Definition of Hearing Aids: Hearing aids are small electronic devices designed to amplify sound for individuals with hearing loss. They are worn in or behind the ear and help improve the wearer's ability to hear and understand speech and sounds. Hearing aids consist of various components and are available in different types to accommodate different degrees and types of hearing loss.
Types of Hearing Aids:
- Behind-the-Ear (BTE): These hearing aids rest behind the ear and are connected to an earmold or a small tube that directs sound into the ear canal.
- In-the-Ear (ITE): ITE hearing aids are custom-made to fit in the outer portion of the ear and are suitable for mild to severe hearing loss.
- In-the-Canal (ITC) and Completely-in-the-Canal (CIC): These are smaller, more discreet hearing aids that fit partially or completely inside the ear canal.
- Receiver-in-Canal (RIC) or Receiver-in-the-Ear (RITE): RIC/RITE hearing aids have the receiver or speaker placed inside the ear canal, connected to the device behind the ear via a thin wire.
Parameters and Components:
- Microphone: Picks up sound from the environment.
- Amplifier: Processes and increases the volume of sound.
- Receiver: Transmits amplified sound into the ear canal.
- Battery: Powers the hearing aid.
