemented. Authentic consultation could restore Indigenous confidence in government policies.

Acoustic hazard detection for pedestrians with obscured hearing

Pedestrians’ use of mp3 players or mobile phones can pose the risk of being hit by motor vehicles. We present an approach for detecting a crash risk level using the computing power and the microphone of mobile devices that can be used to alert the user in advance of an approaching vehicle so as to avoid a crash. A single feature extractor classifier is not usually able to deal with the diversity of risky acoustic scenarios. In this paper, we address the problem of detection of vehicles approaching a pedestrian by a novel, simple, non resource intensive acoustic method. The method uses a set of existing statistical tools to mine signal features. Audio features are adaptively thresholded for relevance and classified with a three component heuristic. The resulting Acoustic Hazard Detection (AHD) system has a very low false positive detection rate. The results of this study could help mobile device manufacturers to embed the presented features into future potable devices and contribute to road safety.

Civil applications in the Magistrates Court are often set down for hearing by a judicial registrar, but there is now some uncertainty on the limitation of this practice

The decision of the District Court of Queensland in Mark Treherne & Associates -v- Murray David Hopkins [2010] QDC 36 will have particular relevance for early career lawyers. This decision raises questions about the limits of the jurisdiction of judicial registrars in the Magistrates Court.

Hearing voice and silence during stressful economic times

Purpose - It is ironic that in stressful economic times, when new ideas and positive behaviors could be most valuable, employees may not speak up, leading to reduced employee participation, less organizational learning, less innovation and less receptiveness to change. The supervisor is the organization’s first line of defense against a culture of silence and towards a culture of openness. This research asks what helps supervisors to hear prosocial voice and notice defensive silence. Design/methodology/approach - We conducted a cross-sectional field study of 142 supervisors. Findings - Our results indicate that prosocial voice is increased by supervisor tension and trust in employees, while defensive silence is increased by supervisor tension but reduced by unionization of employees and trust in employees. This indicates that, as hypothesized by others, voice and silence are orthogonal and not opposites of the same construct. Research limitations/implications - The data is measured at one point in time, and further longitudinal study would be helpful to further understand the phenomena. Practical implications - This research highlights the potential for supervisors in stressful situations to selectively hear voice and silence from employees. Originality/value - This study adds to our knowledge of prosocial voice and defensive silence by testing supervisors’ perceptions of these constructs during difficult times. It provides valuable empirical insights to a literature dominated by conceptual non-empirical papers. Limited research on silence might reflect how difficult it is to study such an ambiguous and passive construct as silence (often simply viewed as a lack of speech). also contribute to trust literature by identifying its role in increasing supervisor’s perceptions of prosocial voice and reducing perceptions of defensive silence.

"Listening, hearing and drawing things together to work on solutions" : NAPCAN Play a Part, Queensland, 2010-2013, Evaluation-Research Report

Responding to the idea of child friendly communities, Play a Part is an innovative program advancing preventative strategies for children and young people to minimise exposure to abuse and neglect. The program was developed ensuing an increase in notifications of suspected child abuse and neglect in 2007. Now completing the second phase, the program is a community engagement strategy that aims to prevent child abuse. Play a Part is described as “a whole of community approach to creating child friendly communities” (NAPCAN, 2012). The Play a Part program was piloted between 2007 and 2010 in five southeast Queensland communities, and is currently operating in parts of Logan City region and the Redlands region. To assess the merit of the second phase of the program the Children and Youth Research Centre at Queensland University of Technology was contracted to undertake an evaluation-research at the beginning of 2013.
