The objective of this study is to develop an enhanced methodology for analysing individuals' perceptions of discomfort due to the pressure exerted by over-ear headphones. Using principal component analysis and K-means clustering, we categorise 602 samples into six clusters and create representative Chinese head-and-ear models. A pressure tester was then developed to quantify the pressure exerted on head and ear regions by the headphone cushions. Thirty participants representing the proportional distribution of each cluster, were selected to eva...
