Hearing aids are a common non-invasive treatment option for hearing loss. A hearing aid is a small electronic device worn in or behind the ear to amplify sounds. While hearing aids are useful in improving listening and communication, they do not cure hearing impairment or make the ear function normally.
A hearing aid is composed of three components: a microphone, an amplifier and a speaker. Sounds are received through the microphone, intensified by the amplifier, and transmitted to the ear through the speaker. The microphone, which picks up sounds from the air, converts them into electrical signals. Once these sounds have been made more powerful by the amplifier, they are changed back into acoustic signals to be heard by the person wearing the hearing aid. In addition to these three components of hearing aids, digital hearing aids also make use of a small computer.

These hearing aids are worn behind the ear and connected to a plastic mold that is placed inside the outer ear. They are utilized by individuals with mild to profound hearing loss. New technology has introduced a smaller BTE aid consisting of only a small tube placed into the ear canal. This has the advantages of keeping the canal open and protecting the device from damage due to wax buildup. This smaller BTE also provides a clearer sound.
These hearing aids are smaller devices that fit inside the outer ear. They can be used for mild to severe hearing loss but are not typically used for children since they will be quickly outgrown.
Canal aids are the smallest type of aid and fit either in the canal, ITC, or completely in the canal, CIC. Because canal aids are so small, they may be hard to adjust and have very limited space for batteries and other devices. Canal aids, therefore, are most frequently recommended for individuals with mild to moderate hearing loss.
Regardless of style, hearing aids work in two different ways depending on how they are electronically programmed.
These aids convert sound waves into electrical signals which are then amplified and transmitted back to the ear. They can be custom-made to fit each patient's hearing needs. They can altered by the patient and customized for different listening environments. Analog aids can be used in any style of hearing aid.
Digital hearing aids convert sound waves into numerical codes and then amplify them. Some frequencies can be amplified more than others. Digital aids can also be programmed to focus on sounds coming from a certain direction. These aids tend to be more expensive than the analog variety.
