Abstract
Local effects of noise mitigation are preferably researched with high-fidelity tools rather than standardized noise models. The added advantage is that it is even possible to actually listen to the audible results from these tools. Such an audible result can be generated with the help of noise synt hesis techniques. Aircraft noise synthesis, based on separate modeling of airframe and engine noise components, is described in this study for the use in a virtual reality noise simulator. The present study also shows the effect of atmospheric wind to a synthesized take-off procedure. This was studied in order to quantify the role of the wind in a previous comparison between measurements and synthesized results. The present analysis shows that there is an impact of the wind on the audible result. Hence, the modeling of wind effects can be important to bring measurements and simulation more inline. However, given the current mild wind case, the impact is relatively small. Therefore it is concluded that the observations from the previous research, the comparison without wind effects, will still hold.
