Hearing Aid An amplification device worn in or around the ear. There are many varieties of hearing aids, but each type consists of four parts:

  • Microphone: receives the sound signal and sends to amplifier.
  • Amplifier: increases the intensity, or loudness, of the signal.
  • Receiver: sends the amplified sound into the ear canal.
  • Battery: provides power to the hearing aid.The following types of hearing aids are available and differ in function, appearance, and cost.

An audiologist provides suggestions and prescriptions for aids that best suit the individual’s needs, considering type and degree of hearing loss and age of patient.

  • In-the-Canal (ITC): a small aid that fits inside the ear canal. Similarly, the smallest aid is the Completely-In-the-Canal (CITC).
  • In-the-Ear (ITE): an aid that fills the outer part of the ear, with all of the components housed in its plastic body outside of the canal.
  • Behind-the-Ear (BTE): an aid that hooks onto the ear lobe, with the components housed in the plastic shell behind the ear. The aid hooks onto a plastic earmold in the outer ear. Typically used by children due to larger size and to allow room for growth.
  • Body Aid: a rectangular case contains the hearing aid components and connects to a receiver on the earmold in the outer ear. The case is worn on the body in a pocket or pouch.
  • Bone Vibrator Aid: an aid that is held against the mastoid bone behind the ear and sends vibrations from the sound signal to the inner ear. Most helpful in people with conductive hearing loss.

Hyperkeratosis Is a benign build up of tissue (precancerous lesions) that cause hoarseness. These lesions appear as irregular thickening of the vocal folds. They have a distinctive leaf-like appearance and typically show some discoloration. Lesions that go beyond the outermost layers are at a high risk of developing into cancer. People who get these lesions are instructed to avoid smoking, chemical inhalants (pollution) and alcohol.
