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.
