    Open-Fit Hearing Aids has a few primary benefits:

    • Because the ear canal is left open, low-frequency sounds come through with much greater clarity.

    • Hearing aids that block the ear canal can cause the user to feel their own voice is somewhat distorted or muffled due to the blockage. Open-fit hearing aids do not have this drawback.

    • Given their small size, they tend to be less susceptible to blockages due to earwax.

    • There is little to no telephone feedback when using an open-fit hearing aid.

    • They can potentially be a good fit for individuals who are somewhat sensitive about their hearing impairment, as they are less immediately noticeable.

    How Do Open Fit Hearing Aids Work?

    An open-fit hearing aid functions in essentially the same way as any other assisted hearing device. The hearing aid picks up sounds through a receiver, located either on the main body of the hearing aid or within the ear. This sound is then fed through an amplifier, and then finally sent through a speaker.

    Coupled with recent advancements in digital feedback suppression, this allows open-fit hearing aids to function with a remarkable level of clarity.


    How can hearing aids help?

    Hearing aids are primarily useful in improving the hearing and speech comprehension of people who have hearing loss that results from damage to the small sensory cells in the inner ear, called hair cells. This type of hearing loss is called sensorineural hearing loss. The damage can occur as a result of disease, aging, or injury from noise or certain medicines.

    A hearing aid magnifies sound vibrations entering the ear. Surviving hair cells detect the larger vibrations and convert them into neural signals that are passed along to the brain. The greater the damage to a person’s hair cells, the more severe the hearing loss, and the greater the hearing aid amplification needed to make up the difference. However, there are practical limits to the amount of amplification a hearing aid can provide. In addition, if the inner ear is too damaged, even large vibrations will not be converted into neural signals. In this situation, a hearing aid would be ineffective.
