Aircraft route optimization is key area in which the airlineindustry is focusing. The optimization of the route results in the reasonable profit along with the considerable aviation noise.Aviation noise can never be completely avoided around but it can be reduced to some extent.Thepaper proposes a comparison with the four algorithms which optimizes the route along with the decibel of noise produced in that course. The results show the reduction in aviation noise when the route is optimized and the best is also obtained.
