Hearing Aids


Ear

 

The hearing aids of today are sleek, sophisticated pieces of equipment scientifically engineered to delivered the best hearing experience possible. Chances are you can hear the voices that are directly in front of you when in quiet situations, but have trouble hearing when the noise level increases, like when you are in a restaurant with family and friends. The most advanced modern digital hearing aids are designed to constantly analyze the sounds of the various environments and automatically select the appropriate programming mode for specific situations.

 

What is Hearing Aid?

A hearing aid is a battery-powered, electronic device that makes listening easier for people with a hearing loss. A hearing aid consists of a microphone, an amplifier and a receiver. The microphone picks up sounds in your acoustic environment and turns them into electronic signals. The amplifier selectively amplifies the acoustic electronic signals. The receiver is a very small speaker that changes the electric signals back to sounds and delivers the sound to the ear.

 

Types of Hearing Aids:

These are the most common hearing aids:

  • Behind-the-Ear (BTE): The hearing aid sits comfortably behind the ear and is connected by clear tubing to an earmold that fits inside your ear canal. Easy to clean. For mild to severe hearing loss. A BTE instrument connects to the ear canal via a thin transparent tube or a custom-designed ear mold.
  • In-the-Ear (ITE):These fit entirely into your ear. The working parts are either in a small compartment clipped to the earmould or inside the moulded part itself. ITE aids tend to need repairing more often than BTE aids. The hearing aid is contained in a custom shell that sits in the outer part of the ear. Easy to operate and insert. Mild to severe hearing loss.
  • In-the-Canal (ITC): ITC style hearing aids are worn in the lower portion of the outer ear, by the ear canal. Their medium size makes them relatively discreet while offering a secure fit, easy insertion and removal, and longer battery life. A custom mold that sits partly in the ear canal. Discreet and easy to use, even for people with dexterity challenges. Mild to moderate hearing loss.
  • Completely-in-the-Canal (CIC): Virtually invisible, CICs are molded to fit completely into the ear canal. These are even smaller than ITE aids, so they are less visible. They are unlikely to be suitable if you have severe hearing loss or frequent ear infections.May not be suitable for those who have trouble handling small objects. Mild to moderate hearing loss.
  • Invisible Open Technology (IOT): The microphone and tubing follow the contour of the ear. Air can travel in and out of the ear canal which makes voices sound as natural as possible. Best for mild to moderate high frequency losses with normal low frequency hearing.
  • Receiver in the Ear An RIE hearing aid is comprised of a very small casing that sits behind the ear. The casing houses all of the electronic components of the hearing aid except for the receiver. This allows the casing to be extremely tiny, so it’s barely visible. A narrow transparent tube carries very thin wires from the casing to the receiver, which rests in your ear canal.
