PoluiÃÃo sonora na escola:perceber, apreciar, conscientizar e reciclar sons para musicalizar / Noise pollution in school: realize, appreciate, awareness and recycle sounds to musicalizar

Deise da Costa Crispim 15 July 2016 (has links)
O presente trabalho, representado por uma Proposta PedagÃgica, toma como objeto de estudo a educaÃÃo musical, no que se refere especificamente à musicalizaÃÃo, tendo como ponto de partida a poluiÃÃo sonora. Para tanto, expÃe, reflete, relata e propÃe atividades relacionadas ao assunto, utilizando-o como recurso de percepÃÃo, apreciaÃÃo, conscientizaÃÃo e aprendizagem musical, por meio dos sons. Com isso, aborda questÃes relevantes acerca da paisagem sonora, trazendo educadores musicais, tais como Schafer, Swanwick e Fonterrada, que dialogam e refletem sobre o processo de ensino aprendizagem da mÃsica. Concomitantemente, esse estudo apresenta um relato de experiÃncia do ensino de mÃsica nas escolas municipais Professor Berilo Wanderley e EmÃlia Ramos, no municÃpio de Natal, Rio Grande do Norte, a partir da poluiÃÃo sonora, representada diferentemente em cada uma delas. As experiÃncias vivenciadas, bem como as atividades desenvolvidas nesta proposta pedagÃgica, foram obtidas por meio de um projeto de pesquisa, numa abordagem qualitativa, na qual se utilizou materiais como gravaÃÃes, filmagens, entrevistas de sondagem, atividades musicais teÃricas e prÃticas, dinÃmicas, dentre outros recursos pedagÃgicos, para construÃÃo e obtenÃÃo dos dados comprobatÃrios aqui descritos. / This work is represented by a pedagogical proposal and takes music education as object of study, as far as musicalization is concerned, and it also takes noise pollution as its starting point. For this reason, this work exposes, reflects, reports and proposes activities related to the subject, using it as a tool of perception, appreciation, awareness and music learning by means of sounds. It addresses relevant questions about the soundscape by bringing music educators, such as Schafer, Swanwick and Fonterrada, and by dialoguing and reflecting on the process of music teaching and learning. Concurrently, this work brings an account of music teaching in the following municipal schools: Professor BeriloWanderley and Professora Emilia Ramos, in Natal, Rio Grande do Norte. The starting point of this account was the noise pollution, which was represented differently in each municipal school. The experiences and activities developed in this pedagogical proposal were obtained by means of a research project, in a qualitative approach in which materials such as recordings, films, interviews, theoretical musical activities and practices, dynamics were broadly used, among other teaching resources designed to construct and obtain corroborative data described herein.

Stress and the sick building syndrome : biopsychosocial health-related variables affecting workers employed in urban places where live or discotheque musical entertainment is provided.

Shadwell, Anthony. January 1995 (has links)
This is the first time that multidisciplinary research has been conducted in South African music venues. The study investigated biopsychosocial health-related variables affecting workers in music venues giving special attention to sick building syndrome. Monitoring methodologies developed for this investigation can be applied in studies of a wide range of workplace environments. This study also resulted in the design of a questionnaire which provided interpretable data within statistical significance limits. The literature review fully describes the multidisciplinary nature of this research. Long established non-smoking offices were selected as controls. An environmental monitoring system was designed to record conditions whilst questionnaires on staff perceptions were personally administered. Psychosocial variables included job satisfaction, self-esteem, personal confidence and social interaction.Environmental comfort assessments included lighting, carbon dioxide, movement, temperature, relative humidity levels and air movement. Pollution impact monitoring involved noise, respirable aerosols, benzene, toluene, xylene, benzo(a)pyrene, total volatile and semi-volatile organic compounds. Comfort criteria were exceeded in all music venues which caused stress. Only 21,1% of respondents did not experience tiredness. Respiratory infection was higher in music venue staff than in office staff. Average age of staff in music venues was 25 years and 67,37% were smokers. Certain smokers were experiencing discomfort from tobacco smoke pollution. Tobacco smoke impact was demonstrated: mean benzene level for music venues was 12,9 u/m3 (maximum 42,44 u/m3) and in offices it was 0,606 u/m3 (maximum 1,24 u/m3). Multivariate models for sick building syndrome and allergies included tobacco smoke odour concern and the tobacco smoke indicators, xylene and toluene. Aerosol levels were 1,75 mg/m3 (maximum 45,98 mg/m3 ) in music venues compared to an office mean of 0,02 mg/m3 (maximum 0,58 mg/m3 ). Contributors were tobacco smoke and theatrical smoke. Burning eyes was the symptom causing most concern for 57,89% of respondents. Symptoms that affected 20% and more of the workers were itchy skin, throat irritation, coughing and difficulty in breathing. Tobacco smoke was considered the main stressor. Noise level mean for music venues was Neq 99,67 dB (A). Only 34,7% of the staff considered music noise a stressor, with 16,9% concerned about people noise. The percentage that considered their environment to be polluted was 81,06%, however, only 48,42% felt stressed. Virtually all univariate and multivariate associations between psychosocial and psychophysical variables suggest that satisfaction with psychosocial factors may have a positive influence on staff in places of entertainment. / Thesis (M.Med.Sc.)-University of Natal, 1995.

O direito ao meio ambiente equilibrado e a criação de espaços públicos para regrar a polução sonora veicular

Constante, Marcelo Segala 23 February 2018 (has links)
A poluição ambiental tem se mostrado cada vez mais presente na vida das pessoas, de diversas formas, desde as mais evidentes até as mais obscuras. A produção desenfreada de ruídos é uma das formas de poluição que afeta gravemente a qualidade de vida das pessoas. A poluição sonora é uma forma de poluição que causa um impacto de uma forma que poucos percebem. Primeiramente pelo fato de que seus danos não são perceptíveis, por não ser reconhecida pelos órgãos jurisdicionais como poluição ambiental, e por não receber a atenção necessária dos órgãos públicos que deveriam atuar na sua contenção. Uma das formas de poluição sonora que está mais presente na vida das pessoas, devido ao processo de evolução da tecnologia e também por causa do hiperconsumismo que se observa na atualidade, é a poluição sonora veicular, produzida através de equipamentos de som instalados em veículos automotores. Essa forma de propagação de ruídos é percebida de forma cada vez mais ampla no meio urbano, se mostrando um meio propagador de ruído muito presente da sociedade moderna. Como possui uma regulamentação que sai do campo do direito ambiental, não recebe o atendimento correto. além disso, o que observa-se são as leis municipais deixando de regular esse assunto tão importante, que acaba por afetar diretamente a qualidade de vida dos cidadãos. Os planos diretores das cidades regulam o parcelamento e formas de ocupação do solo, porém não dão atenção à necessidade de zonear as áreas de maior impacto por parte de poluição sonora e de fornecer locais aptos a receber certos tipos de atividades típicas e comuns da sociedade moderna, como a poluição sonora de equipamentos de som de veículos automotores, ensejando assim na produção de ruídos por estes equipamentos. Este trabalho discute os problemas atinentes à poluição sonora veicular, partindo do estudo da legislação sobre o assunto, abordando as decisões judiciais através de pesquisa quantitativa e qualitativa de jurisprudências do Tribunal de justiça do Rio Grande do Sul, e o porquê é tão presente na sociedade moderna. Através do método hipotético dedutivo e da pesquisa bibliográfica e documental, será analisado também quais as políticas adotadas no município de Caxias do Sul, algumas políticas adotadas em outros países, mostrando como que a cidade de Lisboa, em Portugal, tratou do assunto de maneira eficiente, e como o direito urbanístico poderia ser uma das formas de contenção deste tipo de poluição sonora que afeta a qualidade de vida da sociedade. / Submitted by cmquadros@ucs.br (cmquadros@ucs.br) on 2018-03-16T17:31:21Z No. of bitstreams: 1 Dissertacao Marcelo Segala Constante.pdf: 3173092 bytes, checksum: 3d74c040f0dbffcd73743faa4a08ba89 (MD5) / Made available in DSpace on 2018-03-16T17:31:21Z (GMT).

Rampant production of noise is one of the forms of pollution that seriously affects people's quality of life. Sound pollution is a form of pollution that causes an impact in a way that few realize.

One of the forms of noise pollution that is most present in people's lives, due to the process of evolution of technology and also because of the hyperconsumismo that is observed today, is the vehicular noise pollution, produced through sound equipment installed in motor vehicles . This form of noise propagation is perceived in an increasingly broader way in the urban environment, if it shows a very present propagating medium of noise of the modern society. Since it has a regulation that leaves the field of environmental law, it does not receive the correct service. in addition, what is observed are the municipal laws leaving to regulate this important subject, that ends directly affect the quality of life of the citizens. The city master plans regulate land subdivision and land use patterns, but they do not address the need to zonate areas of greatest impact from noise pollution and provide sites that are capable of receiving certain types of typical and common activities of modern society , such as the noise pollution of sound equipment of motor vehicles, thus leading to noise production by these equipments. This paper discusses problems related to vehicular noise pollution, starting from the study of legislation on the subject, addressing judicial decisions through quantitative and qualitative research of jurisprudence of the Court of Justice of Rio Grande do Sul, and why it is so present in society Modern. Through the hypothetical deductive method and the bibliographical and documentary research, it will be analyzed also the policies adopted in the city of Caxias do Sul, some policies adopted in other countries, showing how the city of Lisbon, in Portugal, dealt with the subject in an efficient way , and how urban law could be one of the forms of containment of this type of noise pollution that affects the quality of life of society.

Noise Pollution as a Potential Safety and Health Hazard Within Selected Utah Industrial Education Laboratory Facilities

Hicks, Carol E. 01 May 1973 (has links)
The major purpose of this study was to investigate the existing noise conditions within industrial education woodworking and metalworking laboratories to determine whether these noise conditions were a problem as seen by the instructors and if in fact these noise conditions exceeded the standards set by the Occupational Safety and Health Act (OSHA). The study was conducted in three phases: (1) the assessment of the opinions of professional industrial educators towards noise as a pollutant; (2) an electronic instrument measurement of the actual noise exposure conditions that existed in a sampling of laboratories; and (3) the comparison between the opinions of the professional educators and the actual laboratory noise conditions. The study incorporated the responses from every identifiable high school woods and metals instructor throughout Utah. Comparisons between groups were made concerning the opinions of the professional educators. towards noise as a pollutant, their knowledge about OSHA, and their identification of the noisiest pieces of equipment. The second phase of the study entailed the electronic instrument measurement of the actual environmental noise levels within 30 randomly selected laboratories. The use of a sound level dosimeter and a hand held sound level meter were employed. The data obtained from the study disclosed that the two groups were not in agreement on their knowledge about OSHA. The electronic instrument measurements revealed that 8 of the 18 woodworking instructors and 5 of the 12 metals instructors visited were subjected to noise exposures that were in violation to OSHA. The loudest pieces of equipment were the surface planer, radial arm saw, table saw, foundry furnace, pedestal grinder and portable disc grinder. The third phase of the study used a statistical analysis to compare the opinions of the instructors to the actual measured noise conditions. The chi-square test for significance at the . 05 level of confidence was used to reject the null hypothesis. The major conclusions reached as a result of the analysis of data include: (1) a potential safety and health hazard exists from noise pollution within the industrial education facilities; (2) many members of the profession are not fully informed about OSHA; (3) most labs are in compliance to OSHA noise standards, however, many do exceed the maximum a llowable limits; (4) under stringent OSHA compliance, certain curriculum alterations would have to be initiated; (5) there is no apparent connection between those laboratoryies which were in volation to OSIIA noise standards and the composition of size and construction materials; (6) the opinions of the teachers from the field do not necessarily reflect the actual measured conditions of the environmental noise exposures; and (7) the din of noise produced around machinery must not be considered a problem relevant only to industry.
