Folscher, Lindy-Lee January 2013 (has links)
A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Medicine in Emergency Medicine. Johannesburg, 2012 / Introduction: Healthcare professionals working in the Emergency Medicine field are often required to function in difficult environments. Noise is one environmental factor that may adversely affect their performance. Objectives: To firstly determine if there is any difference in cognitive task performance required for clinical decision-making of healthcare professionals in a quiet compared to a noisy environment and secondly, to assess the subjective experience of participants with regards to performance in a noisy environment. Design: Prospective cross-over study. Setting: Three Academic Hospitals in Johannesburg. Participants: Forty one doctors exposed to emergency management of patients. Methods: A 30 minute examination consisting of six matched and pre-validated questions was conducted. Half of the questions were completed with exposure to ambient noise (range 40-45dB(A)) and the other half with exposure to pre-recorded background Emergency Department noise at 80-85dB(A). The questions were completed in alternating quiet and noise. Each question was scored out of 10 and the time taken to complete each question was recorded. Main Results: Overall mean test scores in quiet and noise were 18.7/30 and 19.4/30 (p=0.36) respectively, with overall time for test completion of 836s in quiet and 797s (p=0.005) in noise. While there was no statistically significant difference in task performance, 65% of the doctors found the noise distracting with 88% experiencing varying degrees of stress. Conclusions: This study showed no difference in cognitive performance in a quiet compared to a noisy environment. Deterioration in functionality might be seen with higher levels of noise and/or longer exposure.

Objective: Measuring sound levels and identifying auditory and non-auditory complaints on pop-rock musicians groups. Method: 34 male pop-rock musicians, ages between 26 and 60 years old were evaluated. The subjects answered a questionnaire composed of health history, complaints related to hearing and information about music exposure. The noise dosimeter was applied on the musicians during a band concert on a nightclub in São Paulo. It was used a dosimeter type 1, properly calibrated, in which the microphone was positioned behind the musician s ear, 5 minutes before the beginning of the presentation. Results: The prevalence of auditory complaints, loud sound intolerance and the felling of occluded ears was 20,6%. From all, 50% of the sample reported the thought of being exposure to that sound can damage their hearing. The majority (27, 79,4%) of the musicians work in this area for further than 10 years. The highest sound level obtained on Lmax variation medium maximum levels, Lavg - average levels and Lmin - medium minimum levels in dB (A) were of 129,6; 119,1 and 94,5 (respectively). The values were further above the maximum level daily allowed, according to the occupational legislation. Conclusions: Dosimeter can be useful on levels investigation. Although, measures for musicians protection must be immediately taken, so that it can avoid deleterious effects on this population health / Introdução: Os músicos representam uma categoria profissional sob risco de problemas auditivos e queixas de saúde, em decorrência da exposição à música eletronicamente amplificada. Objetivo: Medir os níveis sonoros e identificar queixas auditivas e não auditivas em músicos de bandas de pop-rock. Método: Foram avaliados 34 músicos de pop-rock, do sexo masculino, com idades entre 26 e 60 anos. Os sujeitos responderam um questionário com dados sobre histórico de saúde, queixas relacionadas à audição e informações sobre exposição à música. Foi realizada a dosimetria de ruído no músico durante uma apresentação da banda em uma casa noturna de São Paulo. Para tanto foi utilizado um dosímetro do tipo 1, devidamente calibrado, cujo microfone foi posicionado próximo à orelha do músico, cinco minutos antes do início da apresentação. Resultados: A prevalência das queixas auditivas intolerância a som intenso e sente os ouvidos tampados foi de 20,6%. Do total, 50% da amostra relataram achar que o som ao qual está exposto afeta sua saúde. A maioria (27, 79,4%) dos músicos trabalha na profissão há mais de 10 anos. Os maiores níveis sonoros obtidos nas variáveis Lmax nível médio máximo, Lavg nível médio e Lmin nível médio mínimo em dB (A) foram de 129,6; 119,1 e 94,5 (respectivamente). E os menores foram de 105,9; 94,5 e 62,2 (respectivamente). Os valores estavam muito acima dos níveis máximos diários permitidos, segundo a Legislação Trabalhista. Conclusões: A dosimetria pode ser útil na investigação dos níveis. Entretanto, medidas de proteção aos músicos devem ser imediatamente adotadas com o objetivo de evitar os efeitos deletérios à saúde dessa população

Proposta de programa de prevenção de perdas auditivas para músicos

Munhoz, Graziella Simeão 16 February 2016 (has links)
INTRODUÇÃO: A audição é um dos sentidos mais importantes para o ser humano, e seu funcionamento está interligado à sua produtividade, o que não é diferente aos músicos, já que ela é de suma importância para a qualidade de seu trabalho e permanência na carreira. O desenvolvimento de um programa de prevenção de perdas auditivas tem por objetivo modificar o comportamento dos músicos em relação à sua audição, uma vez que, constantemente, estão expostos a níveis de pressão sonora elevados e ao surgimento de lesões irreversíveis. Contudo, se medidas preventivas não forem realizadas corretamente, as exposições dos músicos frente à intensidade sonora elevada podem trazer prejuízos à saúde e alguns destes, irreversíveis como, a Perda Auditiva Induzida por Níveis de Pressão Sonora Elevados (PAINPSE) ou Perda Auditiva Induzida por Música (PAIM). OBJETIVO GERAL: submeter os músicos ao programa de prevenção de perdas auditivas (PPPA) e verificar sua eficácia. MATERIAL E MÉTODOS: Participaram componentes de quatro bandas musicais, correspondendo a um total de 16 participantes. Esses membros foram submetidos ao Programa de Prevenção de Perdas Auditivas (PPPA) que engloba as seguintes etapas: (1) medição do nível de pressão sonora no ensaio e show; (2) entrevista específica, Audiometria Tonal Liminar e de Altas Frequências, Logoaudiometria, Imitanciometria e Emissões Otoacústicas por estímulo Transientes e Produto de Distorção; (3) orientação sobre a utilização do Equipamento de Proteção Individual (EPI); e (4) a realização de medidas educativas por meio de workshops. RESULTADOS: O Nível de Pressão Sonora (NPS) durante os ensaios e apresentações/shows, encontram-se elevados, sintomas não auditivos estão presentes em 68, 75% da população total da amostra, presença de zumbido após o show em 100% da amostra; maiores dificuldades de compreensão de fala no ruído nos músicos que tocam baixo (75%). Ao traçar o perfil audiológico do músico foram encontrados: maiores médias dos limiares audiológicos por frequência das bandas estudadas em 500Hz e 3KHz (B1), 3KHz e 4KHz (B2), 3KHz, 4KHz e 6KHz (B3) e em 3KHz (B4); as maiores médias dos limiares audiológicos por frequência dos instrumentos estudados foram em 3KHz, 4KHz e 6KHz (voz), 3KHz e 4KHz (guitarra), 3KHz, 4KHz e 6KHz (baixo) e 3KHz, 4KHz (bateria); presença de entalhe nas frequências de 2KHz, 4KHz, 6KHz e 8KHz na audiometria tonal liminar; já na audiometria de altas frequências em todas as frequências apareceram ao menos um caso, reflexos ausentes em 4KHz (ipsilateral e contralateral); ausência de resposta em 4KHz para todos os baixistas bilateralmente (100%) quando pesquisado EOE por estímulo transiente e na produto de distorção foram encontradas ausência de respostas em 50% da amostra na frequência de 6KHz, sendo assim pesquisada a curva de crescimento (dp growth rate) aparecendo resposta em 75dB em quase 100% dos casos em que houve necessidade de sua realização. Quanto aos achados obtidos da avaliação realizada pelos participantes (músicos) referente ao website, os resultados mostraram que o mesmo atende às necessidades propostas, ou seja, a promoção da saúde auditiva em músicos. CONCLUSÃO: Existe a necessidade de serem tomadas medidas preventivas e a inserção dos músicos em um Programa de Prevenção de Perdas Auditivas (PPPA) a fim de proporcioná-los maiores condições de qualidade de vida e em seu trabalho, já que necessitam da sua audição para desempenhar com eficácia suas atividades e se manter no mercado de trabalho atuando como músico. / INTRODUCTION: Hearing is one of the most important senses for the human being, and its operation is interconnected to its productivity, which is no different to the musicians, since it is of the utmost importance for the quality of their work The development of a hearing loss prevention program, aims to modify the musicians behavior in relation to their hearing, once, constantly, are exposed to high sound pressure levels and the emergence of permanent injury. However, if preventives measures are not performed correctly, the exposures of the musicians facing the high sound intensity can bring losses to health and some of these, irreversible such as, Hearing Loss Induced by High Sound Pressure Levels (HLIHSPL) or Music-induced hearing loss (MIHL) - Noise-Induced Hearing Loss (NIHL). GENERAL OBJECTIVE: submit the musicians to the Hearing Loss Prevention Program (HLPP) and verify its effectiveness. MATERIAL AND METHODS: participated components from four musical bands, corresponding to a total of 16 participants. These members were submitted to the Hearing Loss Prevention Program (PPPA) that include the following steps: (1) measurement of the sound pressure level at the rehearsal and concert; (2) specific interview, Pure Tone Audiometry and High Frequencies, Logoaudiometry, Imitanciometry and Distortion Product Evoked Otoacoustic Emissions (DPEOE); (3) guidance on the use of Personal Protective Equipment (PPE); and (4) the achievement of educational measures through workshops. RESULTS: The Sound Pressure Level (SPL) during the rehearsals and performances/shows are elevated, symptoms not auditory are presents in 68,75% of the total sample population, presence of tinnitus after the show in 100% of the sample; major difficulties of speech comprehension in the noise of the musicians who playing bass (75%). When plotting the audiological profile of the musician were found: highest averages of audiological thresholds by frequency from the studied bands in 500Hz and 3KHz (B1), 3KHz and 4KHz (B2), 3KHz, 4KHz and 6KHz (B3) and in 3KHz (B4); the major averages of audiological frequency thresholds of the studied instruments were in 3KHz, 4KHz and 6KHz (voice), 3KHz and 4KHz (electric guitar), 3KHz, 4KHz and 6KHz (bass) and 3KHz, 4KHz (drums); presence of notch in the frequencies of 2KHz, 4KHz, 6KHz and 8 kHz in the pure tone audiometry; but in the high audiometry frequencies, in all frequencies appeared at least one case, missing reflexes in 4KHz (ipsilateral and contralateral); missing reply in 4KHz for all bassists bilaterally (100%) when researched EOE by transient stimulus and in the distortion product were found missing responses in 50% of the frequency sample of 6KHz, so researched the growth curve (dp growth rate) showing response in 75dB at almost 100% of cases which there was need for its achievement. CONCLUSION: there is a need to take preventive measures and the insertion of the musicians in the Hearing Loss Prevention Program (HLPP) in order to provide them greater conditions of quality of life and in their work, since they need their hearing to play effectively their activities and stay in the labor market working as a musician.
