Yogyakarta as a city of education becomes one of the destination for young people who want to pursue a university level degree. Their arrival increased the number of Yogyakarta’s population. In Indonesia, the increment of population is followed by the increment of vehicles. Meanwhile, the result of having a lot of amount of vehicles is not followed by the streets capacities and therefore causes traffic jam. Traffic jam creates a high noise level which is produced from vehicle engine, horn and muffler. This noisiness might distract some learning activities and create inconvenient education environment.
