The HiSonic Head Gear provides the wearability of a bone conduction hearing device for the profoundly deaf.
The HiSonic hearing device enables a profoundly deaf person, who would derive little or no benefit from conventional hearing aids, to hear. The device converts speech and sound into ultrasonic vibrations. These vibrations, when transmitted by a transducer to the mastoid bone behind the ear, are perceived by the brain as sound. The transducer is held to the mastoid by the HiSonic Head Gear.
