Validation of the Acoustic Finite Element Model of a Very Light Jet Cavity Mock-up

This paper presents an important step in developing a combined active noise- and audio system for a (very) light jet. To prepare its installation both a wooden mock-up and a finite element model of the investigated cavity were created. Sensitivity analysis and key parameters selection were done in order to validate the model. Error analysis between measured and computed data closes the investigation. The simulations were performed using COMSOL Multiphysics vers 3.4. The validated model could be used to optimize the loudspeaker- and microphone positions.
