A hearing aid is a small electronic hearing assist device that you wear in or behind your ear. It makes some sounds louder. A hearing aid can help people hear more in both quiet and noisy situations.

There are different types of hearing aids. They differ by size, their placement on or inside the ear and how much they amplify sound. The hearing aid that will work best for you depends on what kind of hearing loss you have and how severe it is.


Types of Hearing Aids 

Behind-the-ear Hearing Aids 

Behind-the-ear hearing aids require a custom-fitted mold or a universal dome that is inserted into the ear canal. This earpiece is coupled to the device and is used to direct amplified sound to the ear while maintaining placement. 

Behind-the-ear hearing aids are also:

  • the least expensive style of hearing aid
  • require fewer repairs during the life of the device
  • offer more flexibility in programming and adjustment as a result of a larger fitting range
     

In-the-ear Hearing Aids (Custom)

In-the-ear hearing aids are custom molded to fit each individual’s ears and are available in a variety of sizes.

In-the-ear hearing aids are also:

  • easier to use by patients with dexterity issues 
  • easier to use on landline phones

Hearing Instrument Technology

Automatic Signal Processing

Hearing instruments can monitor your environment and automatically adjust the volume to make speech audible and reduce background noise. Soft sounds are amplified and loud sounds receive little or no amplification. This type of signal processing keeps the output of the hearing instrument comfortable, so manual changes are unnecessary.

Feedback Management

Feedback is the whistling or buzzing noise that a hearing aid can make. Feedback management technology allows hearing aid users access to increased high frequency amplification without feedback. High frequency information carries the sounds of speech responsible for clarity. It is possible to reduce feedback by reducing the volume, though this can affect the clarity of speech. Modern feedback cancelation methods continually monitor the incoming signal and adjust the hearing instrument to minimize feedback without reducing gain.

Noise Management

The inability to hear amidst background noise (in a restaurant or at a party) is a common complaint among people with hearing loss. Modern hearing instruments are able to continually monitor the incoming signals and determine the amount of noise in the environment. They then automatically minimize background noise. This allows the user to listen to speech more comfortably and clearly in noisy environments. 

Directional Technology

Another type of technology that improves speech understanding in noisy environments is the use of directional microphones. Most directional microphone systems help focus on the sounds of interest coming from the front by reducing amplification from the sides and back of the user. The most current directional microphone systems automatically reduce the noise source in the environment.

Wireless Accessories

Wireless accessories are devices that pair with your hearing aids to enable better listening on your Bluetooth compatible cell phone and devices. Wireless accessories can also pair to your television. Ask your audiologists for more detailed information about devices and compatibility.
