Overview
Access to affordable and timely hearing healthcare remains a major challenge for many individuals, partly due to the high cost and long turnaround time. This study will explore whether 3D-printed ear tips perform as well as or better than standard ear tips in terms of sound quality, comfort, and fit. It will also compare how long each method takes to make and how much each costs.
