 The study examined the impact of noise pollution on the visual and acoustic landscapes of two parks in Curitiba, Brazil. Three transects were established, each representing varying levels of vegetation density. Visual quality was assessed using a direct method for evaluating landscape elements, while noise levels were measured by two instrotherm decibel meters. The results indicated that higher levels of vegetation resulted in lower noise levels, with the highest levels of noise reduction occurring at Site C. Additionally, a strong correlation was found between the visual quality of the landscape and the amount of noise attenuation. This suggests that vegetation can be used to reduce noise levels, particularly when it is dense enough to block out the noise.
