Earlens FAQ: How Does Earlens Transmit Sound?


Unlike conventional acoustic hearing aids, Earlens does not transmit sound through a speaker.


The Earlens® Contact Hearing Solution consists of 3 main parts: the rechargeable Processor, the Ear Tip, and the Lens. The Processor is worn behind the ear. It captures sound from the outside world, enhances the sounds and sends it to the Ear Tip. The Ear Tip is worn inside the ear canal and transforms sound received through the Processor into pulses of energy. Those pulses of energy activate a small, custom built Lens worn on the eardrum, to vibrate the eardrum in the same way that it would organically vibrate with sound waves. Since the Lens is driven by the energy produced by the Ear Tip, the Lens itself does not require any batteries.


Earlens works very similarly to the natural hearing system by directly vibrating the eardrum instead of sending amplified sound waves through a speaker. The eardrum’s movements vibrate the middle ear bones, which stimulate the tiny hair cells in the inner ear to signal the hearing nerve. When the brain receives messages from the hearing nerve, we perceive sound.
