FDA Approves Sale of Laser Hearing Aids
Some interesting news regarding the sale of laser hearing aids.
News in Brief | February 2016
The U.S. Food and Drug Administration recently approved the marketing of a hearing aid that uses a laser diode and direct vibration of the eardrum to amplify sound.
The device uses a phenomenon known as the optoacoustic effect, in which some of the photons of certain types of light are absorbed and their energy is transformed into sound-generating waves when the light strikes a surface. About 10 years ago, scientists began exploring how this ability to “hear” light could be used in hearing aids.
