ABSTRACT
This study shows noise levels of CTA Brown Line and recommendations for noise reduction in Central Business District, residential areas and retail areas. Noise levels in Brown Line are serious problems like environmental pollution, when trains passed to measuring points. Noise levels (LAeq) were 79.4 ~ 87.5 dB depending on geographical aspects. Also maximum noise levels (LAMax) were 84.2 ~ 93.0 dB when trains passed.
There are several methods to mitigate noise levels depending on land use and circumstances of areas. Barriers, vegetation, buffers, setbacks, site design, unit design, building design and building facades can be applied to individual areas. So we can expect reduction of noise levels in ambient residential buildings and houses near Brown Line railroads. What expectations of reduction of noise levels if the methods are implemented are considered is 5.0 ~ 25.0 dB depending on different methods.
