Comparison Auralization vs. Measurements of V2500 engine flyover at take-off conditions

Illustration of engine noise auralization by DLR Institute of Propulsion Technology obtained with the framework PropNoise, VIOLIN, CORAL. Data associated with publication: “A framework to simulate and to auralize the sound emitted by aircraft engines.” paper Nr.  C001073, InterNoise Conference, Chiba, 2023 by A. Moreau, A. Prescher, S. Schade, M. Dang, R. Jaron, S. Guérin.

Examples of audio files for the simulation and auralization of two engine flyover experiments at take-off conditions (V2527 engine powering A320 civil aircraft):

• Flyover A – experiment on DLR LNATRA research aircraft, measurements are monaural and taken with a microphone placed wall flush with the ground (no ground reflections)
• Flyover B – experiment at Berlin Airport, measurements are taken at 1.2m above ground with an artificial head equipped with two microphones, binaural recording and ground reflection.

Sound amplitude levels have been normalized.
