Noise in sustainable transformation of aviation

Rising awareness of aviation noise's health and annoyance impacts does not coincide with the industry's sustainable transition which is primarily driven by climate change. While electrification and sustainable fuels are seen as solutions, current strategies often encourage aviation sector growth including airport and traffic expansion. National initiatives aim to accelerate aviation's sustainable transformation, aligning with increased transportation accessibility and mobility goals. There is a push for directives for electric aviation, drones, and urban air mobility (UAM). Local health and annoyance, however, are overshadowed by the pretense of the global focus. Increased noise is anticipated with projected increases in air travel and added noise from electric and drone aircraft! This paper integrates noise and annoyance considerations into sustainable aviation transformation. A system analysis, using soft system methodologies, reveals comprehensive socio-technical perspectives from aviation, urban planning, citizens, and regulation. Findings indicate future noise challenges and unfavorable conditions for noise reduction innovations. The study advocates for society-wide strategies to manage aviation noise and annoyance, emphasizing recommendations like careful design, operational considerations, noise simulations, and democratic community involvement in implementation. These insights anticipate a surge in noise-related complaints and opposition. This paper is of interest also for future aviation developers.
