Brief Summary

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 over a prolonged duration in a sample of individuals with bilateral hearing loss. It will also compare how long each method takes to make and how much each costs.
