Highlights • “Two-Staged Structural Equation Modeling-Artificial Neural Network” model is used. • Sensitivity, hours, profession, sleeping disorder, and education affect annoyance. • Sensitivity is found to be the most important predictor and education the least. • Socio-demographic factors affect annoyance, sensitivity, and sleeping disorders. • These factors indirectly affect annoyance via sensitivity and sleeping disorder.

Abstract The “two-staged Structural Equation Modeling-Artificial Neural Network” approach was used in this study to assess the annoyance caused by traffic noise in 158 people. The SEM-Partial Least Squares path revealed that sensitivity, exposure hours, profession, sleeping disorder, and education significantly affect annoyance. The variables, such as age, experience, gender, and Leq are found to be inconsequential. The measurement model confirmed 67.5 percent of the variance in annoyance. However, the effectiveness of the Artificial Neural Network model is justified by observing the Mean Square Error and Root Mean Square Error values, and the model's accuracy is 71.2 percent. Furthermore, the feed-forward back-propagation ANN approach confirmed that noise sensitivity is the most important predictor of noise annoyance, followed by exposure hours, profession, sleeping disorder, and education. The SEM-PLS path also revealed that combined socio-demographic factors affect annoyance indirectly through noise sensitivity and sleeping disorder and directly affect annoyance, sensitivity, and sleeping disorder.
