HEARING AIDS

• A hearing aid is a small electronic device worn in or behind the ear. It amplifies the sound so that a person with hearing loss can listen, communicate, and participate efficiently in daily activities. A hearing aid can help people hear better in both quiet and noisy situations. However, only about one out of five people who would benefit from a hearing aid actually uses one.
• A hearing aid has three basic parts: a microphone, amplifier, and speaker. The microphone receives the sound and converts the sound waves to electrical signals; the amplifier increases the power of the signals and then sends them to the ear through a speaker. Types of hearing aids
  Pocket modelThe components are housed within a little case that is typically the size of a small match box. It can be worn in a chest pocket or can be clipped in the shirt. A cord is attached to the earpiece.

ADVANTAGES

• Body level hearing aids are sturdy, less expensive to buy and maintain.
  Lower feedbacksqueal.
  Widefitting range from mild to profound hearing loss

BTE – BEHIND THE EAR HEARING AID

BTE hearing aids can provide greater amplification than smaller hearing aids due to the stronger amplifier and the larger battery. This is available programmable, digital, and conventional circuits.

ADVANTAGES

• BTE hearing aids can handle all types of hearing loss.
• BTE instruments are suitable for all ages.
• BTE hearing aids can provide the significant amplification.
• With hair and skin tone matching, BTE hearing aids can be cosmetically appealing with placement behind the ear
• BTE instruments use larger batteries which are easier to handle than the batteries for smaller hearing aids.

CIC – COMPLETELY IN THE CANAL HEARING AID

Completely-in-the-canal (CIC) hearing aids are the smallest size of hearing aids, practically invisible to an observer. Custom designed to fit the wearer’s ear, CIC hearing aids fit deep inside the ear canal and most closely resemble the natural hearing process.

ADVANTAGES

• CIC instruments are the smallest size available, nearly invisible, so they are cosmetically appealing.
• CIC hearing aids provide a close placement of the receiver (speaker) to the eardrum, which gives sound a natural boost in loudness.
• The microphone of a CIC instrument sits in your ear canal, simulating natural sound reception

RIC – RECEIVER IN THE CANAL
Receiver in the Canal (RIC)

These are the newest style of hearing aids available, and look similar to the Open Fit instruments. The main difference between Open Fit and RIC instruments is that for a RIC hearing aid, the receiver is placed inside a small dome in the ear canal. This results in a smaller behind the ear component, more power in the instrument, a discreet aid, less distortion and a natural and comfortable fit.
