Bone conduction hearing system and open source application: One alternative for patients with hearing loss

Abstract:

In this work, a low-cost hearing assistance system is presented with the use of conventional type skin-operated bone conduction headphone designs, created with technology by deposition of molten material in a 3D printer and use of an audio receiver from cellular devices. Sound is captured, processed and filtered for later transmission to the designed hearing aids. This alternative was created to assist children with moderate-grade conductive hearing loss. The system, for its use, uses an open source application "UYARINA". The characteristics of the system, the designed headphones, the application developed, the results and its performance tests in children between 8 and 12 years old are presented.
