Different types of hearing aids are intended to treat different amounts of hearing loss. A trained hearing doctor, or audiologist, will be able to look at your hearing test results to determine whether your type of hearing loss can be treated with hearing aids, and which hearing aids are most appropriate for your hearing needs. Oftentimes, someone with severe hearing loss will not know that someone has spoken to them unless they are facing the speaker directly. Sounds that are just audible to someone with severe hearing loss will usually be quite loud to someone with normal hearing.
If you have severe hearing loss, you may not be a good candidate for certain hearing devices, since some are only intended to treat mild to moderate levels of hearing loss. However, some hearing aids can treat a wide range of hearing losses. For example, the Earlens Light-Driven Hearing Aid is intended to treat mild to severe hearing loss.
People with severe hearing loss may particularly benefit from the Earlens Hearing Aid because Earlens can provide higher levels of amplification across a broader range of frequencies before encountering feedback or whistling that traditional hearing aids often suffer from. This means that users with severe hearing loss who may have been missing sounds in the higher frequencies, like some high-frequency consonant sounds in speech, may find themselves able to hear them again.
How can Earlens provide these benefits? Unlike traditional hearing aids, Earlens does not rely on a speaker to transmit sound. This is important because speakers are constrained in their bandwidth as well as the amount of amplification they can provide before sound distortion occurs. Earlens uses a new proprietary technology to use light to transmit sound information.
In Earlens, a microphone in the behind-the-Ear Processor captures sound, which is converted into pulses of non-visible light that directly vibrate a custom Lens placed on the wearer’s eardrum. Because it directly vibrates the eardrum, Earlens can provide more gain (or amplification) before feedback than traditional hearing aids, and can also amplify sound across a broader bandwidth, which has been associated with the perception of more natural sound quality*.
If you have severe hearing loss, speak to an Earlens provider to see if Earlens could be right for you.
The Earlens Light-Driven Hearing Aid is one of the best hearing aids for providing audible amplification across a broad frequency range. Earlens is a digital hearing aid that uses light to transmit sound for the most complete hearing available from a hearing aid. Earlens automatically adjusts to noisy environments and uses a rechargeable battery with wireless charging for enhanced ease of use.
