    Translation, adaptation, and cross-cultural validation into Brazilian portuguese of the hearing protection assessment questionnaire (HPA)
    (Sociedade Brasileira de Fonoaudiologia, 2023-05-01) Bramati L; Gonçalves CGDO; Marques JM; Reddy R; Welch D; Lacerda ABDM
    PURPOSE: The aim of the present study is to translate, adapt, and cross-culturally validate the Brazilian Portuguese version of the questionnaire Hearing Protection Assessment Questionnaire (HPA). METHODS: The original instrument, developed in English, seeks to assess barriers and supports related to the use of hearing protection devices (HPD), as well as workers' knowledge, habits and attitudes towards occupational noise. The translation, adaptation, and cross-cultural validation of the questionnaire consisted of five steps: Translation of the questionnaire from English to Portuguese; 2) Reverse translation from Portuguese to English; 3) Analysis of the instrument by three experts in the field; 4) Pre-test of the questionnaire with ten workers; 5) Application of the instrument to 509 workers in a meatpacking industry after the pre-employment medical exam. RESULTS: The results indicate the construction and content validity of the Brazilian Portuguese version for use with a working population and its internal consistency. CONCLUSION: This study resulted in the translation, cultural adaptation, and validation of the Hearing Protection Assessment Questionnaire (HPA), in order to be used to assess the use of individual hearing protection in the occupational field, called Hearing Protection Assessment Questionnaire (HPA).

    Baseline audiological profiling of South African females with cervical cancer: an important attribute for assessing cisplatin-associated ototoxicity
    (BioMed Central Ltd, 2021) Paken J; Govender CD; Pillay M; Ayele BT; Sewram V
    Background Cisplatin is a popular antineoplastic agent used to treat cervical cancer in women from low and middle-income countries. Cisplatin treatment is associated with ototoxicity, often resulting in hearing loss. In light of this, it is crucial to conduct baseline audiological assessments prior to treatment initiation in order to evaluate the extent of cisplatin-associated-ototoxicity. Additionally, the identification of inherent risk factors and hearing patterns in specific patient cohorts is needed, especially in South Africa, a middle-income country characterized by the quadruple burden of disease (Human Immunodeficiency Virus (HIV), Tuberculosis (TB), Diabetes and Hypertension). Methods This study aimed to describe a profile of risk factors and hearing in a cohort of females with cervical cancer before cisplatin treatment commenced. A descriptive study design that included 82 cervical cancer patients, who underwent audiological evaluation prescribed for ototoxicity monitoring was conducted. Results All participants (n = 82) presented with risk factors (diabetes, hypertension, HIV, and antiretroviral therapy) for cisplatin ototoxicity and/or pre-existing sensorineural hearing loss. High-frequency tinnitus was the most common otological symptom experienced by 25 (31%) participants. Fifty-nine (72%) participants presented with normal hearing, twenty-two (27%) with a sensorineural hearing loss, and 36% were diagnosed with mild hearing loss. Abnormal Distortion Product Otoacoustic Emissions (DPOAE) findings were obtained bilaterally in two participants (2.4%), in the right ear only of another two (2.4%) participants and the left ear of three participants (3.7%). Most participants (94%) had excellent word recognition scores, demonstrating an excellent ability to recognize words within normal conversational levels under optimal listening conditions. Age was significantly associated with hearing loss at all thresholds. Among the co-morbidities, an HIV positive status significantly triggered hearing loss, especially at higher frequencies. Conclusion This study demonstrated that South African females with cervical cancer present with various co-morbidities, which may predispose them to develop cisplatin-associated -ototoxic hearing loss. Identification of these co-morbidities and hearing loss is essential for the accurate monitoring of cisplatin toxicities. Appropriate management of these patients is pivotal to reduce the adverse effects that hearing impairment can have on an individual’s quality of life and to facilitate informed decision-making regarding the commencement of cisplatin chemotherapy.

    Noise in early childhood education centres: the effects on the children and their teachers : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Massey University, Wellington, New Zealand
    (Massey University, 2008) McLaren, Stuart Joseph
    Although the effects of noise on children’s learning in school classrooms is well documented, there is very little on the effects of noise on preschool children. There are strict legal requirements for the daily noise exposure an adult worker can received in the workplace but nothing to control the noise children can receive in school and early education. There is also little or no data on how sound affects a child, compared to an adult. The early years of life are critical for the development of speech, hearing and auditory processes, as well as being the most vulnerable time for middle ear infections. This work sets out to determine the typical noise levels in early childhood centres and the effects on a range of children and their teachers. Reverberation times in most centres were found to well exceed the 0.6 seconds prescribed by the Australasian standard for schools and learning spaces. Very high levels of noise were recorded in a number of centres with a significant number of children and staff members, exceeding the maximum daily sound exposure of 100% permitted for workers in industry. A range of special needs children were identified as being particularly at-risk to noise, with the most adverse outcomes reported for those experiencing sensory integration disorder. Yet, even though high levels of noise were recorded, the majority of respondents in a survey of teachers rated the lack of sufficient space for the number of children present as the main issue, and inclement weather as the greatest environmental condition contributing to noise (by confining children indoors, especially over long periods of time). Hearing tests on the children were not permitted under the strict human ethics criteria to which this study had to conform, but simple hearing tests on a small group of teachers, revealed that hearing loss could be a serious occupational health issue. The legal issues of noise control and management in early childhood education have been addressed in this thesis, current legal frameworks reviewed, and recommendations presented for future consideration.

    This is a journey into sound/bring the noise : a thesis presented in partial fulfilment of the requirements for the degree of Master of Fine Arts at Massey University, Wellington, New Zealand
    (Massey University, 2009) Cairns, Gregory John
    The aim of this thesis is to survey the discussions around the position of sound art within the broader arts, and to explore strategies and research areas within fine art and my own practice, so as to identify new areas of enquiry and develop my work within this field. I investigate the phenomenology of vision and hearing and contrast the different ways these two senses operate as primary sources of perception. I analyse the privileging of sight and the dominance of the visual in art institutions. Ideas of the literal and model subject within installation art are explored and the convergence of these subjectivities is overlaid with this phenomenological research, in order to develop a direction within installation art. The lack of authoritative sources in this field, beyond the few relevant texts, has meant that my research has employed respected new media and the Internet as a second tier of sources. I also analyse my own practice as an example of how sound art activates extramusical ideas. My research concludes that sound art has much to reveal to the broader arts community about perception and the creation of meaning, and also that there are many prospective avenues of enquiry within fine arts for the inclusion and analysis of audio based work. Keywords: sound art; phenomenology; hearing; privileging of sight; subjectivities; extramusical; perception.
