This book was released on 2012 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective learning occurs in auditory environments. Background noise is inherent to classrooms with recommended levels 15 decibels softer than instruction, which is rarely achieved. Learning is diminished by interference to the auditory reception of information, especially for students who are hard of hearing other diagnoses. Sound-field amplification (SFA) addresses the need for improving the noise to speech ratio while decreasing the distance between the sound source and the student's ear. The use of SFA amplifies the teacher's voice above ambient noise. This is accomplished by the placement of a receiver/amplification system in the classroom along with the teacher's use of a microphone and FM transmission device. Examination of previous research demonstrates the effectiveness of sound-field technology for elementary school children, establishing a rationale for using sound-field amplification with students who are of early childhood age. The purpose of this single subject study is to examine the effects of SFA used for children with hearing loss and additional diagnosed conditions enrolled in preschool, first, and second grade classes. The four focus students were matched with peers for further control, and studied for both displaying attending behaviors and rate of compliance following routine directions in order to demonstrate comprehension of spoken material. All participants demonstrated improvement in their attending behavior and compliance to directions. Focus students with hearing loss produced stronger results than their general education peers to the activation of the sound-field system. Teachers indicated that the sound-field system was beneficial to the focus students. All teachers reported they would use it again.

Download or read book The Influence of Improved Acoustics on English First Additional Language Teaching and Learning in the Foundation Phase written by Mpho Otlametse Marumo and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: English First Additional language is introduced to the non-speakers of the language in Grade 1. This is in line with the Curriculum Assessment Policy Statement, which requires English to be introduced to Grade 1 learners irrespective of their home language or their language background (Department of Basic Education, 2012). To the majority of learners in South Africa, English is a second or a third language. Learning a new language poses numerous challenges, such as inability to decipher the sound system of the language. Moreover, primary school classrooms are known for being action filled and accommodative of what is known as "productive noise", which makes it difficult for Foundation Phase teachers to be audible to all learners in the classrooms. Options that are commonly used to reduce noise are hanging curtains and fitting tennis balls on the legs of chairs. This study focused on the use of a dynamic sound field amplification system as one way to improve acoustics in the classroom. The purpose of this study was to document the teachersaÌ22́Ơ4́Ø experiences when using dynamic sound field amplification system. Although this study was not an intervention, the concept evaluation was used to understand teachersaÌ22́Ơ4́Ø experiences and challenges as regards the background noise in their classrooms. This study was conducted in three Grade 1 mainstream classrooms where English First Additional Language is used for teaching and learning in the North West Province, South Africa. The classroom observations afforded me the opportunity to see how the learners reacted in the improved acoustic classroom. Lastly, the discussions with the teachers enabled me to hear how they feel about the use of the dynamic sound field amplified system. Components of the Programme Theory Evaluation with its relevance on change underpinned this study. For the purpose of this study I focused on the five steps or levels of theory of change i.e. inputs, activities, outputs, outcomes and impact (Evaluation Exchange, 2006). The practical application of the Programme Theory Evaluation guided the documentation of the teachersaÌ22́Ơ4́Ø experiences. The use of dynamic sound field amplification system helped with the early identification of learning barriers and interventions in the three schools. This lessened the number of learners who were wrongly referred to special schools because of poor performance. TeachersaÌ22́Ơ4́Ø health, high rates of absenteeism and voice fatigue were reduced, and classroom management was facilitated. The study found that the participants were not aware of the importance of acoustics in the classroom before dynamic sound field amplification system was introduced. They had to speak at the top of their voices and often repeated themselves for their learners to hear and understand. The dynamic sound field amplification system changed all that, the teachersaÌ22́Ơ4́Øvoices were amplified and that improved the acoustics in the three classrooms. The dynamic sound field amplification system is effective in the overcrowded classrooms where the background noise is normally high; it operates by amplifying the teacheraÌ22́Ơ4́Øs voice relative to the background noise. The teacheraÌ22́Ơ4́Øs amplified voice remains constant all the time and equally audible to all learners in the classroom at all the times. (DiSarno, Schowalter & Grass, 2002). The recommendations of this study are to share the information gathered from the three schools and the two district officials with the senior management of the North West Department of Education. They will be in the position to study the outcomes and assist schools accordingly by deciding if they see the importance of treating acoustics in the classrooms.

Download or read book Occupational Voice written by Philippe H. Dejonckere and published by Kugler Publications. This book was released on 2001 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction The concept of occupational voice disorders Philippe H. Dejonckere "People using their voice professionally are at risk for occupational voice diseases, and require specific prevention and treatment" was the topic focused on by the third Pan European Voice Conference, organized in August 1999 at Utrecht University. The present book includes the main tutorial lectures, with reviews of the most relevant research data and opinions regarding this specific area of concern. Occupational voice users include not only singers and actors, but also teachers, politicians, lawyers, clergymen, telephone operators, etc.(1). The pathogenesis of voice disorders in such patients can be primarily related to their occupation, and thus, after adequate differential diagnosis, these need to be recognized as true occupational diseases, in the same way as, for example, occupational hearing loss (2). A surfeit of information is available on the potential damage from exposure to excessive noise levels(3,4). Noise-induced hearing loss is generally recognized as a typical occupational disease. The relationship between dose and effect is clear, as is documented in publications by the International Organization of Standardization (ISO) (5). The dose combines intensity and duration, and therefore, the concept of dosimetry is of major importance. Also of importance is the definition of the safe limits for exposure to noise. However, factors regarding individual susceptibility to noise and the reversibility of early effects also have to be considered, as well as possible preventive indices of noise-induced hearing loss (6). In some - but not all - respects, noise-induced hearing loss may be considered as a useful model for occupational voice disorders. Epidemiology Titze (7) compared the percentage of the US working population and of the voice-clinic load for different occupation categories: for example, telephone marketers constitute only 0.78% of the total workforce, but 2.3% of the clinic load; teachers represent 4.2% of the US workforce and 20% of the voice-clinic load. Studies based on questionnaires have suggested that teachers and aerobic instructors are at high risk for disabilities from voice disorders, and that these health problems may have significant work-related and economic effects (8,9). For example, Russel et al.(10) investigated the prevalence of self-reported voice problems in teachers: 16% of teachers reported voice problems on the day of the survey, 20% during the current teaching year, and 19% at some time during their career. Roughly speaking, we can conclude from the several studies published during the 1990s that about 20% of teachers experience voice disorders (11). Voice dosimetry Objective measurement of vocal use and vocal load is necessary for the identification of activities and working conditions that are at risk. Voice dosimeters can provide information on the total vocalization time and sound pressure level over a whole working day, in a real life situation (12-14). Just as noise dosimeters define acceptable levels of noise exposure, voice dosimeters help to define the average acceptable limits for vocal load. Hyperphonation Repeated mechanical vibrations transmitted to the body tissues by engines or machines are known to be able of eliciting - in certain conditions - specific kinds of pathology, which are also considered to be occupational diseases (15,16). The vibration may involve the whole body (e.g., in a vehicle) or mainly the hand, wrist, elbow, or shoulder (hand-held power tools). There are standards in the field of occupational health that stipulate the acceptable limits for tissue acceleration values, depending on the frequency (17). Titze's calculations suggest that the risk of damage from tissue vibration is exceeded by occupational vocalists, such as telephone marketers and teachers (18). In the last few years, much new and important information has materialized on the dangers of 'hyperphonation', i.e., loud and prolonged phonation beyond the physiological range. Laboratory experiments on canine larynges, hyper-phonated in vivo under anesthesia, demonstrated obvious damage to vocal fold epithelia (19). The basement membrane shows early lesions and seems to be particularly sensitive (20). A clinical study by Mann et al.(21) in drill sergeants, demonstrated significant increases in vocal fold edema, erythema and edge irregularity, and decreases in vocal fold mucosal wave and amplitude of excursion, following a five-day training period Voice fatigue, relief and recovery According to Titze (18) , two different aspects must be considered: Muscle fatigue: the muscle chemistry needs to be reset for the following contractions. Epithelial cells may die and be shed, due to repeated traumata. New cells have to develop underneath. Collagen and elastin fibers may have separated from the structural matrix of the lamina propria, and have to be removed and replaced by the fibroblasts. Detached protein debris will be removed and re-used by the fibroblasts to make new protein fibers that will support the connective tissue structure. Therefore, minor destruction and repair is continuous. Can the regenerative processes keep up with the destructive process, and what are the physiological time constants in these processes? When there is damage to the joints, ligaments, tendons, or other connective tissue, the recovery time will be proportional to the amount of localized tissue injury that has occurred. If muscle fatigue is the only complaint, the recovery period required will probably be shorter. Hypothetical curves for tissue injury and the recovery period for human phonation have been suggested by Titze (18). Nevertheless, vocal fatigue is still difficult to identify in practical and clinical situations, and Buekers has questioned the clinical relevance of voice endurance tests (13,14). Environmental factors The relative humidity of the air affects vocal function: the most common subjective complaints of teachers with regard to their working environment are the dryness and dustiness of the air. Professional singers note that singing is more difficult in a dry environment: dry air puts an increased strain on the phonatory apparatus and raises the demands on its efficacious and appropriate use (22). The human voice is very sensitive to decreases in the relative humidity of inhaled air because, in experimental conditions, even after short provocation, a significant increase in perturbation measures has been found (23). Noise is also a very common and relatively well-known risk factor in the working environment of professional voice users. It has been observed that the sound level of the speaking voice significantly increases in ambient noise levels starting from 40 dB (A) (about 3 dB for each 10 dB increase in ambient noise), due to the Lombard effect (24,25). In kindergartens, for example, noise levels have been found to vary between 75 and 80 dB (A) (26,27). Effects of stress Mendoza and Carballo investigated the effects of experimentally induced stress on voice characteristics (28). In conditions of stress, induced by means of a stressful environment and cognitive workload tasks, they observed: 1. an increase in F o with respect to baseline; 2. a decrease in pitch perturbation quotient and in amplitude perturbation quotient; 3. a lower presence of turbulent noise in the spectral zone in which the existence of harmonic components is not expected (2800-5800 Hz), with respect to harmonic energy in the 70-4500 Hz range; 4. an increase in harmonic energy in the 1600-4500 Hz range with respect to harmonic energy in the 70-1600 Hz range. The increase in F o seems to be considered a universal indicator of stress and of cognitive workload, as is the lowering of F o perturbation. The response to a stressful stimulus demands a high level of activation, which in turn produces elevated ergotropic arousal that would cause an increase in the tension of the vocal muscles, producing a higher and more tense voice. Mattiske et al. (29) report that teachers seem to experience a significant degree of stress during their work (30) , and there is some research evidence that anxiety and stress are associated with the development of voice problems (31). Marks (32) compares teachers' voices with those of nurses, and finds that psychological stress is reported more frequently by teachers. There are indications that stress, psychological tension, personality, and other psychological factors, may play an important role in voicing problems among teachers (30,33,34). Vocal fold lesions Phonotrauma may result in typical vocal fold lesions, to be interpreted as a direct consequence of mechanical stress and/or as tissue reaction to that stress. Vocal fold nodules and polyps are classical examples (35,36) , but also contact ulcerations/ granulomas of the vocal processes (35,36,37) , if not induced by acid re-flux. Vocal fold hemorrhage is generally consecutive to acute phonotrauma (35). Depending on reversibility and context, microsurgery may become indicated as an important element of the treatment (38,39). Care and cure Patients with occupational voice disorders should benefit from specific medical and paramedical treatments, as well as from technical aids, with respect to their particular pathogenesis. There are major economical aspects at stake, and occupational rehabilitation plays an important role. In a few cases, compensation and professional re-orientation is necessary. Outcomes of the various possible treatment strategies have still to be investigated. However, prevention is still essential. There are indications that vocal hygiene education programs could improve the voice by reducing vocal abuse in daily life and by practising specific strategies to maintain classroom order and to reduce the use of the voice during teaching (40). Further research is needed to demonstrate the usefulness of prevention strategies on the incidence of actual voice disorders.

Available in PDF, EPUB and Kindle. Book excerpt: A well-functioning voice is part of the professional skills needed in many occupations. Although voice is an important communication tool, it is more than that: it is something which reflects human identity. The need for speech and voice is growing in spite of increasing technology applications; even instruments and technical equipment are guided by voice. The number of people having voice problems is increasing, which implies that voice does not always function according to the speakers’ needs. Voice ergonomics has been developed for improving voice health and care. This book offers background knowledge and concrete guidelines on how to improve communication environments and practices for decreasing voice loading.
