Therefore, information on noise levels is needed to determine the noise distribution at Sultan Aji Muhammad Sulaiman Airport in Balikpapan. The noise contours in this study were based on flight data over five days. According to the study, the total noise-affected area at Sultan Aji Muhammad Sulaiman Airport is 0.039 km², with residential areas located 2 km from the runway. Planting noise-dampening trees around residential houses can help reduce noise levels.From the evaluation and data analysis, information such as flight schedules and airport noise data were obtained.
