Study 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. It will also compare how long each method takes to make and how much each costs.
Primary Outcome
Evaluation of ear canal acoustics with participant wearing a hearing aid and eartip type (3d party control, in-house\_Resin, in-house\_FlexResin). Then, a thin microphone tube is placed in the ear canal to measure the average amount gain (dB SPL) across various frequencies (250-8000Hz) while the participant sits in front of a speaker playing sound samples. Results are recorded in gain (dB SPL) across frequencies. Once complete, the eartip type is changed and recording is repeated until all earti
