Abstract
Sustainable aviation is achieved when the negative impact of aviation on people, planet, and profit is minimised. Aviation impacts people through the noise it produces. Exposure to high noise levels for prolonged periods of time can lead to sleeping disorders, hypertension, and hearing issues. Therefore, the new generation of aircraft should be designed such that the noise emissions are reduced. Additionally, reducing noise annoyance is important as the human perception of aircraft noise is not only influenced by sound pressure levels.
Reducing the noise emissions and annoyance is only possible when the noise sources of an aircraft are known and can be predicted accurately during the design process. The objective of this dissertation is therefore to improve aircraft noise prediction models that can be used for reducing noise emissions and noise annoyance in the design process. This is specifically applied to currently operational sustainable aviation systems.
