Hearing aids enhance sound, filling the gap between natural sound and your child’s diminished ability to hear. While there are several different styles of hearing aids and many manufacturers, all hearing aids consist of the same basic components:

  • Microphone-changes sound waves into electrical impulses
  • Receiver (speaker)-translates the now strengthened electrical impulses into enhanced (louder) sound waves
  • Battery-provides power to operate the hearing aid

A hearing aid works by picking up sound through the microphone, processing that sound into a digital code, and then transmitting the sound to the listener’s ear. Once the sound information is received by the ear, it travels through the listener’s hearing system and then is sent to the brain for processing.

There are different styles of hearing aides available and PENTA’s audiology team will assist you in choosing the most appropriate hearing aid for your child:

  • Behind-the-Ear (BTE)-most frequently recommended for children with hearing loss. The electrical components are housed in a unit that fits behind the ear and the sound is delivered to the ear via an earmold that is custom made to fit your child’s ear. These aids are available in a variety of colors.
  • In-the-Ear (ITE)-not recommended for children until they reach their teens and/or their ear is more adult sized. These hearing aids are custom molded to fill the entire opening of the ear canal.
  • Completely-in-the-Canal-same indication as the ITE and may not be appropriate for more severe degrees of hearing loss. These are custom molded to fit deep inside the ear canal.
