Uses a larger battery for longer battery life, with several options for rechargeable batteries.Includes features that don't fit on smaller style hearing aids, such as a volume control.Both are helpful for people with mild to severe hearing loss and are available with directional microphones (two microphones for better hearing in noise). Includes features that won't fit on completely-in-the-canal aids, but may be difficult to adjust due to its small sizeĪn in-the-ear (ITE) hearing aid is custom made in two styles - one that fills most of the bowl-shaped area of your outer ear (full shell) and one that fills only the lower part (half shell).Is less visible in the ear than larger styles.
This style can improve mild to moderate hearing loss in adults. Is susceptible to earwax clogging the speakerĪn in-the-canal (ITC) hearing aid is custom molded and fits partly in the ear canal.Often doesn't include extra features, such as volume control or a directional microphone.Uses very small batteries, which have shorter life and can be difficult to handle.It improves mild to moderate hearing loss in adults. The amplified signals are then converted back into sound waves and delivered to your ears through speakers, sometimes called receivers.Ĭompletely in the canal (CIC) or mini CICĪ completely-in-the-canal hearing aid is molded to fit inside your ear canal. It analyzes and adjusts the sound based on your hearing loss, listening needs and the level of the sounds around you. A computer chip with an amplifier converts the incoming sound into digital code. Small microphones collect sounds from the environment. Most hearing aids are digital, and all are powered with a traditional hearing aid battery or a rechargeable battery. Some hearing aids have a volume control (increases or decreases the volume of the sound) or a program button.Īll hearing aids use the same basic parts to carry sounds from the environment into your ear and make them louder. Hearing aids use these parts to help pick up and amplify sound from your environment and channel it into your ear: microphone (detects the sound), amplifier (makes the sound stronger), speaker (sends the sound into your ear so that you can hear it), battery (provides power to the electronic parts).
