FDA permits marketing of new laser-based hearing aid with potential for broad sound amplification
The U.S. Food and Drug Administration today allowed marketing of a new hearing aid that uses a laser diode and direct vibration of the eardrum to amplify sound. The combination of laser light pulses and a custom-fit device component that comes in direct contact with the eardrum is designed to use the patient’s own eardrum as a speaker and enables amplification over a wider range of frequencies for some hearing impaired persons. The EarLens Contact Hearing Device (CHD) is indicated for use by adults with mild to severe sensorineural hearing impairment.
