What is a hearing aid?

Hearing aids are small electronic devices that can be highly customized to address different types of hearing loss. All digital hearing aids contain at least one microphone to pick up sound, a computer chip that amplifies and processes sound, a speaker that sends the signal to your ear and a battery for power. More sophisticated models provide additional features, such as direct connection to a smartphone or neural networks.

How Do Hearing Aids Work?
Hearing aids work by amplifying sound through a three-part system:
The microphone receives sound and converts it into a digital signal.
The amplifier increases the strength of the digital signal.
The speaker produces the amplified sound into the ear.

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.
