Modeling of the octave sound spectrum emitted by the F-16 Block 52+ aircraft during takeoff

Untitled

“…In relation to a single flight operation, such as takeoff, cruise and landing, another index of objective noise nuisance applies -a noise A exposure one: L AE [37,51]. It appears as though instantaneous oscillations of the acoustic pressure are a very good parameter in the consideration of the discussed problem as well as the qualitative structure of the generated signal, as has been confirmed in [48]. In [17] a continuous measurement of noise in the vicinity of the Ben-Gurio airport was carried out, taking into account different types of aircraft, its operating conditions (aircraft height and takeoff time) and the weather.…”

“…One of the still unsolved problems related to the aircraft noise measurement is the assessment of the level and structure of noise in different examples of the same aircraft. It is generally known that each of them generates different level of acoustic pressure, mainly due to different technical, operating and weather conditions [17,48,49]. The evaluation of different types of noise can be presented in many ways.…”

Machine Learning and Prediction of Masked Motors With Different Materials Based on Noise Analysis

“…Satisfactory noise prediction results were obtained in the aforementioned study. In another study, a machine-learning-based method was used to predict the noise level in the surroundings of an F16 fighter jet taking off, and a time-frequency diagram was used for analysis and evaluation to understand the effectiveness of the developed machine learning model in terms of environmental noise prediction [7]. Because the numerical analysis of wind turbine noise levels is extremely challenging and timeconsuming, the use of machine learning techniques is preferred for noise estimation [8].…”
