Noise disturbance quality standards which refer to Indonesian Government Decree number 22 of 2021 concerning Environmental Management in the future will be drawn up. This possibility has prompted several local governments to measure and map noise in their respective areas. The commonly used pattern in noise studies is taking grab samples and processing the test sample data using extrapolation techniques in order to obtain long-term noise levels. The approach requires a sufficient literature base. This study analyzed noise based on daily data at three different locations in the City of Jakarta, Indonesia. The three locations were construction site, industrial area and along inner-city toll road. Analysis of ANOVA variance at daily and hourly levels for 42 LA eq was presented in this study. Statistical results showed significant differences between hourly and daily periods, so further attention is needed on the extrapolation approach that represents long-term noise levels. The longer the noise analysis period in an area, the more accurate the characterization of noise in the study area will be.
