The effect of distance of noise level in a residential area (case study: residential area that close to Jagorawi highway and Pandu Raya road in Bogor City)

摘要

Bogor city is a city that continues to experience in population growth and physical city development, where the development creates various kinds of problems, which one is noise. This study aim to measure the noise level and analyse the influence of noise level and house distance from noise sources. Data retrieval was collected for three days a week. In one day, noise measurement was carried out for 16 hours (06.00 - 22.00) by measuring the sound pressure level for 10 minutes for each 27 measurement points. The results showed that the noise level in weekdays higher than weekend, with averaged 87.25 dB. In accordance with standard, the noise level of residential area is 55 dB, it means the noise level is above the noise threshold. Based on the regression analysis, the R square of housing is 0.76, the linear equation is Y = 77.656 - 6.292x. The study concluded that the distance affects the value of noise, the closer to the noise source the greater the noise value.
