Abstract:
The objective of this paper is to present a method of determination of airport noise levels and environment noise using computer simulation, thus reducing the need for physical measurements in the areas affected by airport noise.Through the simulations, the hourly airport noise was characterized for a wide range of critical receivers. Levels for airport and environment noise had been calculated, considering that environment noise is generated mostly by the flow of motor vehicles on the nearby roads. From the results of these simulations it was possible to choose points where continuous noise measurements are made.Using the simulated values, we hope to determine a safe and precise way of predicting the noise generated from airports throughout the country minimizing the needs of conducting physical measurements to obtain the noise curves.To simulate the noise caused by the aircrafts, it was used the simulation software INM, and for the environmental noise, the software CadnaA was used due to its easiness of use for this particular type of noise source. INM was used to simulate air traffic because our CadnaA package didn't have the air noise simulation upgrade.The noise levels values are then used to conduct a preliminary diagnosis in relation to the NBR 10151.The case study is presented for the Santos Dumont airport located in Rio de Janeiro, Brazil, during the month of January of 2010.
