“…The NASA Auralization Framework (NAF) and the NAF advanced plugin libraries 28 offer the means to auralize system noise predictions of aircraft flyovers according to the methods described by Rizzi and Sahai. 27 The ANOPP2-NAF interface library 29 allows source definitions from the system noise prediction (stored in ANOPP2 observer restart files) to be read by a NAF user code. A method 30 for synthesizing buzzsaw noise was developed and implemented in the predecessor synthesis code ASoNG.…”

“…Different synthesis methods are used for broadband and tonal noise components. 27 Propagation to the receiver is performed through application of a distance-dependent, negative gain (for geometrical spreading), a timevarying delay line (simulating Doppler frequency shift), and finite impulse response (FIR) filters for atmospheric absorption and ground reflection. Convective amplification is included in the ANOPP2 source definition.…”

The Aircraft Noise Simulation Working Group (ANSWr), comprised of NASA, DLR, and ONERA, recently completed an analysis campaign to compare aircraft noise simulation tools, establish guidelines for noise prediction, and launch activities to assess uncertainties associated with the simulation. The campaign included the analyses of two DLR conceptual aircraft, a reference tube-and-wing aircraft, and a low noise aircraft with engines mounted above the fuselage-wing-junction. While the total predicted noise for each of the concepts compared favorably among analyses at the peak level, significant differences were noted at the component level. This paper aims to further that effort by auralizing aircraft flyover noise associated with those predictions. Comparisons are made among the NASA, DLR/Empa, and ONERA generated sounds to determine how differences between the system noise prediction and auralization methods result in changes to the auralized sound.

Based on the outcome of a workshop on aviation noise, this special issue on aircraft noise generation and assessment has been assembled. Invited contributions on preselected topics have been combined into one overall story line about both the aircraft noise generation and its assessment to provide an overview on the state-of-the-art capabilities in this research field (accounting both for modelling and measuring efforts). Although most relevant topics are covered, the editors do not claim that the collection of contributions is exhaustive for the multidisciplinary and vast research area dealing with aircraft noise. This issue is not restricted to current aircraft technology only, but includes low-noise technologies and novel aircraft design for subsonic and supersonic vehicles. Furthermore, an overview on measurement techniques, aeroacoustic windtunnel design, and low-noise modifications to existing windtunnels is provided. The selected paper contributions are all peer reviewed and display the status quo of experimental and numerical research activities in academia, at research institutes, and in industry.

The world is currently undergoing a significant transition towards cleaner and more sustainable energy sources. The transportation sector is gradually moving away from fossil fuels and electric vehicles, both on the ground and in the air (e.g., drones), are more and more common. The introduction of these electric vehicles will bring new sources of transportation noise, which might lead to the largest shift in soundscapes in living memory. This soundscape shift could be detrimental to the public health and well-being if appropriate actions are not taken. This chapter presents the state-of-the-art of the fast-developing field of transportation noise, and discusses current practice gaps and recommendations.
