Coupling Methods
- Headphone or Stetoclip - for persons with auditory processing problems but normal hearing
- Bone Oscillator - for persons with malformed ear canals or draining ears
- Button Earphones - allow for the greatest power
- Behind-the-Ear - microphone, amplifier, receiver, battery, and oscillator contained in the BTE case
- Personal Hearing Aid via:
- direct-input - electrical signal from FM receiver led directly into HA via a boot or audio-shoe connection
- silhouette - requires a HA with a T-coil and an electromagnetic field is created in a wafer-shaped piece worn between the head and the HA
- neckloop - electrical signal from FM receiver delivered to neckloop that creates an electromagnetic signal which is picked up by the T-coil of the HA and amplified
