The onsite anechoic chamber provide the DARcorporation engineers with the capability to perform experimental analyses of propeller, ducted fans and vehicle noise, as well as the capability to validate and benchmark analytical acoustic analyses. Using first-order acoustic analytical tools, the noise characteristics can be obtained as a function of fan angle. The physics-based high-fidelity simulation tools we use predict the sound pressure levels at various propeller/ducted fan working conditions. With an on-site acoustic chamber and acoustic testing instruments, we can measure and compare the acoustic/noise signature of different propellers and ducted fans. These measurements allow us to help customers design/select the quietest propeller/ducted fan possible.
