Overview (resum en anglès):
This Final Degree Project addresses the modelling and simulation of the acoustic impact associated with airport take-off operations, with the aim of analysing how noise exposure varies when operational parameters such as runway capacity and fleet composition are modified. The work is based on the issue of aircraft noise as a relevant environmental and social impact in airport surroundings, especially in scenarios involving air traffic growth and urban proximity. Within this context, a MATLAB-based simulator has been developed for the comparative analysis of scenarios, not as an official regulatory assessment tool, but as a simplified model capable of identifying trends, sensitivities and spatial patterns of acoustic impact.
The methodology combines a theoretical review of acoustic fundamentals, noise metrics, prediction models and mitigation measures with the implementation of a computational model based on a straight take-off trajectory, a regular receiver grid and an energy-based calculation of sound contributions. The simulator uses aircraft reference noise levels and applies a geometric distance correction, adding the contributions of different departures in the linear domain before converting them back into decibels. On this basis, time-based plots at specific points, three-dimensional representations, noise contours, areas affected by acoustic thresholds and parametric sweeps of capacity and percentage of Heavy aircraft are generated.
The results show that an increase in operational capacity raises the accumulated acoustic exposure, although this effect is not distributed homogeneously across the grid. The relative position of the receiver with respect to the trajectory clearly determines the acoustic sensitivity of each point. Likewise, the increase in the percentage of Heavy aircraft produces a significant increase in the system response, with steeper slopes and a reduction in the capacity required to reach certain noise thresholds. The analysis using thresholds of 65, 60 and 55 dB makes it possible to transform accumulated exposure into more interpretable comparative indicators, identifying which areas reach each acoustic criterion first and how the affected area expands as the considered threshold is reduced. Overall, the simulator proves to be a useful tool for exploring operational scenarios, comparing trends and providing preliminary support for understanding airport acoustic impact from a spatial, temporal and operational perspective.
