Syntheses of aircraft noise obtained by computational methods

In ANIMA WP4, where focus is put on toolset development, a benchmark on three partners’ auralization tools was performed.

These tools are used to reproduce the sound of an aircraft flyover from either physical modelling of noise, a prediction based on measurement or a combination of both. As the chosen methodologies and the modelling hypotheses are different between partners, a benchmark was performed to assess the impact of these strategies on the produced sound synthesis.

The realism of each auralization was evaluated through comparison to experimental recordings. For propriety reasons, only the synthesized sounds are available here, and can be compared between each other.

Two of the three tools were further used in the WP3 task dedicated to Virtual Reality, see "Virtual reality simulated aircraft flyovers: Influence of the landscape on the overall pleasantness of the environment"

The sounds represent three flight configurations, one landing, and two take-offs with different engine speeds. Two aircraft are considered, one single-aisle and one double-aisle aircraft. The synthesis is performed at a receiver position below the aircraft trajectory.
