About the EarLens Light-Driven

The EarLens Contact Hearing Device is a radically different type of hearing aid that uses light, and an eardrum vibration lens - rather than amplified sound - to move the eardrum.

The EarLens itself is a custom-fitted eardrum vibrator (or "tympanic-membrane transducer"), which is created using a mold of the user's ear. The EarLens is "floated" on top of the user's eardrum using a thin layer of mineral oil. On its own, the EarLens vibrator is not capable of doing much. However, when stimulated by infrared light, the EarLens kicks into action, and begins to vibrate.  When the EarLens vibrates, the user's eardrum vibrates in synchrony, producing audible sound. 

The microphone for the EarLens is fitted inside the earcanal, along with a light emitting diode. This allows the EarLens microphone to pick up sound from a very natural position (as close to the eardrum as possible), which overcomes the need for a directional microphone. As described in the Features and Benefits section below, sound coming from the front of the listener is naturally amplified by the outer ear (pinna), so picking sound up inside the earcanal is the best place to pick up sound (to be amplified). Background: When people have a conversation, they usually face each other, so sound from the front is considered the most important. 

Importantly, the earcanal is left completely open with the EarLens system. This alleviates any sense of "blocked ears" which might accompany traditional (non-open-fitting) hearing aids. One of the consequences of open-fitting hearing aids typically is excessive acoustic feedback. The EarLens system is less susceptible to this issue, since there isn't a speaker emitting very loud sound in close proximity to the speaker.  Another consequence of open-fitting hearing aids is reduced low-frequency amplification (less low pitch boost). This is due to the leakage of lower pitch sounds through the open canal, and the difficulty of producing low-pitch sound using tiny hearing aid speakers. The EarLens system is not susceptible to these issues since the eardrum is vibrating directly with lower frequency vibrations (~200Hz).

EarLens Light-Driven Reviews

Hearing aid reviews are fundamentally different from reviews for most other consumer electronic products. The reason is because individual factors, like degree of hearing loss, have a profound effect one's success and overall satisfaction with the product. When purchasing a hearing aid, you'll need to consider more than just your hearing outcome. Hearing aids are manufactured with varying levels of quality; some hearing aids are extremely durable, while others suffer frequent breakage. Battery life also varies between models, and manufacturer predictions of battery life are often optimistic. By collecting feedback from consumers, we can get a better idea of real world product durability and battery life... Continue reading

How does it compare to your other hearing aid though? Is it an improvement?

How much is the hearing aid
Ken P.
Ken P. 07 September 2017
Understanding the device is rechargeable, can a standard battery be used if not convenient to recharge, if so what size battery does the Earlens light-driven hearing aid use and how long do they last? Is a cone used in the ear to support the inferred light device mounted behind the ear? How is the aid removed that sits against the eardrum? How often should you remove the device from the eardrum? Does ear wax effect the device? I'm assuming the behind the ear piece is rechargeable, overnite? How much are the hearing aids? Warranty? How long does it take to get fitted sense they are custom (piece against the ear drum)? Is there any need for adjustments by computer as with example Opticon I currently use?

What about ear wax build up and wax removal. It’s easy outpatient procedure for the lens positioning on the ear drum? Does hearing aid have Bluetooth connectivity
