AbstractThis project designs, builds, and evaluates a pre-production prototype of a hearing aid using a three-axis telecoil assembly. Telecoils in hearing aids serve a dual purpose: (1) to enhance telephone conversation, and (2) enable hearing aids to serve as a wireless interface for public audio broadcasts. When broadcasting audio signals, the signal is transmitted to the telecoil sensor (a magnetic field sensor located in the hearing aid) via magnetic energy from an induction wire loop located near the listener. This induction loop can be a small assembly located in the handset of the telephone or a large wire loop within a public venue like a theatre. The design utilizes digital signal processing algorithms to process the magnetic transmissions from the induction loops.
