The problem of noise as a potential health hazard to urban man has been raised. The literature was used to establish two premises: that cities are noisy environments, and that noise-free societies have less coronary artery disease (CAD) than do industrialized sections of the world. These differences also hold for rural and urban areas of the United States. Geographical questions concerning rate differentials for CAD have been addressed by numerous disciplines. Subsequently, social, psychological, and physical explanations have been put forth. Throughout this paper the emphasis has been placed on the physical aspects of noise exposure. The conceptual frame utilizes noise-load, overload, stress and deformation. Noise was described as a force capable of eliciting a predictable physiological response from the human organism. Noise was further conceptualized as a by-product of technology which exerts a stressor effect upon the cardiovascular system of man. The investigation, from which the data were generated, was a micro-view of physiological effects, in that the only measurement taken was heart rate change in hospitalized patients in response to noise. The heart rate was calculated under low noise conditions, and comparisons subsequently made to heart rate during noise. In addition, the noise climate for each of two coronary care units (CCU) was tabulated over a 24 hour period. Generally noise levels in the CCUs were higher than might be found in a man's own home. Only between the hours of 3:00 and four in the morning, was ambient noise equal to or below the suggested levels (45 dbA) for any sustained period of time. Conditions of noise elicited heart rate change in 30 of 37 subjects (p=.001). This finding relates to the presence of a change and does not speak to the extent or meaningfulness of that change. Patients with heart attacks responded to noise conditions (11=18, P=.01) in that 17 of the eighteen patients experienced a change in heart rate when noise was introduced. No differences could be noted for categories by site of infarctions. It was further hypothesized that the extent of heart rate response (HRR) would be a function of the gap between low noise and high noise conditions. A regression analysis showed the response to be significantly correlated with noise gap for the total population (N=37, P=.05), however the correlation was minimal (r=.4528) with slightly less than 21 per cent of the variation in HRR explained by the variation in noise gap. Those subjects more than 60 years of age (n=20), also showed a significant correlation (r=.5173) with 26 per cent of the variation in HRR explained by the variation in noise gap. The highest correlation (r=.7373) was obtained for ten persons with a past history of heart disease (r2=.5436, P=.05). The implications for site planning and structure are many, particularly for hospitals, nursing, and convalescent homes where older persons with heart disease are housed. Site planning should give attention to noise environment; and structural planning, to sound-proofing. Interviews with architects and hospital builders showed this goal to be attainable mechanically, if somewhat costly. It was agreed by those interviewed that such costs as evolve from noise-reduction or noise-proofing in hospitals would most certainly be passed on to the consumer and be reflected in his health care costs. Additional research is needed which focuses on the effects of noise on the cardiovascular system over time, using standardized criteria for cardiovascular health and cardiovascular disease. Other research might focus on larger samples of patients hospitalized with CAD, in an effort to identify an index of physiological and psychological responses to noise.

Fundação Araucária / O ruído urbano vem sendo cada vez mais uma grande preocupação para a sociedade moderna. Diante disto, este estudo de caso tem como objetivoelaborar um mapa acústico com os níveis de pressão sonora da região central de Curitiba e principais vias de acesso ao centro, a fim de se conhecer quais níveis de ruído estão expostos os cidadãos e trabalhadores e identificar áreas com valores sonoros acima dos permitidos pela legislação. A metodologia adotada para a confecção do mapa acústico desta pesquisa tem como referência a norma NBR 10151, a qual estabelece critérios para os medidores de pressão e para as condições de medição. Na primeira fase foram feitas medições dos níveis de ruído presentes em 416 pontos do centro da cidade e das principais vias de acesso ao mesmo. Posteriormente levantou-se a altura das edificações de toda a região mensurada para confecção do mapa acústico por meio do software CADNAA. Os resultados obtidos foram comparados com a Lei Municipal Ordinária de Curitiba nº 10625, de 19 de dezembro de 2002, a qual define que no período diurno (07h01min até 19h00min) o limite de pressão sonora é de 65dB(A) para a zona central, e mostraram que todos os pontos de medições estavam acima do limite permitido pela referida Lei. Concluiu-se que o mapa acústico é uma ferramenta visual muito interessante para visualização dos níveis de ruído em determinado local e que Curitiba precisa tentar se precaver, pois os valores de ruído encontrados superam o limite de sua Lei municipal. Desta forma recomendam-se ações simples e objetivas como a utilização de motores híbridos para frotas de ônibus e caminhões. / The urban noise has been increasingly becoming a major concern for modern society. Given this, this case study aims to map the acoustic sound pressure levels in the central region of Curitiba and main access roads to the center in order to know what levels of noise exposed workers and citizens identify and areas with sound values above those allowed by law. The methodology adopted for the preparation of this research has acoustic map as a reference to NBR 10151, which establishes criteria for pressure gauges and measurement conditions. In the first phase measurements were made of the noise levels present in 416 points of the city center and the main access routes to it. Later raised the height of buildings across the region to prepare for the measured acoustic map through software CadnaA. The results were compared to Ordinary Curitiba Municipal Law No. 10,625, of December 19, 2002, which states that during the daytime (07h01min 19:00 until) limit sound pressure level is 65dB (A) for the central zone. In conclusion it was found that all points of measurement are above the limit allowed by local law. Thus actions are recommended simple and straight forward as using hybrid engines for trucks and bus fleets.
